  - test
```
boolean test(Request request)
```
    Evaluates this predicate on the given request.
    
    Parameters:
    
    request - the request to match against
    
    Returns:
    
    true if the request matches the predicate; false otherwise
  - and
```
default RequestPredicate and(RequestPredicate other)
```
    Returns a composed request predicate that tests against both this predicate AND the other predicate. When evaluating the composed predicate, if this predicate is false, then the other predicate is not evaluated.
    
    Parameters:
    
    other - a predicate that will be logically-ANDed with this predicate
    
    Returns:
    
    a predicate composed of this predicate AND the other predicate
  - negate
```
default RequestPredicate negate()
```
    Return a predicate that represents the logical negation of this predicate.
    
    Returns:
    
    a predicate that represents the logical negation of this predicate
  - or
```
default RequestPredicate or(RequestPredicate other)
```
    Returns a composed request predicate that tests against both this predicate OR the other predicate. When evaluating the composed predicate, if this predicate is true, then the other predicate is not evaluated.
    
    Parameters:
    
    other - a predicate that will be logically-ORed with this predicate
    
    Returns:
