Class 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.
