public Sqrt(Expression e)
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.
- Specified by:
evaluate
in interface Expression
- 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.
- Specified by:
compileExpression
in interface Expression
- Throws:
MalformedExpressionException
- if syntax error
ExpressionException
getOperatorString
public java.lang.String getOperatorString()
- Description copied from interface:
Operator
- Returns the String representing the operator in Java
- Specified by:
getOperatorString
in interface Operator
- Returns:
- the String representing the operator in Java
