org.eclipse.ltk.core.refactoring.participants
Class CheckConditionsContext  

java.lang.Object
  org.eclipse.ltk.core.refactoring.participants.CheckConditionsContext

---

public class CheckConditionsContext

extends java.lang.Object

A context that is shared between the refactoring processor and all its associated participants during condition checking.

The context manages a set of IConditionCheckerobjects to collect condition checks that should be perform across all participants and the processor. For example validating if a file can be changed (see IWorkspace.validateEdit(org.eclipse.core.resources.IFile[], java.lang.Object)>IWorkspace.validateEdit(org.eclipse.core.resources.IFile[], java.lang.Object) 55 should only be called once for all files modified by the processor and all participants.

Note: this class is not intended to be extended by clients.

Since:

3.0
