Method Detail

getMethod

public String getMethod()

Description copied from interface: Request

Get the request method, e.g. GET, POST, etc.

Specified by:

getMethod in interface Request

Returns:

the request method

HttpMethod

getFormParameters

public MultivaluedMap<String,String> getFormParameters()

selectVariant

public Variant selectVariant(List<Variant> variants)
                      throws IllegalArgumentException

Description copied from interface: Request

Select the representation variant that best matches the request. More explicit variants are chosen ahead of less explicit ones. A vary header is computed from the supplied list and automatically added to the response.

Specified by:

selectVariant in interface Request

Parameters:

variants - a list of Variant that describe all of the available representation variants.

Returns:

the variant that best matches the request.

Throws:

IllegalArgumentException - if variants is empty or null

See Also:

Variant.VariantListBuilder

convertEtag

public List<EntityTag> convertEtag(List<String> tags)

ifMatch

public Response.ResponseBuilder ifMatch(List<EntityTag> ifMatch,
                                        EntityTag eTag)

ifNoneMatch

public Response.ResponseBuilder ifNoneMatch(List<EntityTag> ifMatch,
                                            EntityTag eTag)

evaluatePreconditions

public Response.ResponseBuilder evaluatePreconditions(EntityTag eTag)

Description copied from interface: Request

Evaluate request preconditions based on the passed in value.

Specified by:

evaluatePreconditions in interface Request

Parameters:

eTag - an ETag for the current state of the resource

Returns:

null if the preconditions are met or a ResponseBuilder set with the appropriate status if the preconditions are not met. A returned ResponseBuilder will include an ETag header set with the value of eTag.

ifModifiedSince

public Response.ResponseBuilder ifModifiedSince(String strDate,
                                                Date lastModified)

ifUnmodifiedSince

public Response.ResponseBuilder ifUnmodifiedSince(String strDate,
                                                  Date lastModified)

evaluatePreconditions

public Response.ResponseBuilder evaluatePreconditions(Date lastModified)

Description copied from interface: Request

Evaluate request preconditions based on the passed in value.

Specified by:

evaluatePreconditions in interface Request

Parameters:

lastModified - a date that specifies the modification date of the resource

Returns:

null if the preconditions are met or a ResponseBuilder set with the appropriate status if the preconditions are not met.

evaluatePreconditions

public Response.ResponseBuilder evaluatePreconditions(Date lastModified,
                                                      EntityTag eTag)

Description copied from interface: Request

Evaluate request preconditions based on the passed in value.

Specified by:

evaluatePreconditions in interface Request

Parameters:

lastModified - a date that specifies the modification date of the resource

eTag - an ETag for the current state of the resource

Returns:

null if the preconditions are met or a ResponseBuilder set with the appropriate status if the preconditions are not met. A returned ResponseBuilder will include an ETag header set with the value of eTag.

evaluatePreconditions

public Response.ResponseBuilder evaluatePreconditions()

Description copied from interface: Request

Evaluate request preconditions for a resource that does not currently exist. The primary use of this method is to support the If-Match: * and If-None-Match: * preconditions.

Note that both preconditions If-None-Match: * and If-None-Match: something will always be considered to have been met and it is the applications responsibility to enforce any additional method-specific semantics. E.g. a PUT on a resource that does not exist might succeed whereas a GET on a resource that does not exist would likely result in a 404 response. It would be the responsibility of the application to generate the 404 response.

Specified by:

evaluatePreconditions in interface Request

Returns:

null if the preconditions are met or a ResponseBuilder set with the appropriate status if the preconditions are not met.
