Method Summary

All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`reactor.core.publisher.Mono<HandlerMethod>`	`getHandlerInternal(ServerWebExchange exchange)`	Look up a handler method for the given request.
`protected Comparator<RequestMappingInfo>`	`getMappingComparator(ServerWebExchange exchange)`	Provide a Comparator to sort RequestMappingInfos matched to a request.
`protected RequestMappingInfo`	`getMatchingMapping(RequestMappingInfo info, ServerWebExchange exchange)`	Check if the given RequestMappingInfo matches the current request and return a (potentially new) instance with conditions that match the current request -- for example with a subset of URL patterns.
`protected void`	`handleMatch(RequestMappingInfo info, HandlerMethod handlerMethod, ServerWebExchange exchange)`	Expose URI template variables, matrix variables, and producible media types in the request.
`protected HandlerMethod`	`handleNoMatch(Set<RequestMappingInfo> infos, ServerWebExchange exchange)`	Iterate all RequestMappingInfos once again, look if any match by URL at least and raise exceptions accordingly.

public RequestMappingInfoHandlerMapping()
```
- Method Detail
  - getMatchingMapping
```
protected RequestMappingInfo getMatchingMapping(RequestMappingInfo info,
                                                ServerWebExchange exchange)
```
    Check if the given RequestMappingInfo matches the current request and return a (potentially new) instance with conditions that match the current request -- for example with a subset of URL patterns.
    Specified by:
    getMatchingMapping in class AbstractHandlerMethodMapping<RequestMappingInfo>
    Parameters:
    info - the mapping to get a match for
    exchange - the current exchange
    Returns:
    an info in case of a match; or null otherwise.
  - getMappingComparator
```
protected Comparator<RequestMappingInfo> getMappingComparator(ServerWebExchange exchange)
```
    Provide a Comparator to sort RequestMappingInfos matched to a request.
    Specified by:
    getMappingComparator in class AbstractHandlerMethodMapping<RequestMappingInfo>
    Parameters:
    exchange - the current exchange
    Returns:
    the comparator (never null)
  - getHandlerInternal
```
public reactor.core.publisher.Mono<HandlerMethod> getHandlerInternal(ServerWebExchange exchange)
```
    Description copied from class: AbstractHandlerMethodMapping
    Look up a handler method for the given request.
    Overrides:
    getHandlerInternal in class AbstractHandlerMethodMapping<RequestMappingInfo>
    Parameters:
    exchange - the current exchange
    Returns:
    Mono for the matching handler, if any
  - handleMatch
```
protected void handleMatch(RequestMappingInfo info,
                           HandlerMethod handlerMethod,
                           ServerWebExchange exchange)
```
    Expose URI template variables, matrix variables, and producible media types in the request.
    Overrides:
    handleMatch in class AbstractHandlerMethodMapping<RequestMappingInfo>
    Parameters:
    info - the matching mapping
    handlerMethod - the matching method
    exchange - the current exchange
    See Also:
    HandlerMapping.URI_TEMPLATE_VARIABLES_ATTRIBUTE, HandlerMapping.MATRIX_VARIABLES_ATTRIBUTE, HandlerMapping.PRODUCIBLE_MEDIA_TYPES_ATTRIBUTE
  - handleNoMatch
```
protected HandlerMethod handleNoMatch(Set<RequestMappingInfo> infos,
                                      ServerWebExchange exchange)
                               throws Exception
```
    Iterate all RequestMappingInfos once again, look if any match by URL at least and raise exceptions accordingly.
    Overrides:
    handleNoMatch in class AbstractHandlerMethodMapping<RequestMappingInfo>
    Parameters:
    infos - all registered mappings
    exchange - the current exchange
    Returns:
    an alternative HandlerMethod or null
    Throws:
    MethodNotAllowedException - for matches by URL but not by HTTP method
    UnsupportedMediaTypeStatusException - if there are matches by URL and HTTP method but not by consumable media types
    NotAcceptableStatusException - if there are matches by URL and HTTP method but not by producible media types
    ServerWebInputException - if there are matches by URL and HTTP method but not by query parameter conditions
    Exception - provides details that can be translated into an error status code
