Class RBResourceContext

java.lang.Object
  com.ibm.etools.iseries.remotebuild.RBResourceContext

public class RBResourceContext
extends Object

An RBResourceContext provides a means of caching references to RBResources by their model resource. The RBResource hierarchy uses this to ensure that the resources that are located through a context preserve object identity. If an RBResourceContext is not used, then, for example, the RBProject returned by two successive calls to getProject() on the same resource will return different object instances for the RBProject. If the resource has an associated RBResourceContext, then these two results will be the same instance.

An operation that takes a selection of AbstractISeriesResources and creates RBResources from them should establish a context at the beginning of the operation, use it for resolution, and then discard it at the end of the operation.
