public abstract class MutateEvent

extends Event

An event representating a 'mutation', that is modification in place to a data item previously added to the dataspace (NB Not currently implemented - June 2003).

Field Summary

GUID	id The id of the item in the dataspace to have the mutator applied to it
ItemMutator	mutator The application-defined subclass of ItemMutator to be applied to the specified item

getModuleName

public java.lang.String getModuleName()

IDL-generated helper routine to get module name (currently unimplemented).

Overrides:

getModuleName in class Event

Returns:

name of this class's module

equals

public boolean equals(java.lang.Object c)

Standard IDL-generated equality test.

Overrides:

equals in class Event

Parameters:
