Examples of net.jini.core.entry.Entry

net.jini.core.entry.Entry
This class is the supertype of all entries that can be stored in a Jini Lookup service.
Each field of an entry must be a public reference (object) type. You cannot store primitive types in fields of an Entry. An Entry may have any number of methods or constructors. Each field is serialized separately, so references between two fields of an entry will not be reconstituted to be shared references, but instead to separate copies of the original object. @author Sun Microsystems, Inc. @see net.jini.core.lookup.ServiceRegistrar @since 1.0
