Constructor Detail

Field

public Field()
      throws IOException,
             UnknownHostException

Constructs a Field using ArcGIS Engine.

Throws:

IOException - if there are interop problems

UnknownHostException - if there are interop problems

Field

public Field(Object obj)
      throws IOException

Deprecated. As of ArcGIS 9.2, replaced by normal Java casts.
Field theField = (Field) obj;

Construct a Field using a reference to such an object returned from ArcGIS Engine or Server. This is semantically equivalent to casting obj to Field.

Parameters:

obj - an object returned from ArcGIS Engine or Server

Throws:

IOException - if there are interop problems

Method Detail

getClsid

public static String getClsid()

getClsid.

equals

public boolean equals(Object o)

Compare this object with another

Overrides:

equals in class Object

hashCode

public int hashCode()

the hashcode for this object

Overrides:

hashCode in class Object

getName

public String getName()
               throws IOException,
                      AutomationException

The name of the field.

Remarks

Geodatabase feature classes, depending on their geometry type, may contain automatically generated fields for shape length and area. In personal and file geodatabases, these fields will be named using the name of the shape field suffixed with "_Length" and "_Area". In an SDE geodatabase, the names of these fields will be dependant on the underlying DBMS.

The IFeatureClass::ShapeFieldName property should be used to determine the name of the length and area fields for a feature class.
