-----------------------------------------------------------

Most of the APIs have been implemented using C\+\+. But in order to reduce 
memory leak problem, I use std::shared_ptr which is supported in C\+\+11.

Whether C\+\+ sources will only be compiled in compilers which support at C++11 
(with option -std=c\+\+11)?

If so, I will use std::shared_ptr, otherwise I am considering boost::shared_ptr 
from boost (Actually I think shared_ptr comes from tr1 which originates from 
boost)

> The Java reader can push down predicates to filter the data being read. The 
> C++ reader doesn't do that yet.
