Example 3 with AriesSubsystem

use of org.apache.aries.subsystem.AriesSubsystem in project aries by apache.

the class AriesSubsystemTest method testAddRequirementWithVisibleBundleNamespace.

/*
	 * Aries Subsystems uses Equinox Region Digraph as its isolation engine.

	 * everything a bundle offers. This test ensures that a correctly formatted
	 * requirement in that namespace works as expected.

Example 4 with AriesSubsystem

use of org.apache.aries.subsystem.AriesSubsystem 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
