public interface IFeatureWorkspaceManage
Provides access to dataset deletion and renaming, table and index analysis, field validation and version and object class registration .
The IFeatureWorkspaceManage interface contains utility methods that help in the management of feature workspaces.

| Method Detail |
|---|
void deleteByName(IDatasetName aName)
throws IOException,
AutomationException
The DeleteByName method can be used to delete a dataset given its name object. It can be useful when cleaning up partially loaded datasets that cannot be instantiated because of incomplete information. It is made use of by ArcCatalog’s delete command. Note that IDataset::Delete is directly available as a method on instantiated datasets.
The DeleteByName method will fail when called on feature classes that participate in geometric networks or topologies. In these cases, the containing dataset, a Geometric Network or Topology, must be deleted first in order to demote the feature classes from non-simple to simple.
aName - A reference to a com.esri.arcgis.geodatabase.IDatasetName (in)
IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.
boolean isRegisteredAsVersioned(IName aName)
throws IOException,
AutomationException
IsRegisteredAsVersioned indicates if a particular object in the workspace is versioned. This property applies only to objects stored in an ArcSDE workspace. You can register and unregister objects as versioned using the RegisterAsVersioned method on IVersionedObject.
aName - A reference to a com.esri.arcgis.system.IName (in)
IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.
boolean isRegisteredAsObjectClass(String name)
throws IOException,
AutomationException
IsRegisteredAsObjectClass indicates if an object in the database is referenced in the Geodatabase system tables. A table created using SQL, or an SDE layer created using the ArcSDE administration commands, or other ArcSDE client software are examples of objects that are not registered with the Geodatabase. These tables will have an ObjectClassID of -1.
You can use the RegisterAsObjectClass method on IClassSchemaEdit to register an object with the Geodatabase.
name - The name (in)
IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.
boolean canDelete(IName aName)
throws IOException,
AutomationException
aName - A reference to a com.esri.arcgis.system.IName (in)
IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.
boolean canRename(IName aName)
throws IOException,
AutomationException
aName - A reference to a com.esri.arcgis.system.IName (in)
IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.
void analyzeTable(String tableName,
int tableComponents)
throws IOException,
AutomationException
The AnalyzeTable and AnalyzeIndex methods can be used to acquire DBMS statistics on tables and table indexes. Having up-to-date statistics on a table is key to efficient query performance on the table and a key requirement for efficient queries against versioned tables. Note that datasets that are based on tables support the IDatasetAnalyze method; to analyze all of the tables in a feature dataset, use the IDatasetAnalyze::Analyze method on the feature dataset.
The TableComponents arguement takes values from the enumeration esriTableComponents. These values include esriAddsTable, esriBusinessTable, esriDeletesTable, esriFeatureTable, and esriRasterTable. The values can also be combined together. For example, to analyze the business, adds, and deletes table, you would specify (esriBusinessTable + esriAddsTable + esriDeletesTable)
tableName - The tableName (in)tableComponents - The tableComponents (in)
IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.
void analyzeIndex(String tableName,
String index)
throws IOException,
AutomationException
The AnalyzeTable and AnalyzeIndex methods can be used to acquire DBMS statistics on tables and table indexes. Having up-to-date statistics on a table is key to efficient query performance on the table and a key requirement for efficient queries against versioned tables. Note that datasets that are based on tables support the IDatasetAnalyze method; to analyze all of the tables in a feature dataset, use the IDatasetAnalyze::Analyze method on the feature dataset.
tableName - The tableName (in)index - The index (in)
IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.
IField validateField(IField inField)
throws IOException,
AutomationException
The ValidateField method takes a Field definition as input, and based on its field type, scale and precision, returns a field definition that represents more closely how that field is actually stored in the database.
For example, a field whose type is esriFieldTypeSingle and its precision and scale are 0, then it will actually be stored in the database as a double.
inField - A reference to a com.esri.arcgis.geodatabase.IField (in)
IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.
