Class DelegatingWrapperItemProvider.DelegatingWrapperItemPropertyDescriptor

java.lang.Object
  org.eclipse.emf.edit.provider.ItemPropertyDescriptorDecorator
      org.eclipse.emf.edit.provider.DelegatingWrapperItemProvider.DelegatingWrapperItemPropertyDescriptor

All Implemented Interfaces:

IItemPropertyDescriptor, IItemPropertyDescriptor.OverrideableCommandOwner

Enclosing class:

DelegatingWrapperItemProvider

protected class DelegatingWrapperItemProvider.DelegatingWrapperItemPropertyDescriptor
extends ItemPropertyDescriptorDecorator
implements IItemPropertyDescriptor.OverrideableCommandOwner

A DelegatingWrapperItemPropertyDescriptor decorates an ItemPropertyDescriptor and manages a command owner override. If its command owner is non-null, it ensures that the decorated descriptor, if it also implements OverrideableCommandOwner, will have its command owner set to the same object when resetPropertyValue or setPropertyValue is called. If its command owner is null, then the decorated descriptors's command owner will be set to this wrapper item provider.
