evaluate
public Operand evaluate(ParameterOperand[] pos,
java.lang.Object o)
throws ExpressionException
- Description copied from interface:
Expression
- It evaluates the expression tree and puts the result into the operand
result.
- Parameters:
pos
- a list of ParameterOperando
- the input Object from which values are taken for the
evaluation
- Returns:
- an Operand containing the result of the evaluation
- Throws:
ExpressionException
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.
- Throws:
MalformedExpressionException
- if syntax error
ExpressionException
