accept

public java.lang.Object accept(Visitor v)

Description copied from interface: Visitable

A proper accept() implementation should call one of the visitXXX() methods on the Visitor.

Specified by:

accept in interface Visitable

Parameters:

Returns:

whatever the invoked Visitor method returns.

findVariableDefinitions

public void findVariableDefinitions(int startIndex,
                                    java.util.Hashtable bindingsSoFar,

                             throws JessException

The argument could be a nested group -- a (NOT (AND)). In that case, the indexes used for pattern binding should start with the normal CE index and increment from there, but without affecting the "size" of this LHS.These indexes will be used off on a "branch" of the Rete network.

Specified by:

findVariableDefinitions in interface jess.ConditionalElementX

Throws:

JessException
