Member Function Documentation

template<typename C >

static ID_t MemberIdCache< C >::getId ( JNIEnv *  env, jclass  cls  )

inlinestatic

Returns the JNI Field/Method ID of a Java class member.

The member ID is only valid along with a class object obtained by getClass() and before releaseRef().

Pre condition:

• this thread has no pending JNI exception (!env->ExceptionCheck())
• a valid class reference obtained by getClass(): assert(cls != NULL)

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 member ID is valid (at least) until releaseRef()

Reimplemented from MemberId< C >.
