                    throws IOException,
                           UnknownHostException

Constructs a EnumFeatureGeometry using ArcGIS Engine.

UnknownHostException - if there are interop problems

EnumFeatureGeometry

public EnumFeatureGeometry(Object obj)
                    throws IOException

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

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

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

next

                      AutomationException

Returns the next geometry in the enumeration.

Description

Returns the Next Geometry part from the current enumeration location.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Supported Platforms

Windows, Solaris, Linux

Specified by:

next in interface IEnumGeometry

Returns:

A reference to a com.esri.arcgis.geometry.IGeometry

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

reset

public void reset()
           throws IOException,
                  AutomationException

Starts the enumeration at the beginning.

Description

Resets the current enumeration location to the null pointer at the beginning of the enumeration such that the Next Geometry is the first Geometry part in the enumeration.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Supported Platforms

Windows, Solaris, Linux

Specified by:

reset in interface IEnumGeometry

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

getCount

public int getCount()
             throws IOException,
                    AutomationException

The number of geometries in the enumeration.

Description

Returns the number of distinct geometry parts in the enumeration. This count is the same as the count returned by GeometryCount in a GeometryCollection.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Supported Platforms

Windows, Solaris, Linux

Specified by:

getCount in interface IEnumGeometry

Returns:

The geometryCount

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

bindGeometrySource

public void bindGeometrySource(IQueryFilter outputFilter,
                               Object collectionSource)
                        throws IOException,
                               AutomationException

Bind the source of the geometry to the enumeration.

Description

This method binds the enumerator to a geometry source (a feature class or a selection set). After this method has been invoked on an object, the object can be cast to the IEnumGeometry interface in order to iterate through the geometries of the source.

Remarks

A query filter should always be provided to the OutputFilter parameter. Passing a null value will not result in an error, but when using this interface the only field that can be inspected from returned features is the geometry field, and the query filter should reflect this.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Parameters:

outputFilter - A reference to a com.esri.arcgis.geodatabase.IQueryFilter (in)
