public class ObjectClass
ESRI Object Class object.
An object class is a table whose rows represent entities, modeled as objects with properties and behavior. The row objects handed out by an object class support the IRow and the IObject interfaces.
An object class may participate in any number of relationship classes that relate its instances to objects (entities) in other object classes.
An object class may contain a discriminating field, referred to as the subtype field that may be used to partition its instances into a number of subtypes. All subtypes share the same field definition and are stored in the same table, however individual subtypes may differ in the default values and domains assigned to fields. The subtyping mechanism can also be used in defining attribute and connectivity rules that apply to the instances of the object class. The subtyping mechanism is a lightweight alternative to creating multiple subclasses each represented by its own object class.
An object class has a non-negative object class ID which is unique within the geodatabase. This ID is assigned to the object class at the time that it is created or at the time that an existing table in the RDBMS is registered with the geodatabase as an object class. The Name of the object class is the same as the name of the table in the DBMS in which the objects in the object class are stored and follows the same fully qualified naming conventions.
An object class may have an AliasName property that is stored as part of its definition by the geodatabase. The AliasName may be retrieved and used for display purposes by applications.
An object class may have a ModelName property that is stored as part of its definition by the geodatabase. The model name is not exposed to end users and if defined, can be used as a search key to find an object class by a standard model name that is adhered to across databases. A model name must be unique across the workspace.

public String getCategory()
throws IOException,
AutomationException
IDataset::Category returns a description of the category of the dataset. The description returned from the Category property is the same value that is displayed in the Type column within the Contents tab in ArcCatalog. The value will contain a description of the dataset such as "Topology" prefixed with a description of the type of workspace containing the dataset such as "File Geodatabase".
The description returned from IDataset::Category may change between releases of ArcGIS. In addition to this, returned strings are localized, meaning that code relying on a specific string being provided may fail when deployed with a different version of ArcGIS than it was developed with, or when deployed to a client using a different language than it was developed with.

public IPropertySet getPropertySet()
throws IOException,
AutomationException
The PropertySet property is used to return any additional intrinsic properties (but not metadata properties) that may apply to the dataset. One use of this property is to distinguish between the types of File Geodatabase datafile formats. If called on a Feature Class or Table in a File Geodatabase the Datafile Format property can either be esriFGDBStandardDatafile or esriFGDBCompressedDatafile.
Most datasets do not implement this property and will either raise an error or return a null value if it's called. There are a handful of exceptions that will return property sets; these include the datasets from file geodatabases (as mentioned above) and coverages.
Examples of intrinsic properties for which explicit methods exist include the SpatialReference and the Extent methods available on the IGeoDataset interface. In most cases this PropertySet will be empty.
IDataset::PropertySet is not supported for Graph objects such as a Geometric Network.
getPropertySet in interface IDatasetIOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.

IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.
public boolean isBeingEdited()
throws IOException,
AutomationException
Once an edit session has been started on a workspace, the IsBeingEdited method on the IDatasetEdit interface can be used to determine if a particular dataset is participating in the edit session.
The reasons why a dataset may not participate include the connected user has no privileges or permission to edit the dataset, the connected user is not licensed to edit this type of dataset, or the dataset is not versioned but a versioned edit session has been started (or vice versa).
isBeingEdited in interface IDatasetEditIOException - If there are interop problems.

IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.
public void getCurrentSchemaLocks(IEnumSchemaLockInfo[] schemaLockInfo)
throws IOException,
AutomationException
The ISchemaLockInfo interface is used in concert with ISchemaLock to provide information about a schema lock, for example, whether it is shared or exclusive and for ArcSDE geodatabases, the name of the user who has the lock. Note that there will always be at least one schema lock on the dataset. Also note that by checking the schema locks on a dataset a shared schema lock is applied to the data.

