References TypedReferenceCount::get_class_type(), and TypedReferenceCount::init_type().

int TypedObject::get_type_index ( ) const [inline, inherited]

Returns the internal index number associated with this object's TypeHandle, a unique number for each different type.
This is equivalent to get_type().get_index().

void Lerp::init_type ( void ) [inline, static]

Reimplemented from TypedReferenceCount.

bool Lerp::is_done ( void ) const

Definition at line 104 of file lerp.cxx.
References _func.

bool TypedObject::is_exact_type ( TypeHandle handle ) const [inline, inherited]

Returns true if the current object is the indicated type exactly.

Definition at line 101 of file typedObject.I.
Referenced by PT(), and CollisionNode::xform().

bool TypedObject::is_of_type ( TypeHandle handle ) const [inline, inherited]

Returns true if the current object is or derives from the indicated type.

Lerp & Lerp::operator= ( const Lerp & )

Definition at line 60 of file lerp.cxx.
References _delta, _endt, _event, _startt, and _t.

int 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.
The return value is the new reference count.

void Lerp::step ( void )

Definition at line 71 of file lerp.cxx.
References _event, and throw_event().

void ReferenceCount::test_ref_count_integrity ( ) const [inline, inherited]

Does some easy checks to make sure that the reference count isn't completely bogus.

Definition at line 328 of file referenceCount.I.
References INLINE.
Referenced by EggNode::determine_bin(), and ReferenceCount::~ReferenceCount().

int ReferenceCount::unref ( ) const [inline, 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; plus, we don't have a virtual destructor anyway.) 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 the new reference count.
