Field Detail

module

private final RELAXModule module

traversalStack

private final java.util.Stack traversalStack

traversal stack. This object keeps track of how hedgeRules are visited so that detailed error message can be provided when an error is found. Say if you start from hr1, hr1 refers hr2, hr2 refers hr3, and hr3 has a reference to the other module, this stack is {hr1,hr2,hr3} when an error is found.
