    Description copied from interface: Matcher
    
    This method simply acts a friendly reminder not to implement Matcher directly and instead extend BaseMatcher. It's easy to ignore JavaDoc, but a bit harder to ignore compile errors .
    
    Specified by:
    
    _dont_implement_Matcher___instead_extend_BaseMatcher_ in interface Matcher<T>
    
    See Also:

  - describeMismatch
```
public void describeMismatch(java.lang.Object item,
                             Description description)
```
    Description copied from interface: Matcher
    
    Generate a description of why the matcher has not accepted the item. The description will be part of a larger description of why a matching failed, so it should be concise. This method assumes that matches(item) is false, but will not check this.
    
    Specified by:
    
    describeMismatch in interface Matcher<T>
    
    Parameters:
    
    item - The item that the Matcher has rejected.
    
    description - The description to be built or appended to.
  - toString
```
public java.lang.String toString()
```
    Overrides:
    
    toString in class java.lang.Object
