Detailed Description
This is the base class for a ref-counted object. Derive from DynSharedI and implement ref-counting (support for atomic ref handling in pi/Atomic.h).It adds ref counting methods to the object: doAddRef, doRelease. On object creation, it is assumed that the internal ref counter is set to 1 (NOTE: not 0).
DynSharedI derives from DynObj (more fundamental) since a ref-counted object depends on a mechanism to delete itself (which DynObj provides).
The DynSharedC is a default implementation that implements the ref counting methods.
There are some other helpful classes:
- ToDynShared<T> when converting a DynObj (or really any other object) to a shared object at compile time. do_cast<SomeType*>(p) will work for querying types.
- RTDynShared does the same at run-time, given a DynObj*. do_cast<SomeType*>(p) will work (partially) for querying types.
Member Function Documentation
| virtual DynObjType* docall DynSharedI::doGetType | ( | const DynI ** | pself = 0 |
) | const [virtual] |
Returns type of this object. Each type that wants to make itself known should override this method. DynI knows its own type so we get the type without any lookup. It is faster and works without registration.
- Parameters:
-
pself allows fetching the actual 'this' used inside doGetType (from a side base, this will be different to the 'this' of the caller).
- Returns:
- A DynObjType pointer
Reimplemented from DynObj.
| virtual int docall DynSharedI::doAddRef | ( | ) | [pure virtual] |
Increases the reference count of the object
- Returns:
- the updated ref count value
| virtual int docall DynSharedI::doRelease | ( | ) | [pure virtual] |
Decreares the reference count of the object and destroy if zero.
- Returns:
- the updated ref count value
| virtual int docall DynSharedI::IncRef | ( | ) | [inline, virtual] |