public IRow createRow()
throws IOException,
AutomationException
The CreateRow method creates a new row in the underlying database with a system assigned object id value. A row object representing the created row is returned to the caller. The row object returned has the system assigned object ID as the value of the OIDField. All other fields are initialized to null values if they can be made null and to built-in default values appropriate to the type of the field if they cannot be made null.
The caller is responsible for setting the desired field values into the row and calling the Store method on the row. If the table represents an object class with subtypes, then it is the caller’s responsibility to set the default subtype code into the row and call the InitDefaultValues method on the row before storing, if that is the desired result. For tables without object behavior, insert cursors offer a more efficient way for inserting new rows.
createRow in interface ITableIOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.
public IRow getRow(int oID)
throws IOException,
AutomationException
The GetRow method returns an existing row object, given its object ID value. The caller can query the returned row object for additional object specific interfaces. The retrieved row may be modified; calling Store on the row object after changing it will trigger messages to related objects and will mark the row for committing to the database.
getRow in interface ITableoID - The oID (in)
IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.
public ICursor getRows(Object oids,
boolean recycling)
throws IOException,
AutomationException
The GetRows method returns a cursor that may be used to retrieve a set of rows specified by the input array of object id values. See the description of the Search method to understand the meaning of the recycling parameter. It is far more efficient to retrieve a set of rows using the GetRows method than it is to retrieve each individual row using the GetRow method. The retrieved rows may be modified; Store should be called on the row objects after changing them.
The oids parameter should be passed an integer array. For example:
// Get a recycling cursor for the OID array.
int[] oids = new int[] { 10844, 10853, 10871 };
ICursor cursor = table.getRows(oids, true);
getRows in interface ITableoids - A Variant (in)recycling - The recycling (in)
IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.
public IRowBuffer createRowBuffer()
throws IOException,
AutomationException
The CreateRowBuffer method creates a new row buffer object in memory and returns it to the caller. No row is created in the database. The returned row buffer does not have an object ID value. The caller can set values into the row buffer and use it as an argument to the InsertRow method on an insert cursor; the latter is obtained by calling the Insert method on the Table.
createRowBuffer in interface ITableIOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.
public void updateSearchedRows(IQueryFilter queryFilter,
IRowBuffer buffer)
throws IOException,
AutomationException
This method will edit the rows matching the query filter's constraints. The values in each row will be replaced with the corresponding field's value in the provided row buffer. The fields being edited should be specified in the query filter's SubFields property. If the row buffer contains null values, and the SubFields property is not properly set, the row's values will be overwritten with the row buffer's null values.

The Update method returns an update cursor that can be used to update or delete rows. It offers somewhat faster performance than multiple calls to Store or Delete on row objects fetched using a non-recycling search cursor for tables storing simple rows and simple features. There is no difference in performance for complex objects and features.
When using cursors within an edit session, they should always be scoped to edit operations. In other words, a cursor should be created after an edit operation has begun and should not be used once that edit operation has been stopped or aborted.

The Select method returns a selection set that holds either row IDs or row objects from the Table depending on the selection option. Multiple selection sets can be created on the same table. It is up to a client application or object to keep a reference on created selections and use them as appropriate. For example, a FeatureLayer creates and uses selections on a FeatureClass (a type of Table).
The selType parameter determines the type of selection set that will be created: an ID set, a snapshot, or a hybrid. See the ISelectionSet interface for a comparison of the three types.
When calling Select the selectionContainer parameter is no longer required. A null value should be passed as this parameter.

Returns the unique ID of the object class.
Each feature class or table registered with the geodatabase is an object class. Object classes have a unique ID which distinguishes them from other object classes in the geodatabase. The ObjectClassID property returns this ID as a long. The object class ID is assigned by the system when the class is created, or registered with the geodatabase, it cannot be modified.

The RegisterAsObjectClass method will register a table or feature class (ArcSDE layer) in the database with the Geodatabase. The act of registering the data as an object class will create records for the object class in the Geodatabase system tables and assign the object class a unique ID. Once a table or SDE layer is registered as an object class, it can participate in rules, topological relationships and relationships.
When registering a table or ArcSDE layer as an object class, an ObjectID field must be added to it. This field will contain the object IDs which uniquely identify each feature in the class. The object IDs for existing data will automatically be generated. Once a table or ArcSDE layer has been registered as an object class in the Geodatabase, it cannot be unregistered.
RegisterAsObjectClass takes two arguments: the name of the object ID field, and the ArcSDE configuration keyword to use for storage of the new data that is inserted into the object ID field. RegisterAsObjectClass returns a long which is the object class ID assigned to the newly registered class.

