public NullMatcher()

Method Detail

matches

public boolean matches(java.lang.Object o)

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:

o - the object against which the matcher is evaluated.

Returns:

true if item matches, otherwise false.

describeTo

public void describeTo(org.hamcrest.Description description)

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.
