Constructor Summary

RequestMappingInfo(PatternsRequestCondition patterns, RequestMethodsRequestCondition methods, ParamsRequestCondition params, HeadersRequestCondition headers, ConsumesRequestCondition consumes, ProducesRequestCondition produces, RequestCondition<?> custom)
Creates a new instance with the given request conditions.

RequestMappingInfo(RequestMappingInfo info, RequestCondition<?> customRequestCondition)

Method Summary

RequestMappingInfo	combine(RequestMappingInfo other) Combines "this" request mapping info (i.e.
int	compareTo(RequestMappingInfo other, HttpServletRequest request) Compares "this" info (i.e.
boolean	equals(Object obj)
ConsumesRequestCondition	getConsumesCondition() Returns the "consumes" condition of this RequestMappingInfo; or instance with 0 consumes expressions, never null
RequestCondition<?>	getCustomCondition() Returns the "custom" condition of this RequestMappingInfo; or null
HeadersRequestCondition	getHeadersCondition() Returns the "headers" condition of this RequestMappingInfo; or instance with 0 header expressions, never null
RequestMappingInfo	getMatchingCondition(HttpServletRequest request) Checks if all conditions in this request mapping info match the provided request and returns a potentially new request mapping info with conditions tailored to the current request.

                          RequestCondition<?> custom)

Creates a new instance with the given request conditions.

RequestMappingInfo

public RequestMappingInfo(RequestMappingInfo info,
                          RequestCondition<?> customRequestCondition)

Re-create a RequestMappingInfo with the given custom request condition.

Method Detail

getPatternsCondition

public PatternsRequestCondition getPatternsCondition()

Returns the URL patterns of this RequestMappingInfo; or instance with 0 patterns, never null

getMethodsCondition

public RequestMethodsRequestCondition getMethodsCondition()

Returns the HTTP request methods of this RequestMappingInfo; or instance with 0 request methods, never null

getParamsCondition

public ParamsRequestCondition getParamsCondition()

Returns the "parameters" condition of this RequestMappingInfo; or instance with 0 parameter expressions, never null

getHeadersCondition

public HeadersRequestCondition getHeadersCondition()

Returns the "headers" condition of this RequestMappingInfo; or instance with 0 header expressions, never null

getConsumesCondition

public ConsumesRequestCondition getConsumesCondition()

Returns the "consumes" condition of this RequestMappingInfo; or instance with 0 consumes expressions, never null

getProducesCondition

public ProducesRequestCondition getProducesCondition()

Returns the "produces" condition of this RequestMappingInfo; or instance with 0 produces expressions, never null

getCustomCondition

public RequestCondition<?> getCustomCondition()

Returns the "custom" condition of this RequestMappingInfo; or null

combine

public RequestMappingInfo combine(RequestMappingInfo other)

Combines "this" request mapping info (i.e. the current instance) with another request mapping info instance.

Example: combine type- and method-level request mappings.

Specified by:

combine in interface RequestCondition<RequestMappingInfo>

Parameters:

other - the condition to combine with.

Returns:

a new request mapping info instance; never null

getMatchingCondition

public RequestMappingInfo getMatchingCondition(HttpServletRequest request)

Checks if all conditions in this request mapping info match the provided request and returns a potentially new request mapping info with conditions tailored to the current request.

For example the returned instance may contain the subset of URL patterns that match to the current request, sorted with best matching patterns on top.

Specified by:

getMatchingCondition in interface RequestCondition<RequestMappingInfo>

Returns:

a new instance in case all conditions match; or null otherwise

compareTo

public int compareTo(RequestMappingInfo other,
                     HttpServletRequest request)

Compares "this" info (i.e. the current instance) with another info in the context of a request.

Note: it is assumed both instances have been obtained via getMatchingCondition(HttpServletRequest) to ensure they have conditions with content relevant to current request.

Specified by:

compareTo in interface RequestCondition<RequestMappingInfo>

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()
