org.hamcrest.core
Class Is<T>

java.lang.Object
  org.hamcrest.BaseMatcher<T>
      org.hamcrest.core.Is<T>

All Implemented Interfaces:

org.hamcrest.Matcher<T>, org.hamcrest.SelfDescribing

public class Is<T>
extends org.hamcrest.BaseMatcher<T>

Decorates another Matcher, retaining the behavior but allowing tests to be slightly more expressive. eg. assertThat(cheese, equalTo(smelly)) vs assertThat(cheese, is(equalTo(smelly)))

Constructor Summary

Is(org.hamcrest.Matcher<T> matcher)

Method Summary

void	describeTo(org.hamcrest.Description description)
static org.hamcrest.Matcher<java.lang.Object>	is(java.lang.Class<?> type) This is a shortcut to the frequently used is(instanceOf(SomeClass.class)).
static <T> org.hamcrest.Matcher<T>	is(org.hamcrest.Matcher<T> matcher) Decorates another Matcher, retaining the behavior but allowing tests to be slightly more expressive.
static <T> org.hamcrest.Matcher<T>	is(T value) This is a shortcut to the frequently used is(equalTo(x)).
boolean	matches(java.lang.Object arg)

is

public static <T> org.hamcrest.Matcher<T> is(org.hamcrest.Matcher<T> matcher)
