Method Summary

Modifier and Type	Method and Description
public default CheckedPredicate<T>	Returns: A new CheckedPredicate. negate() Negates this predicate.
public static < type of values that are tested by the predicate T> CheckedPredicate<T>	Returns: a new `CheckedPredicate` of(CheckedPredicate<T> (typically) a method reference, e.g. `Type::method` methodReference) Creates a `CheckedPredicate`.
public boolean	Returns: `true` if the input argument matches the predicate, otherwise `false` test(T the input argument t) Evaluates this predicate on the given argument.
public default Predicate<T>	Returns: a new `Predicate` that throws a `Throwable`. unchecked() Returns an unchecked `Predicate` that will sneaky throw if an exceptions occurs when testing a value.
