Composite

An SCA composite is used to assemble components in logical groupings. It is the basic unit of composition within an SCA System. An SCA Composite contains a set of Components, Services, References and the Wires that interconnect them. Composites are component implementations in higher-level composites in other words composites can have components that are implemented by composites.

A composite has the following normative characteristics:

  • It defines a boundary for Component visibility. Components may not be directly referenced outside of the composite that contains them.
  • It can be used as a unit of deployment. Composites are used to contribute business services to an SCA system.
Apache Incubator Logo Copyright © 2006, The Apache Software Foundation
Apache Tuscany is an effort undergoing incubation at The Apache Software Foundation (ASF), sponsored by the Web Services PMC. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.
