Examples of MetadataDescriptor

com.halware.nakedide.eclipse.ext.annot.mdd.MetadataDescriptor
Represents some metadata (annotation or other information) about a class, a property/collection/action of a class, or a parameter of an action.
oracle.toplink.essentials.internal.ejb.cmp3.metadata.MetadataDescriptor
Common metatata descriptor for the annotation and xml processors. This class is a wrap on an actual TopLink descriptor. @author Guy Pelletier @since TopLink EJB 3.0 Reference Implementation
org.apache.muse.ws.resource.metadata.MetadataDescriptor
MetadataDescriptor is an interface for a single metadata descriptor. It defines a lookup service for property metadata; in addition to actual metadata values, the interface has convenience methods for answering common questions ("Can I delete this property?", etc.) rather than requiring the user to calculate the answers based on metadata values. This interface is based on WS-RMD 1.0. @author Dan Jemiolo (danj)
