org.eclipse.emf.edit.command
Class CreateCopyCommand

java.lang.Object
  org.eclipse.emf.common.command.AbstractCommand
      org.eclipse.emf.edit.command.AbstractOverrideableCommand
          org.eclipse.emf.edit.command.CreateCopyCommand

All Implemented Interfaces:

ChildrenToCopyProvider, Command, OverrideableCommand

public class CreateCopyCommand

extends AbstractOverrideableCommand

implements ChildrenToCopyProvider

The create copy command is used to create an uninitialized object of the same type as owner which will later be initialized using InitializeCopyCommand.

A create copy command is an OverrideableCommand.

This caches the label.

DESCRIPTION

protected static final String DESCRIPTION

This caches the description.

owner

protected EObject owner

This is the object being copied.

copy

protected EObject copy

This is the copy.

copyHelper

protected CopyCommand.Helper copyHelper

This is a map of objects to their copies

Constructor Detail

CreateCopyCommand

public CreateCopyCommand(EditingDomain domain,
                         EObject owner,
                         CopyCommand.Helper copyHelper)

This constructs a command that will create an object that is a copy of the given object.

Method Detail

create

public static Command create(EditingDomain domain,
                             Object owner,
                             CopyCommand.Helper copyHelper)

This creates a command that will create and object for copying the given object

getOwner

public EObject getOwner()

This is the object being copied.

getCopyHelper

public CopyCommand.Helper getCopyHelper()

This is the map of objects to their copies.

prepare

protected boolean prepare()

Description copied from class: AbstractCommand

Called at most once in AbstractCommand.canExecute() to give the command an opportunity to ready itself for execution. The returned value is stored in AbstractCommand.canExecute(). In other words, you can override this method to initialize and to yield a cached value for the all subsequent calls to canExecute.

Overrides:

prepare in class AbstractCommand

Returns:

whether the command is executable.

doExecute

public void doExecute()

Description copied from interface: OverrideableCommand

This is overrideable command's implementation of execute.

Specified by:

doExecute in interface OverrideableCommand

Specified by:

doExecute in class AbstractOverrideableCommand

doUndo

public void doUndo()

Description copied from interface: OverrideableCommand

This is overrideable command's implementation of undo.

Specified by:

doUndo in interface OverrideableCommand

Specified by:

doUndo in class AbstractOverrideableCommand

doRedo

public void doRedo()

Description copied from interface: OverrideableCommand

This is overrideable command's implementation of redo.

Specified by:

doRedo in interface OverrideableCommand

Specified by:

doRedo in class AbstractOverrideableCommand

doGetResult

public Collection doGetResult()

Description copied from interface: OverrideableCommand

This is overrideable command's implementation of getResult.

Specified by:

doGetResult in interface OverrideableCommand

Overrides:

doGetResult in class AbstractOverrideableCommand

doGetChildrenToCopy

public Collection doGetChildrenToCopy()

Overrides:

doGetChildrenToCopy in class AbstractOverrideableCommand

toString

public String toString()

This gives an abbreviated name using this object's own class' name, without package qualification, followed by a space separated list of field:value pairs.

Overrides:
