public class VariableBinding
Implementation of the VariableBinding operator. The variable-binding operator gives a conditional operator which supplies a place for binding a variable that will be substituted during unification. This variable can then be used in a rule action.

Expression
.
Because the sub-expressions within the Expression
are
typically arguments or operands, some type validation is performed
by examining the class types of the sub-expressions against the
Expression
's parameter signature.