Domains are used in the Geodatabase to validate the contents of fields in an object class. For example, you can use a domain to specify a valid range of values, or a valid set of values for a particular field in an object class. You can assign domains to a field in an object class at either the class level, or the subtype level. The AlterDomain method on IClassSchemaEdit allows you to set a domain for a field at the class level.
AlterDomain takes as arguments the name of the field you want to associate a domain with as a string, and the domain you are associating as an IDomain. You can get an enumeration of domains in a workspace by calling the Domains or DomainsByFieldType methods on the IWorkspaceDomains interface.
Once a domain is associated with a field in your object class, the values in that field will be validated against that domain when a row in the object class is validated with the IValidate interface, or the Validate Selection command in the Editor.

Additionally the dataset must not be replicated. Use the IWorkspaceReplicasAdmin2::IsReferencedByReplica method to determine if the dataset is part of a replica.
A Global ID field must not already exist on the dataset referenced by the object. Use the IClassEx::HasGlobalID property to determine if a dataset has a Global ID field.
The columnName must reference a field of type GUID in the dataset referenced by the object. The IField::Type property can be used to determine a field type.
There must be no duplicate values in the GUID field. See the DataStatistics coclass for more information.
Another requirement is that the GUID field must be not nullable. See the IField::IsNullable property for more information. By default, GUID columns are nullable. However, when adding a GUID column to a dataset you can specify this field be not nullable. This is possible whether or not the dataset you are adding the new GUID field to already has populated rows. If you add a GUID column to a popluated dataset, and set the IsNullable property of this field to be false, the GUID values will be populated with a default value of {00000000-0000-0000-0000-000000000000}.
If you have a GUID field but it is nullable, to satisfy the requirements of this method, you can simply add a new GUID field, ensure you set the IsNullable property to false, and calculate the values from your GUID field into the newly added GUID field.

Additionally, you can query the HasSubtype property; a value of False indicates an absence of a default subtype code, True indicates the presence of a default subtype code.
If the client instead asks for the enumeration of subtypes associated with an ObjectClass and no subtype has been previously added to the ObjectClass, then the enumerator will contain a single entry with a code of zero. The subtype field index value will be –1 if a default subtype has not been previously specified. Subtypes may only be short or long integers (esriFieldTypeSmallInteger or esriFieldTypeInteger). When setting the default subtype code, if one already exists, then it will be deleted. A subtype field must have been specified prior to setting the subtype code value.
Every type of field, except for esriFieldTypeShape, may have a default value. When setting the default value (which my be assigned on a subtype basis), it will be checked against the field’s associated Domain (if one exists) for validity.

throws IOException,
AutomationException
CanBypassStoreMethod is a convenience method that returns True if the instances of this object class have no custom behavior associated with creating or updating objects and if the object class does not participate in composite relationship classes or in relationship classes that require object notification. A return value of True implies that insert cursors handed out by the geodatabase will internally bypass the CreateRow and Store mechanisms when creating objects. A return value of False indicates that insert cursors will not bypass custom Store or OnChanged behavior implemented by the custom row object for this class.
By default, this method returns False for custom object classes. The developer of a custom object class can change this behavior by implementing this interface on the class extension associated with the class and returning True for the method.
In addition, a developer can implement this interface on the class extension of a simple class and set this property to False . Doing this will ensure that when features in the class are inserted, updated or deleted by editor tools that use insert and update cursors, such as Planarize, Create Features and the Object Loader do not bypass Store or OnChanged behavior. By default, this property for a simple class is logically True, meaning these tools will not broacast Geodatabase events which in turn are not rebroadcast as editor events (for which a custom editor application may be listening). Set this to False for those classes for which you always want to have these events broadcast. Alternatively, this can be set globally for the entire edit session using the IWorkspaceEditControl interface.

CanBypassEditSession is a convenience method that returns True if the instances of this object class may be created or updated outside of a Geodatabase edit session (an edit session is started by using the StartEditing method on the IWorkspaceEdit or the StartMultiuserEditing method on the IMultiuserWorkspaceEdit interface).
If True , then applications may update the data in this object class using any of the data updating interfaces and methods described here without starting an edit session. In this case applications are responsible for starting host database transactions as appropriate and for discarding cached object states across transaction boundaries when running on an ArcSDE database.
If False, then applications should always make modifications to the data in this object class within an edit session for correct multi-user behavior and for correct management of database state internally cached by the Geodatabase for the objects in this object class.
This method returns False for network feature classes. By default, this method returns True for non-network custom object classes. The developer of a non-network custom object class can change this behavior by implementing this interface on the class extension associated with the class and returning true for the method.
