compileExpression
public Operand compileExpression()
throws ExpressionException,
MalformedExpressionException
- Description copied from interface:
Expression
- 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:

in interface Expression
- Throws:
MalformedExpressionException
- if syntax error
