java.lang.Object org.codehaus.groovy.classgen.asm.CompileStack
public class CompileStack extends Object
This class is a helper for AsmClassGenerator. It manages different aspects of the code of a code block like handling labels, defining variables, and scopes. After a MethodNode is visited clear should be called, for initialization the method init should be used.
