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

java.lang.Object
  extended by 
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).
 
Methods inherited from class java.lang. Object
clone, equals, finalize, getClass, hashCode, notify, notifyAll, toString, wait, wait, wait
