test
public boolean test(T value)
- Specified by:
testin classBoundPredicate<T>
-
isEquivalentTo
public boolean isEquivalentTo(Expression expr)
Description copied from interface:ExpressionReturns whether this expression will accept the same values as another.If this returns true, the expressions are guaranteed to return the same evaluation for the same input. However, if this returns false the expressions may return the same evaluation for the same input. That is, expressions may be equivalent even if this returns false.
For best results, rewrite not and bind expressions before calling this method.
- Parameters:
expr- another expression- Returns:
