Description

Interface Summary

GroupInterface	This is the magic interface, signalling the compiler to generate stub and skeleton code.
GroupProtocol	Constants, placed in an interface to allow for easy access.

Class Summary

BinomialCombiner	The BinomialCombiner class serves as a base class for user-defined binomial reply combiners.
BinomialInvocationCombiner	The BinomialInvocationCombiner class serves as a base class for user-defined binomial invocation combiners.
CombinedInvocation	The CombinedInvocation class must be used whenever a group method must be configured using a combined invocation scheme.
CombinedInvocationInfo	The CombinedInvocationInfo class is used to collect some information about a combined invocation.
CombineReply	The CombineReply class must be used to configure a group method with a combined reply.
DiscardReply	The DiscardReply class must be used when configuring a group method to discard its result.
FlatCombiner	The FlatCombiner class serves as a base class for user-defined result flat-combiners.
FlatInvocationCombiner	The FlatInvocationCombiner class provides a base class for user-defined flat invocation combiners.
Forwarder	The Forwarder class serves as a base class for user-defined forwarders.
ForwardReply	The ForwardReply class must be used when configuring a group method to forward all replies to a Forwarder object.
Group	The Group class takes care of the startup, and has methods to create, join, lookup, and exit a group.
GroupInvocation	The GroupInvocation class is to be used when configuring a group method to be invoked on all members of the group.
GroupMember	To be part of a group, an object must implement the GroupInterface and extent the GroupMember class.
GroupMessage	The GroupMessage class is a container class for keeping replies around until they can be processed.
GroupMethod	A GroupMethod object represents a method of a specific group reference.
GroupSkeleton	The GroupSkeleton class serves as a base class for generated skeletons.
GroupStub	The GroupStub class provides a base class for generated stubs.
InvocationScheme	The InvocationScheme class provides a base class for all invocation schemes.
ParameterVector	The ParameterVector class provides a base class for generated parameter vector classes, specific for a group method.
PersonalizedInvocation	The PersonalizedInvocation class must be used to configure a group method for personalized invocations.
Personalizer	The Personalizer class provides a base class for parameter personalizers.
PersonalizeReply	The PersonalizeReply class must be used when configuring a group method to have a personalized reply scheme.
ReplyPersonalizer	The ReplyPersonalizer class can be extended by the user to create a specific reply personalizer.
ReplyScheme	Class ReplyScheme is the base class for all reply schemes.
ReturnReply	The ReturnReply class must be used to configure a group method that returns a single reply, from the indicated group member.
SingleInvocation	The SingleInvocation class must be used to configure a group method to a single invocation.

Exception Summary

ConfigurationException

The ConfigurationException class describes exceptions caused by illegal group method configurations.

Package ibis.gmi Description

The GMI (Group Method Invocation) package implements group communication using method invocations.

The GMI model generalizes the RMI model in three ways. First, a reference (stub) can be used to refer to a group of objects instead of a single object. Second, GMI has several ways of forwarding method invocations and dealing with the replies. For instance, GMI allows the user to express broadcast and asynchronous communication. Third, GMI allows the programmer to configure a group reference at run time to use specific forwarding and result-handling schemes. Each method in a group reference can be configured separately, and different forwarding and result-handling schemes can be combined.
