Direct Known Subclasses:

EdgeAnnotationStrategy, NoAnnotationStrategy, NodeAnnotationStrategy

public abstract class AnnotationStrategy
extends java.lang.Object

Each class serving as AnnotationOwner gets an AnnotationStrategy saying how the Annotations should behave when the AnnotationOwner changes its position (e.g. move in parallel).
