```
void method(Set<HttpMethod> methods)
```
    Receive notification of an HTTP method predicate.
    Parameters:
    methods - the HTTP methods that make up the predicate
    See Also:
    RequestPredicates.method(HttpMethod)
  - path
```
void path(String pattern)
```
    Receive notification of an path predicate.
    Parameters:
    pattern - the path pattern that makes up the predicate
    See Also:
    RequestPredicates.path(String)
  - pathExtension
```
void pathExtension(String extension)
```
    Receive notification of an path extension predicate.
    Parameters:
    extension - the path extension that makes up the predicate
    See Also:
    RequestPredicates.pathExtension(String)
  - header
```
void header(String name,
            String value)
```
    Receive notification of an HTTP header predicate.
    Parameters:
    name - the name of the HTTP header to check
    value - the desired value of the HTTP header
    See Also:
    RequestPredicates.headers(Predicate), RequestPredicates.contentType(MediaType...), RequestPredicates.accept(MediaType...)
  - param
```
void param(String name,
           String value)
```
    Receive notification of a parameter predicate.
    Parameters:
    name - the name of the parameter
    value - the desired value of the parameter
    See Also:
    RequestPredicates.param(String, String)
  - startAnd
```
void startAnd()
```
    Receive first notification of a logical AND predicate. The first subsequent notification will contain the left-hand side of the AND-predicate; followed by and(), followed by the right-hand side, followed by endAnd().
    See Also:
    RequestPredicate.and(RequestPredicate)
  - and
```
void and()
```
    Receive "middle" notification of a logical AND predicate. The following notification contains the right-hand side, followed by endAnd().
    See Also:
    RequestPredicate.and(RequestPredicate)
  - endAnd
```
void endAnd()
```
    Receive last notification of a logical AND predicate.
    See Also:
    RequestPredicate.and(RequestPredicate)
  - startOr
```
void startOr()
```
    Receive first notification of a logical OR predicate. The first subsequent notification will contain the left-hand side of the OR-predicate; the second notification contains the right-hand side, followed by endOr().
    See Also:
    RequestPredicate.or(RequestPredicate)
  - or
```
void or()
```
    Receive "middle" notification of a logical OR predicate. The following notification contains the right-hand side, followed by endOr().
    See Also:
    RequestPredicate.or(RequestPredicate)
  - endOr
```
void endOr()
```
    Receive last notification of a logical OR predicate.
    See Also:
    RequestPredicate.or(RequestPredicate)
  - startNegate
```
void startNegate()
```
    Receive first notification of a negated predicate. The first subsequent notification will contain the negated predicated, followed by endNegate().
    See Also:
    RequestPredicate.negate()
  - endNegate
```
void endNegate()
```
    Receive last notification of a negated predicate.
    See Also:
    RequestPredicate.negate()
  - unknown
```
void unknown(RequestPredicate predicate)
```
    Receive first notification of an unknown predicate.
