public class CreateChangeOperation extends Object implements IWorkspaceRunnable
Changeobject for a given refactoring. If created with a refactoring object directly, no precondition checking is performed. If created with a
CheckConditionsOperationthe requested precondition checking is performed before creating the change.
If the precondition checking returns a fatal error or the status's severity exceeds a certain threshold then no change will be created.
If a change has been created the operation calls
to initialize the change's validation data.
The operation should be executed via the run method offered by
IWorkspace to achieve proper delta batching.
Note: this class is not intended to be extended by clients.
