Examples of com.opengamma.engine.target.ComputationTargetReference

com.opengamma.engine.target.ComputationTargetReference
A reference to a particular computation target that will be resolved later to a real target. The reference may be "strict" and refer to a specific object or concept by {@link UniqueId} or "loose"and refer to it by a broader identifier bundle that must first be resolved.
