Method Detail

getPreviousLinkFromDatasetWithHeaders

public java.lang.String getPreviousLinkFromDatasetWithHeaders(DatasetResponseWithStatusCodeAndHeaders datasetWithHeaders)

extract the previous link (in case won node had more data than could be sent or was requested) from http response headers

Parameters:

datasetWithHeaders -

Returns:

the previous link to more data on the node or null if the link header does not exist

getDatasetWithHeadersForResource

public DatasetResponseWithStatusCodeAndHeaders getDatasetWithHeadersForResource(java.net.URI resource,
                                                                                org.springframework.http.HttpHeaders httpHeaders)

get a dataset with headers. this methods can be used in combination with getPreviousLinkFromDatasetWithHeaders in case links to previous pages of data from the won node should be checked too

Parameters:

resource - uri of the resource to request

Returns:

dataset including http response headers

getDataForResource

public org.apache.jena.query.Dataset getDataForResource(java.net.URI resource)

Description copied from interface: LinkedDataSource

Obtains resource description of the resource identified by the given URI

Specified by:

getDataForResource in interface LinkedDataSource

Returns:

resource description as Dataset, or empty Dataset if not a valid URI or not found
