Method Detail

instantiate

public Expression instantiate(NameSpace ns)
                       throws ParseException

Creates the placeholders for the actuel parameters transfer and the DefaultInstruction for the func invocation.

instantiate in interface ExpressionDescription

toString

public java.lang.String toString()

Description copied from class: java.lang.Object

Convert this Object to a human-readable String. There are no limits placed on how long this String should be or what it should contain. We suggest you make it as intuitive as possible to be able to place it into System.out.println() 55 and such.

It is typical, but not required, to ensure that this method never completes abruptly with a java.lang.RuntimeException.

This method will be called when performing string concatenation with this object. If the result is null, string concatenation will instead use "null".

The default implementation returns getClass().getName() + "@" + Integer.toHexString(hashCode()).
