Methods

Modifier and Type	Method and Description
static <T> Matcher<T>	any(Class<T> type) Is the value an instance of a particular type? Use this version to make generics conform, for example in the JMock clause with(any(Thing.class))
void	describeTo(Description description) Generates a description of the object.
static <T> Matcher<T>	instanceOf(Class<?> type) Is the value an instance of a particular type? This version assumes no relationship between the required type and the signature of the method that sets it up, for example in assertThat(anObject, instanceOf(Thing.class));

Constructor Detail

IsInstanceOf

public IsInstanceOf(Class<?> expectedClass)

Creates a new instance of IsInstanceOf

Parameters:

expectedClass - The predicate evaluates to true for instances of this class or one of its subclasses.

Method Detail

matches

protected boolean matches(Object item,
              Description mismatchDescription)

Specified by:

matches in class DiagnosingMatcher<Object>

describeTo

public void describeTo(Description description)

Description copied from interface: SelfDescribing

Generates a description of the object. The description may be part of a a description of a larger object of which this is just a component, so it should be worded appropriately.

Parameters:

description - The description to be built or appended to.

instanceOf

public static <T> Matcher<T> instanceOf(Class<?> type)

Is the value an instance of a particular type? This version assumes no relationship between the required type and the signature of the method that sets it up, for example in assertThat(anObject, instanceOf(Thing.class));

any

public static <T> Matcher<T> any(Class<T> type)

Is the value an instance of a particular type? Use this version to make generics conform, for example in the JMock clause with(any(Thing.class))
