evaluateNode
protected Object evaluateNode(Object o)
                       throws Exception
- Description copied from class: SimpleNode
- Evaluates itself with object, pushing result on the stack.

- Specified by:
- evaluateNodein class- SimpleNode
 
- 
- Throws:
- Exception

shallowCopy
public Expression shallowCopy()
- Creates a copy of this expression node, without copying children.
 
- 
- Specified by:
- shallowCopyin class- Expression

encodeAsString
public void encodeAsString(PrintWriter pw)
- Description copied from class: Expression
- Stores a String representation of Expression using a provided PrintWriter.
 
- 
- Overrides:
- encodeAsStringin class- SimpleNode
