Method Detail

getDescriptor

public 
ChangeDescriptor getDescriptor()
Description copied from class: Change
Returns a descriptor of this change.

Subclasses of changes created by Refactoring.createChange(IProgressMonitor) should override this method to return a RefactoringChangeDescriptor. A change tree created by a particular refactoring is supposed to contain at most one change which returns a refactoring descriptor. Refactorings usually return an instance of CompositeChange in their Refactoring.createChange(IProgressMonitor) method which implements this method. The refactoring framework searches the change tree top-down until a refactoring descriptor is found.

Overrides:
getDescriptor in class Change
Returns:
a descriptor of this change, or null if this change does not provide a change descriptor.

setDescriptor

public void setDescriptor(
ChangeDescriptor descriptor)
Sets the change descriptor to be returned by Change.getDescriptor().

Parameters:
descriptor - the change descriptor

perform

public final 
Change perform(
IProgressMonitor monitor)
                     throws 
CoreException,
                            
OperationCanceledException
Description copied from class: Change
Performs this change. If this method is called on an invalid or disabled change object the result is unspecified. Changes should in general not respond to IProgressMonitor.isCanceled() since canceling a change tree in the middle of its execution leaves the workspace in a half changed state.

Specified by:
perform in class Change
Parameters:
monitor - a progress monitor
Returns:
the undo change for this change object or null if no undo is provided
Throws:
CoreException - if an error occurred during change execution
OperationCanceledException

getModifiedResource

protected 
IResource getModifiedResource()
Description copied from class: ResourceChange
Returns the resource of this change.

Specified by:
getModifiedResource in class ResourceChange
Returns:
the resource of this change

getName

public 
String getName()
Description copied from class: Change
Returns the human readable name of this change. The name MUST not be null.

Specified by:
getName in class Change
Returns:
the human readable name of this change
