Detailed Description

template<typename C>
struct MemberIdPreloadedStrongCache< C >

Provides caching of JNI Field/Method IDs using strong class references with preloading (at class initialization) – VERY TRICKY, NOT SUPPORTED.

Member Function Documentation

template<typename C >

static jclass MemberIdPreloadedStrongCache< C >::getClass ( JNIEnv *  env )

inlinestatic

Returns a JNI Reference to the class declaring the member specified by info type 'C'.

Depending upon the underlying caching strategy, a returned reference may be local or global, weak or strong; the scope of its use must be demarcated by releaseRef().

Pre condition:

• this thread has no pending JNI exception (!env->ExceptionCheck())

Post condition:

• return value is NULL:
  • this thread has a pending JNI exception (env->ExceptionCheck()) otherwise:
  • this thread has no pending JNI exception (!env->ExceptionCheck())
  • the returned reference is valid (at least) until releaseRef()

Reimplemented from MemberIdStrongCache< C >.
