A handle to a Maya blend shape description.
This is just one target of a Maya BlendShape object, and thus corresponds more or less one-to-one with a single Egg morph target. (We don't attempt to support Maya's chained target shapes here; should we need to later, it would mean breaking each of those target shapes on the one continuous Maya slider into a separate MayaBlendDesc object, and synthesizing the egg slider values appropriately.)

bool ReferenceCount::has_weak_list | ( | ) | const [inline, inherited] |
Returns true if this particular ReferenceCount object has a WeakReferenceList created, false otherwise.
In general, this will be true if there was ever a WeakPointerTo created for this object (even if there is not any for it now).

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.

void MayaBlendDesc::set_slider | ( | float | value | ) |
Moves the Maya slider associated with this blend shape to the indicated value.
This will move all the affected vertices.

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.
