endsAfter

public static <T,
R extends DateTemporal>
Predicate<T> endsAfter(Function<T,R> extractor,

Type Parameters:

T - the type of the temporal.

Parameters:

date - the LocalDate

Returns:

isTrue

public static <T> Predicate<T> isTrue(Function<T,Boolean> extractor)

Returns a predicate that checks if the input extractor's return value is equal to Boolean.TRUE.

Type Parameters:

T - the type of the object from which the boolean is extracted

Parameters:

extractor - the extractor to get the boolean from an object

Returns:

the predicate that checks if the input extractor's return value is equal to Boolean.TRUE.

isFalse

public static <T> Predicate<T> isFalse(Function<T,Boolean> extractor)
