Constructor Detail

FeatureCache

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

Constructs a FeatureCache using ArcGIS Engine.

Throws:

java.io.IOException - if there are interop problems

java.net.UnknownHostException - if there are interop problems

FeatureCache

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

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

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

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 FeatureCache.

Specified by:

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

initialize
