Class StateWire

org.eclipse.osgi.service.resolver.StateWire

public class StateWire
extends Object

A state wire represents a decision made by a resolver to wire a requirement to a capability. There are 4 parts to a state wire.

• The requirement which may have been specified by a host bundle or one of its attached fragments.
• The host bundle which is associated with the requirement. There are cases where the host bundle may not be the same as the bundle which declared the requirement. For example, if a fragment specifies additional requirements.
• The capability which may have been specified by a host bundle or one of its attached fragments.
• The host bundle which is associated with the capability. There are cases where the host bundle may not be the same as the bundle which declared the capability. For example, if a fragment specifies additional capabilities.
