org.eclipse.m2m.atl.engine.vm.ASMExecEnv

public class ASMExecEnv
extends ExecEnv

An ASMExecEnv is an execution environment for ATL Stack Machine programs. It holds: * the only call Stack of the machine (no multi-thread support required), * the Map of models used by the program, * the Map of program-specific operations and attribute helpers. This permits several transformations to be launched in sequence without altering one another.
