Component Conngurer: a Design Pattern for Component-based Connguration

Factory [Gamma 95]class ComponentGenerator represents a use of the AbstractFactory pattern. Classes derived from ComponentGenerator will encapsulate thegeneration of concrete ReconfComponent, LPlug and RPlug objects,Factory Method [Gamma 95]method newCompGen in class ReconfComponent representa use of the Factory Method pattern.Distributed Proxy [Silva 97] RPlug and LPlug classes can make use of the DistributedProxy pattern as a mean of supporting application partitioning.Service Con gurator [Jain 96] this pattern deals with service con guration intocomponents. It aims at internal server component con guration, addition, change anddeletion of component services, as opposed to inter-component con guration with addition,change and deletion of server components.Pipes and Filters [Buschmann 96] this pattern again deals with the internal con gurationof pipeline based components.Callback [Berczuk 95] the pattern for the separation of assembly and processing canprovide a way for component interaction. The structure of the pattern foresees theexistence of some dynamic con guration allowing the connection establishment betweencomponents.Broker [Buschmann 96] the existence of aNameManager class in the proposed pattern canbe related in some way to the broker pattern. The NameManager is used as a repositoryof available Names and locations used to establish communication between components.AcknowledgmentsThe authors would like to thank Steve Berczuk for his valuable suggestions during theshepherding process.References[Belissard 96] Luc Belissard and Michel Riveill.
