Method Details

mapResponses

public NodeResponse mapResponses(URI uri,
 String httpMethod,
 Set<NodeResponse> nodeResponses,
 boolean merge)

Description copied from interface: HttpResponseMapper

Maps the responses from all nodes in the cluster to a single NodeResponse object that is appropriate to respond with

Specified by:

mapResponses in interface HttpResponseMapper

Parameters:

uri - the URI of the web request that was made

httpMethod - the HTTP Method that was used when making the request

nodeResponses - the responses received from the individual nodes

Returns:

a single NodeResponse that represents the response that should be returned to the user/client

getProblematicNodeResponses

public Set<NodeResponse> getProblematicNodeResponses(Set<NodeResponse> allResponses)

Description copied from interface: HttpResponseMapper

Returns a subset (or equal set) of the given Node Responses, such that all of those returned are the responses that indicate that the node was unable to fulfill the request

Specified by:

getProblematicNodeResponses in interface HttpResponseMapper

Parameters:

allResponses - the responses to filter

Returns:

a subset (or equal set) of the given Node Responses, such that all of those returned are the responses that indicate that the node was unable to fulfill the request

isResponseInterpreted

public boolean isResponseInterpreted(URI uri,
 String httpMethod)

Description copied from interface: HttpResponseMapper

Indicates whether or not the responses from nodes for the given URI invalid input: '&' HTTP method must be interpreted in order to merge them

Specified by:

isResponseInterpreted in interface HttpResponseMapper

Parameters:

uri - the URI of the request

httpMethod - the HTTP Method of the request

Returns:

true if the response must be interpreted, false otherwise

 String httpMethod)

hasSuccessfulResponse

private boolean hasSuccessfulResponse(Set<NodeResponse> allResponses)
