public class IsInstanceOf
Tests whether the value is an instance of a class. Classes of basic types will be converted to the relevant "Object" classes
| Constructor Summary | |

IsInstanceOf(Class<?> expectedClass)
Creates a new instance of IsInstanceOf |

any(Class<T> type)
Creates a matcher that matches when the examined object is an instance of the specified type,
as determined by calling the Class.isInstance(Object) method on that type, passing the
the examined object. |
|
void |
describeTo(Description description)
Generates a description of the object. |

instanceOf(Class<?> type)
Creates a matcher that matches when the examined object is an instance of the specified type,
as determined by calling the Class.isInstance(Object) method on that type, passing the
the examined object. |

type,
as determined by calling the Class.isInstance(Object) method on that type, passing the
the examined object.
The created matcher assumes no relationship between specified type and the examined object.
For example:assertThat(new Canoe(), instanceOf(Paddlable.class));
public static <T> Matcher<T> any(Class<T> type)
type,
as determined by calling the Class.isInstance(Object) method on that type, passing the
the examined object.
The created matcher forces a relationship between specified type and the examined object, and should be
used when it is necessary to make generics conform, for example in the JMock clause
with(any(Thing.class))
assertThat(new Canoe(), instanceOf(Canoe.class));
