public void describeTo(Description description)

Implements org.hamcrest.SelfDescribing.describeTo.

Doc from org.hamcrest.SelfDescribing.describeTo.

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:Description

The description to be built or appended to.

public boolean matches(Object arg)

Implements org.hamcrest.Matcher.matches.

Doc from org.hamcrest.Matcher.matches.

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
arg:Object

the object against which the matcher is evaluated.

Returns:boolean

true if item matches, otherwise false.

@Override

public static <T> Matcher<T> not(Matcher<T> matcher)

Creates a matcher that wraps an existing matcher, but inverts the logic by which it will match. For example: 

assertThat(cheese, is(not(equalTo(smelly))))
Parameters
matcher:Matcher<T>

the matcher whose sense should be inverted

notback to summary
public static <T> Matcher<T> not(T value)

A shortcut to the frequently used not(equalTo(x)). For example: 

assertThat(cheese, is(not(smelly)))
instead of: 
assertThat(cheese, is(not(equalTo(smelly))))
Parameters
value:T

the value that any examined object should not equal
