| QueryResponseWriter | | public interface QueryResponseWriter (Code) | | Implementations of QueryResponseWriter are used to format responses to query requests.
Different QueryResponseWriters are registered with the SolrCore.
One way to register a QueryResponseWriter with the core is thorugh the solrconfig.xml file.
Example solrconfig.xml entry to register a QueryResponseWRiter implementation to
handle all queries with a writer type of "simple":
<queryResponseWriter name="simple" class="foo.SimpleResponseWriter" />
A single instance of any registered QueryResponseWriter is created
via the default constructor and is reused for all relevant queries.

| getContentType | | public String getContentType(SolrQueryRequest request, SolrQueryResponse response)(Code) | | 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
corrispond with the output produced by the write method.
a Content-Type string, which may not be null. |
| init | | public void init(NamedList args)(Code) | | 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
|
| write | | public void write(Writer writer, SolrQueryRequest request, SolrQueryResponse response) throws IOException(Code) | | Write a SolrQueryResponse, this method must be thread save.
Information about the request (in particular: formating 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.
