public interface Predicate<T>

This interface was deprecated in API level 26.
Use java.util.function.Predicate instead. This must not be used outside frameworks/base/test-runner.

A Predicate can determine a true or false value for any input of its parameterized type. For example, a RegexPredicate might implement Predicate<String>, and return true for any String that matches its given regular expression.

Implementors of Predicate which may cause side effects upon evaluation are strongly encouraged to state this fact clearly in their API documentation.
