com.bea.p13n.expression.internal.ComplexExpressionImpl
com.bea.p13n.expression.operator.Operator
com.bea.p13n.expression.operator.Variable
public final class Variable
Implementation of the Variable operator. The variable operator defines a place-holder for a variable that will be substituted during unification.
Input 1: A String (or Expression returning a String) that is the name of the variable.
Input 2: A Class (or Expression returning a Class) that is the type of the variable.
