Shawn:
thanks, we found an intermediate solution by serializing our data structure
using string representation, perhaps less optimal than using binary format
directly.
In the original router with JavaBinCodec we found, that
BinaryResponseWriter should also be extended. But the following method is
static and does allow extending:
public static NamedList<Object> getParsedResponse(SolrQueryRequest
req, SolrQueryResponse rsp) {
try {
Resolver resolver = new Resolver(req, rsp.getReturnFields());
ByteArrayOutputStream out = new ByteArrayOutputStream();
new JavaBinCodec(resolver).marshal(rsp.getValues(), out);
InputStream in = new ByteArrayInputStream(out.toByteArray());
return (NamedList<Object>) new JavaBinCodec(resolver).unmarshal(in);
}
catch (Exception ex) {
throw new RuntimeException(ex);
}
}
Shalin:
We needed new data structure in highlighter with more nested levels,
than just one. Something like this (in xml representation):
<lst name="highlighting">
<lst name="doc1">
<arr name="snippets">
<snippet>
<id>id1</id>
<contents>Snippet text goes here</contents>
<other params/>
</snippet>
</arr>
</lst></lst>
Can this be modelled with existing types?
