Class CustomMatcher<T>

java.lang.Object
org.hamcrest.BaseMatcher<T>
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. See CustomTypeSafeMatcher for a type safe variant of this class that you probably want to use.
