This view requires a trace containing object reference information, as described in Tracing Considerations . The Start with menu provides a list from which you choose a base set of objects. Squares represent objects, each colored uniquely by class. A diamond represents a class object. Arrows between nodes denote one or more references between instances.
Arrows run right to left by default.
Not all references are shown at once. Objects cascade from left to right as you reveal more and more references. Clicking on this box will expand the tree of references rightward, assuming there are further references. A blue upward-pointing arrow identifies a repetition of the same node. Clicking on this arrow will produce a long blue arrow leading to another occurrence of the same node.
