Method Detail

evaluate

public boolean evaluate(IExecutionContext ctxt,
                        IEvaluationCondition condition)
                 throws MConditionEvaluationException

Description copied from interface: IEvaluationOperator

Evaluate result for this operator.

Specified by:

evaluate in interface IEvaluationOperator

Overrides:

evaluate in class EQ

Throws:

MConditionEvaluationException

getNegated

public IEvaluationOperator getNegated()

Description copied from interface: IEvaluationOperator

Returns a new instance instance of Evaluation operator, allowing to negate the operands.
For example, "a < b" negated gives "a >= b", and is strictly equivalent to "! (a < b)". This feature is used by optimization process, so a null result by default while the operator could be negated might lead to less efficient performance.

Specified by:

getNegated in interface IEvaluationOperator

Overrides:

getNegated in class EQ

Returns:

new operator instance or null if negation is not possible.

getRepresentation

public String getRepresentation()

Description copied from interface: IEvaluationOperator

String representation for human read

Specified by:

getRepresentation in interface IEvaluationOperator

Overrides:

getRepresentation in class EQ

getImplementationId

public String getImplementationId()

Description copied from interface: IAddon

Unique addon implementation ID. In case of conflict, an Class Initialization error will be raised.

Specified by:

getImplementationId in interface IAddon

Overrides:

getImplementationId in class EQ
