Class ItemProviderAdapter.ResultAndAffectedObjectsWrappingCommand

java.lang.Object
  org.eclipse.emf.common.command.AbstractCommand
      org.eclipse.emf.common.command.CommandWrapper
          org.eclipse.emf.edit.provider.ItemProviderAdapter.ResultAndAffectedObjectsWrappingCommand

All Implemented Interfaces:

Direct Known Subclasses:

Enclosing class:

ItemProviderAdapter

public class ItemProviderAdapter.ResultAndAffectedObjectsWrappingCommand

extends CommandWrapper

A ResultAndAffectedObjectsWrappingCommand wraps another command to substitute IWrapperItemProviders for their values in the command's result and affected objects. This is needed as the values have been unwrapped for the command to operate on properly.

A list of wrappers from which to substitute is formed by calling getChildren on the command's owner(s). Additional wrappers to be considered for the result can by specified in the two-argument constructor. The first wrapper whose value matches a given value in the result or affected objects is substitued for it.
