Class RTTI0DataType

  • All Implemented Interfaces:
    BuiltInDataType, DataType, Dynamic, ExtensionPoint, java.util.EventListener, javax.swing.event.ChangeListener
    public class RTTI0DataType
extends RTTIDataType
    The RTTI0 data type represents a TypeDescriptor structure.

    Fields for this RunTimeTypeInformation structure can be found on http://www.openrce.org 

     struct TypeDescriptor {
     Pointer vfTablePointer;
     Pointer dataPointer;
     NullTerminatedString name; // mangled version of class name
 }

    RTTI_Type_Descriptor is the label for the RTTI0 data structure.
