Examples with Resource org.osgi.resource.Resource used on opensource projects

Example 1 with Resource

use of org.osgi.resource.Resource in project aries by apache.

the class AriesSubsystemTest method testAddRequirementsKeepsEdgesOtherThanParentChild.

/*
	 * The region copy process when adding additional requirements should
	 * keep all edges, not just the ones running between parent and child. This
	 * is of particular concern with regard to the connections all subsystem
	 * regions have with the root region to allow the subsystem services
	 * through. However, it may also be of concern if the region digraph is
	 * modified outside of the subsystems API.
