Looking at cpp/PythonSearch.cpp, it maps different java overloadings to
different method names:
jfloat PythonSimilarity::idf(jint docFreq, jint numDocs) -> "idf" method
jfloat PythonSimilarity::idf(::java::util::Collection *terms,
::org::apache::lucene::search::Searcher
*searcher) -> "idfTerms" method
jfloat PythonSimilarity::idf(::org::apache::lucene::index::Term *term,
::org::apache::lucene::search::Searcher
*searcher) -> "idfTerm" method
I've overridden the idfTerm method, and it works for me.
Andi just checked in the SimilarityDelegator method, which sounds
like what you want: see

Hope this helps.
