C++ (Cpp) ByteBuffer::Reserve示例

 typename std::enable_if<!HasFunc_WriteTo<T>::value, void>::type WriteSwitch( ByteBuffer& b, T const& v )
 {
     static_assert( std::is_pod<T>::value, "forget impl WriteTo func ?" );
     b.Reserve( b.dataLen + sizeof( T ) );
     ByteBuffer::WriteCore( b.buf + b.dataLen, v );
     b.dataLen += sizeof( T );
 };
