◆ setJvm()

void xmog_JavaVM::setJvm ( xmog_jvm * jvm_ )

Sets the higher-level abstraction that owns this instance.

This operation will only succeed once.

Member Data Documentation

◆ theJvm

xmog_jvm* xmog_JavaVM::theJvm

protected

A pointer to the higher level abstraction instance that owns this instance.

We don't really need the higher level abstraction unless we want to do things in an optimized fashion at the higher level of abstraction. This could include batching up certain requests.
