Class TypeIdMap

java.lang.Object

com.videobug.agent.logging.util.TypeIdMap

public class TypeIdMap
extends Object

This class is to assign an ID for each data type. We use an ID instead of a type name (String) because Java VM may load multiple versions of the same class. In other words, a number of classes may have the same type name.
