## Public Member Functions
unsigned int | getHash ()
bool | isNull ()
| Returns true if the PointerTo is a NULL pointer, false otherwise.

## Detailed Description

This is the non-template part of the base class for PointerTo and ConstPointerTo.

It is necessary so we can keep a pointer to a non-template class within the ReferenceCount object, to implement weak reference pointers--we need to have something to clean up when the ReferenceCount object destructs.

This is the base class for PointerToBase<T>.

## Member Function Documentation

unsigned int getHash | ( |  | ) |

bool isNull | ( |  | ) |

Returns true if the PointerTo is a NULL pointer, false otherwise.

(Direct comparison to a NULL pointer also works.)

Reimplemented in PointerToConnection.
