Constructor Detail

BasicUnaryArithmeticOperator

public BasicUnaryArithmeticOperator()
Method Detail

getType

public PType getType()
Description copied from interface: Expression
It gets the result type of this expression

Specified by:
getType in interface Expression
Overrides:
getType in class BasicUnaryOperator
Returns:
a PType object

evaluate

public void evaluate(ParameterOperand[] pos,
                     Tuple t)
              throws MedorException,
                     java.lang.IllegalStateException
Description copied from interface: Expression
It evaluates the expression tree and puts the result into the operand result.

Specified by:
evaluate in interface Expression
Specified by:
evaluate in class BasicUnaryOperator
Parameters:
pos - a list of ParameterOperand
t - Tuple
Throws:
java.lang.IllegalStateException - if this expression is not compiled.
MedorException - if evaluation error

compileExpression

public void compileExpression()
                       throws TypingException,
                              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:
compileExpression in interface Expression
Throws:
MalformedExpressionException - if syntax error
TypingException - when incompatible types error occures.
