Method Details

getContentType

public String getContentType(SolrQueryRequest req,
 SolrQueryResponse res)

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.

write

public void write(Writer writer,
 SolrQueryRequest req,
 SolrQueryResponse res)
           throws IOException

Description copied from interface: TextQueryResponseWriter

Write a SolrQueryResponse in a textual manner.

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 TextQueryResponseWriter

Throws:

IOException
