Class InferenceManager

java.lang.Object
  LBJ2.infer.InferenceManager

public class InferenceManager
extends java.lang.Object

The inference manager is a cache of Inference objects accessed via their names and head objects. However, only one Inference object is stored per Inference class. For example, if the LBJ source file contains the following two inferences:

inference Foo head MyClass { ... }
inference Bar head MyClass { ... }

then this InferenceManager will store a maximum of one Foo object and one Bar object.
