Class CustomMatcher<T>

  extended by org.hamcrest.BaseMatcher<T>
      extended by org.hamcrest.CustomMatcher<T>
Type Parameters:
T - The type of object being matched.
All Implemented Interfaces:
Matcher<T>, SelfDescribing

public abstract class CustomMatcher<T>
extends BaseMatcher<T>

Utility class for writing one off matchers. For example:

 Matcher<String> aNonEmptyString = new CustomMatcher<String>("a non empty string") {
   public boolean matches(Object object) {
     return ((object instanceof String) && !((String) object).isEmpty();

This class is designed for scenarios where an anonymous inner class matcher makes sense. It should not be used by API designers implementing matchers.
