Detailed Description

template<typename T>
class connectivity::jdbc::LocalRef< T >

helper class to hold a local ref to a JNI object

Note that this class never actually calls NewLocalRef. It is assumed that all objects passed are already acquired with a local ref (as it usually is the case if you obtain the object from a JNI method).
