public Operand compileExpression() throws ExpressionException, MalformedExpressionException
Checks the semantic integrity of an expression. It checks that all types are compatible and prepare the expression to be evaluable.It also creates buffers where stores the result. Notes that when evaluating there is no creation of new objects. This method change the state of this expression object, it will be evaluable and not modifiable.
- Specified by:
- compileExpression in interface Expression
- Throws:
