Method Detail

clone

public java.lang.Object clone(java.lang.Object clone,
                              java.util.Map obj2clone)
                       throws java.lang.CloneNotSupportedException
Description copied from interface: org.objectweb.medor.clone.api.Cloneable
Clone the current object.

Specified by:
clone in interface org.objectweb.medor.clone.api.Cloneable
Overrides:
clone in class BasicOperator
Throws:
java.lang.CloneNotSupportedException

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

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

getResult

public Operand getResult()
                  throws java.lang.IllegalStateException
Throws:
java.lang.IllegalStateException

evaluate

public Operand evaluate(ParameterOperand[] values,
                        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:
values - a list of ParameterOperand
o - the input Object from which values are taken for the evaluation
Returns:
an Operand containing the result of the evaluation
Throws:
ExpressionException
