Constructor Detail

SolrCore.LazyQueryResponseWriterWrapper

public SolrCore.LazyQueryResponseWriterWrapper(SolrCore core,
                                       String className,
                                       NamedList args)

Method Detail

getWrappedWriter

public QueryResponseWriter getWrappedWriter()

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 QueryResponseWriter

Specified by:

init in interface NamedListInitializedPlugin

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: 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.

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.
