构造器详细信息

IsInstanceOf

public IsInstanceOf(Class<?> theClass)

Creates a new instance of IsInstanceOf

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

方法详细信息

matches

public boolean matches(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.

参数:: item - the object against which the matcher is evaluated.
返回:: true if item matches, otherwise false.
另请参见:: 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.

参数:: description - The description to be built or appended to.

instanceOf

public static org.hamcrest.Matcher<Object> instanceOf(Class<?> type)

Is the value an instance of a particular type?
