+--com.smardec.j2native.PointerArgument
- All Implemented Interfaces:
- java.lang.Cloneable, PointerType
- Direct Known Subclasses:
- Pointer.Void, TypedPointer
- public abstract class PointerArgument
- extends Argument
- implements PointerType
PointerArgument is an abstract class with a partly realized
PointerType interface. This class is a base class for all
pointer types.
