void ReferenceCount::local_object | ( | ) | [inline, inherited] |
This function should be called, once, immediately after creating a new instance of some ReferenceCount-derived object on the stack.
This allows the object to be passed to functions that will increment and decrement the object's reference count temporarily, and it will prevent the object from being deleted (inappropriately), when the reference count returns to zero. It actually achieves this by setting a large positive value in the reference count field.

void Namable::output | ( | ostream & | out | ) | const [inline, inherited] |
Outputs the Namable.
This function simply writes the name to the output stream; most Namable derivatives will probably redefine this.

void ReferenceCount::ref | ( | ) | const [inline, inherited] |
Explicitly increments the reference count.
User code should avoid using ref() and unref() directly, which can result in missed reference counts. Instead, let a PointerTo object manage the reference counting automatically.
This function is const, even though it changes the object, because generally fiddling with an object's reference count isn't considered part of fiddling with the object. An object might be const in other ways, but we still need to accurately count the number of references to it.

bool ReferenceCount::unref | ( | ) | const [inline, virtual, inherited] |
Explicitly decrements the reference count.
Note that the object will not be implicitly deleted by unref() simply because the reference count drops to zero. (Having a member function delete itself is problematic.) However, see the helper function unref_delete().
User code should avoid using ref() and unref() directly, which can result in missed reference counts. Instead, let a PointerTo object manage the reference counting automatically.
This function is const, even though it changes the object, because generally fiddling with an object's reference count isn't considered part of fiddling with the object. An object might be const in other ways, but we still need to accurately count the number of references to it.
The return value is true if the new reference count is nonzero, false if it is zero.
