Constructor Detail

DimensionClassExtension

public DimensionClassExtension()
                        throws IOException,
                               UnknownHostException
Constructs a DimensionClassExtension using ArcGIS Engine.

Throws:
IOException - if there are interop problems
UnknownHostException - if there are interop problems

DimensionClassExtension

public DimensionClassExtension(Object obj)
                        throws IOException
Deprecated. As of ArcGIS 9.2, replaced by normal Java casts.
DimensionClassExtension theDimensionClassExtension = (DimensionClassExtension) obj;

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

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

init

public void init(IClassHelper classHelper,
                 IPropertySet extensionProperties)
          throws IOException,
                 AutomationException
Initializes the extension, passing in a reference to its class helper.

Remarks

If a reference to the class is required by other class extension members, the class helper should be stored in a member variable. Storing an object or feature class directly within a class extension is strongly discouraged.

Product Availability

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

Supported Platforms

Windows, Solaris, Linux

Specified by:
init in interface IClassExtension
Parameters:
classHelper - A reference to a com.esri.arcgis.geodatabase.IClassHelper (in)
extensionProperties - A reference to a com.esri.arcgis.system.IPropertySet (in)
Throws:
IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.

shutdown

public void shutdown()
              throws IOException,
                     AutomationException
Informs the extension that its class helper is going away.

Remarks

Shutdown is called when the extension's class is cleared from the client's memory, or when the extension is removed from the class. Note that if a class is deleted from a geodatabase, it may remain in memory, so this should not be relied upon for behavior that should be triggered by a class' deletion.

Product Availability

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