Method Details

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
