Method Detail

write

public void write(OutputStream out,
                  SolrQueryRequest req,
                  SolrQueryResponse response)
           throws IOException

Description copied from interface: BinaryQueryResponseWriter

Use it to write the response in a binary format

Specified by:

write in interface BinaryQueryResponseWriter

Throws:

IOException

write

public void write(Writer writer,
                  SolrQueryRequest request,
                  SolrQueryResponse response)
           throws IOException

Description copied from interface: QueryResponseWriter

Write a SolrQueryResponse, this method must be thread save.

Information about the request (in particular: formatting options) may be obtained from req but the dominant source of information should be rsp.

There are no mandatory actions that write must perform. An empty write implementation would fulfill all interface obligations.

Specified by:

write in interface QueryResponseWriter

Throws:

IOException

getContentType

public String getContentType(SolrQueryRequest request,
                             SolrQueryResponse response)

Description copied from interface: QueryResponseWriter

Return the applicable Content Type for a request, this method must be thread safe.

QueryResponseWriter's must implement this method to return a valid HTTP Content-Type header for the request, that will logically correspond with the output produced by the write method.

Specified by:

getContentType in interface QueryResponseWriter

Returns:

a Content-Type string, which may not be null.

init

public void init(NamedList args)

Description copied from interface: QueryResponseWriter

init will be called just once, immediately after creation.

The args are user-level initialization parameters that may be specified when declaring a response writer in solrconfig.xml

Specified by:

init in interface NamedListInitializedPlugin

Specified by:

init in interface QueryResponseWriter

getParsedResponse

public static NamedList<Object> getParsedResponse(SolrQueryRequest req,
                                                  SolrQueryResponse rsp)

TODO -- there may be a way to do this without marshal at all...

Returns:

a response object equivalent to what you get from the XML/JSON/javabin parser. Documents become SolrDocuments, DocList becomes SolrDocumentList etc.

Since:

solr 1.4
