Constructor Detail

FeatureClassDescriptor

public FeatureClassDescriptor()
                       throws java.io.IOException,
                              java.net.UnknownHostException

Constructs a FeatureClassDescriptor using ArcGIS Engine.

Throws:

java.io.IOException - if there are interop problems

java.net.UnknownHostException - if there are interop problems

FeatureClassDescriptor

public FeatureClassDescriptor(java.lang.Object obj)
                       throws java.io.IOException

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

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

Parameters:

obj - an object returned from ArcGIS Engine or Server

Throws:

java.io.IOException - if there are interop problems

Method Detail

getClsid

public static java.lang.String getClsid()

getClsid.

equals

public boolean equals(java.lang.Object o)

Compare this object with another

Overrides:

equals in class java.lang.Object

hashCode

public int hashCode()

the hashcode for this object

Overrides:

hashCode in class java.lang.Object

getJintegraDispatch

public com.esri.arcgis.interop.Dispatch getJintegraDispatch()

Deprecated. Internal use only.

Specified by:

getJintegraDispatch in interface com.esri.arcgis.interop.RemoteObjRef

release

public void release()

Release a FeatureClassDescriptor.

Specified by:

release in interface com.esri.arcgis.interop.RemoteObjRef

getSpatialReference

public ISpatialReference getSpatialReference()
                                      throws java.io.IOException,
                                             AutomationException

The spatial reference of the GeoDataset.

Remarks

This property is read only. For layers, when the first layer is added to ArcMap, its spatial reference is read by this property, and the map is set to this spatial reference.

Instances of the esriCarto.GroupLayer class will return null for this property, as a group layer can contain multiple datasets with different spatial references.

Modifications to a spatial reference returned by this property will not be persisted. To modify the spatial reference of a dataset, the IGeoDatasetSchemaEdit and IGeoDatasetSchemaEdit2 interfaces should be used.

Product Availability

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

Supported Platforms

Windows, Solaris, Linux

Specified by:

getSpatialReference in interface IGeoDataset

Returns:

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

Throws:

java.io.IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

getExtent

public IEnvelope getExtent()
                    throws java.io.IOException,
                           AutomationException

The extent of the GeoDataset.

Remarks

The IGeoDataset::Extent property returns an envelope representing the maximum extent of data which has been stored in the dataset.

Consider the following scenario. A new feature class has features added to it. The IGeoDataset::Extent is then requested and an envelope is returned. The extents of the envelope returned are represented by the red box in the image below.

If a portion of the features were then deleted and the extent is again requested an envelope with the exact same extents as during the first request would be returned (see image below). This is because the deletion of features does not shrink the extent. However all additions of features outside the red box would increase the envelope returned to encompass the newly added features.

If you would like to update the IGeoDataset::Extent property to reflect the current features in your dataset please see IFeatureClassManage::UpdateExtent (also see IFeatureClassLoad). In the image below the extent has been updated and a new envelope is being returned.

ESRI's GroupLayer implements this property differently from most other layer coclasses. When you instantiate a new GroupLayer, this property will return a valid envelope with zero height and width. With most other newly instantiated layers (for example FeatureLayer, RasterLayer, TinLayer), this property initally returns Nothing.
