Detailed Description

Couple (object_id, pointer_to_object).

This class consists of two items: unique ID of the object in profiler library's memory (having information about corresponding Java object) and pointer to this object. ID is used during the communication between Java and C++ part of Java profiler, ID uniquely identifies the object - pointers to objects cannot be transfered between Java and C++ - profiled JVM can be run on various platforms with various pointer length and/or on different machine than IDE, too. So, that's why "jint" IDs are used and later transformed to pointers by the profiler library.
