Package net.jini.space

JavaSpaces servers provide a place on the network, a space, for clients to store and exchange objects.

Interface Summary

Interface	Description
JavaSpace	This interface is implemented by servers that export a JavaSpaces technology service.
JavaSpace05	The JavaSpace05 interface extends the JavaSpace interface to provide methods that allow clients to perform batch operations on the space (which are generally more efficient than performing an equivalent set of singleton operations) and to more easily develop applications where a given Entry needs to be read by multiple clients.
MatchSet	A collection of Entry instances to be incrementally returned from a JavaSpaces service.

Class Summary

Class	Description
AvailabilityEvent	A RemoteEvent marking the transition of an Entry from unavailable to available.

Exception Summary

Exception	Description
InternalSpaceException	This exception denotes a problem with the local implementation of the JavaSpace interface.

Package net.jini.space Description

JavaSpaces servers provide a place on the network, a space, for clients to store and exchange objects. Sets of processes in a distributed system can coordinate their actions by flowing objects in and out of the space. Because these processes interact via the space they can be decoupled from each other. The basic JavaSpace interface allows objects, called entries to be copied into, removed from, and/or non-destructively copied out of the space - optionally using Jini technology-based transactions.

The basic JavaSpace interface is specified in the JavaSpaces Service Specification.

The JavaSpace05 interface extends the JavaSpace interface to provide methods that allow clients to perform batch operations on the space (which are generally more efficient than performing an equivalent set of singleton operations) and to more easily develop applications where a given Entry needs to be read by multiple clients. Implementations of the JavaSpace interface are not required to implement this interface.
