Method Details

isNegated

public static boolean isNegated(EvaluationContext context)

Indicates whether the current Condition is being negated.

getNegationCount

public static int getNegationCount(EvaluationContext context)

Returns the number of "Not"s that have been evaluated in the current evaluation process. For example, when(Not.any(MyCondition)) would have a "NotCount" of "1" during the evaluation of "MyCondition". when(Not.any(Not.any(MyCondition))) would have a "NotCount" of "2" during the evaluation of "MyCondition". This is useful for conditions that may have side effects, as they will know whether or not their condition is being negated.

create

public static ConditionBuilder create()

Return a new DefaultConditionBuilder that evaluates to True when #evaluate(Rewrite, EvaluationContext) is invoked.

wrap

public static ConditionBuilder wrap(Condition condition)

Wrap a given Condition as a new DefaultConditionBuilder that evaluates the the original Condition when #evaluate(Rewrite, EvaluationContext) is invoked.
