Examples of org.apache.ojb.broker.metadata.ArgumentDescriptor

org.apache.ojb.broker.metadata.ArgumentDescriptor
An ArgumentDescriptor contains information that defines a single argument that is passed to a procedure/function.
Note: Be careful when use ArgumentDescriptor variables or caching ArgumentDescriptor instances, because instances could become invalid during runtime (see {@link MetadataManager}). @author Ron Gallagher @version $Id: ArgumentDescriptor.java,v 1.8.2.1 2005/12/21 22:26:10 tomdz Exp $
