extends org.hamcrest.BaseMatcher<java.lang.Object>

Tests whether the value is an instance of a class.

Constructor Summary
`IsInstanceOf(java.lang.Class<?> theClass)` Creates a new instance of IsInstanceOf

Constructor Detail

### IsInstanceOf

    public IsInstanceOf(java.lang.Class<?> theClass)

  Creates a new instance of IsInstanceOf

  Parameters:
    `theClass` - The predicate evaluates to true for instances of this class or one of its subclasses.

Method Detail

### matches

    public boolean matches(java.lang.Object item)

  Description copied from interface: `org.hamcrest.Matcher`
  Evaluates the matcher for argument item.

  This method matches against Object, instead of the generic type T. This is because the caller of the Matcher does not know at runtime what the type is (because of type erasure with Java generics). It is down to the implementations to check the correct type.

  Parameters:
    `item` - the object against which the matcher is evaluated.
  Returns:
    `true` if item matches, otherwise `false`.
  See Also:
    `BaseMatcher`

### describeTo

    public void describeTo(org.hamcrest.Description description)

  Description copied from interface: `org.hamcrest.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 org.hamcrest.Matcher<java.lang.Object> instanceOf(java.lang.Class<?> type)

  Is the value an instance of a particular type?
