Examples of ITypeDescriptor

org.eclipse.jst.jsf.context.symbol.ITypeDescriptor
org.eclipse.jst.jsf.metadataprocessors.ITypeDescriptor
Interface describing the runtime type of a metadata enabled annotation. The type descriptor will load the feature adapters for a certain kind of feature that it supports. The type descriptor is registered by an extension point.
