Constructor Detail

EReferenceItemProvider

public EReferenceItemProvider(AdapterFactory adapterFactory)

This constructs an instance from a factory and a notifier.

Method Detail

getPropertyDescriptors

public java.util.List<IItemPropertyDescriptor> getPropertyDescriptors(java.lang.Object object)

This returns the property descriptors for the adapted class.

Specified by:

getPropertyDescriptors in interface IItemPropertySource

Overrides:

getPropertyDescriptors in class EStructuralFeatureItemProvider

addContainmentPropertyDescriptor

protected void addContainmentPropertyDescriptor(java.lang.Object object)

This adds a property descriptor for the Containment feature.

addContainerPropertyDescriptor

protected void addContainerPropertyDescriptor(java.lang.Object object)

This adds a property descriptor for the Container feature.

addResolveProxiesPropertyDescriptor

protected void addResolveProxiesPropertyDescriptor(java.lang.Object object)

This adds a property descriptor for the Resolve Proxies feature.

addEOppositePropertyDescriptor

protected void addEOppositePropertyDescriptor(java.lang.Object object)

This adds a property descriptor for the EOpposite feature.

addEReferenceTypePropertyDescriptor

protected void addEReferenceTypePropertyDescriptor(java.lang.Object object)

This adds a property descriptor for the EReference Type feature.

addEKeysPropertyDescriptor

protected void addEKeysPropertyDescriptor(java.lang.Object object)

This adds a property descriptor for the Keys feature.
