org.eclipse.emf.transaction.ui.provider
Class TransactionalPropertySource

java.lang.Object
  
org.eclipse.emf.transaction.ui.provider.TransactionalPropertySource

All Implemented Interfaces:

IPropertySource, IPropertySource2

---

public class TransactionalPropertySource
extends 
Object
implements 
IPropertySource2

A property source wrapper that calls its delegate in transactions of the appropriate kind. Note that transactions are not actually required for methods that do not access model objects.

---

Constructor Summary
TransactionalPropertySource ( TransactionalEditingDomain domain, IPropertySource propertySource)           Initializes me with the editing domain in which I create transactions, and the property source that I delegate to.

 

Method Summary
Object	getEditableValue ()           Delegates the my wrapped property source in the appropriate transaction.
IPropertyDescriptor[]	getPropertyDescriptors ()           Delegates the my wrapped property source in the appropriate transaction.
Object	getPropertyValue ( Object id)           Delegates the my wrapped property source in the appropriate transaction.
boolean	isPropertyResettable ( Object id)           Delegates the my wrapped property source in the appropriate transaction.
boolean	isPropertySet ( Object id)           Delegates the my wrapped property source in the appropriate transaction.
void	resetPropertyValue ( Object id)           Delegates the my wrapped property source in the appropriate transaction.
protected <T> T	run ( RunnableWithResult<? extends T> run)           Runs the specified runnable in the editing domain, with interrupt handling.
void	setPropertyValue ( Object id, Object value)           Delegates directly to the wrapper property source, because it will use a command to perform the modification (which implicitly creates a read/write transaction).
