Method Detail

evaluateNode

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

Overrides:
evaluateNode in class ASTScalar
Throws:
Exception

shallowCopy

public Expression shallowCopy()
Creates a copy of this expression node, without copying children.

Overrides:
shallowCopy in class ASTScalar

setValue

public void setValue(Object value)

encodeAsEJBQL

public void encodeAsEJBQL(PrintWriter pw,
                          String rootId)
Description copied from class: Expression
