java.lang.Object com.bea.p13n.expression.internal.ComplexExpressionImpl com.bea.p13n.expression.operator.Operator com.bea.p13n.expression.operator.ClassForName
Implementation of the ClassForName operator. Returns
an newly constructed object by invoking a specified constructor.
Input 1: A String object (or expression that evaluates to a String) that
defines the class name for the Class instance to be retrieved.
Returns: A Class instance for the named class.

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.
