Method Summary | ||
---|---|---|
boolean |
check(java.util.List<?> objList)
Determines whether all of the input objects satisfy the query. |
|
boolean |
check(java.lang.Object obj)
Evaluates the query on an object. |
|
java.lang.Object |
evaluate()
Evaluates the query. |
|
java.util.List<?> |
evaluate(java.util.List<?> objList)
Evaluates the query on the input list. |

EvaluationEnvironment<C,O,P,CLS,E> |
getEvaluationEnvironment()
Obtains the evaluation environment that I use to evaluate OCL expressions. |
