public static Matcher<T> of<T>(Predicate<T> matcher)

public static Matcher<T> of<T>(Predicate<T> matcher, Object object)

public static Matcher<T> of<T>(Predicate<T> matcher, String characteristic)

Creates a Matcher with the given Characteristic

public Matcher<T> or(Matcher<T> other)

Returns a new matcher that logically combines the current matcher with the given matcher using the logical or operator.

public Predicate<U> predicate<U extends T>()
