Reimplemented from EventStoreValueBase. Definition at line 282 of file transformState.h.

int ReferenceCount::get_ref_count (   )  const [inline, inherited]

Returns the current reference count. Definition at line 183 of file referenceCount.I.

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(). Definition at line 71 of file typedObject.I. References TypeHandle::get_name(), TypedObject::get_type(), and INLINE.

const TransformState * EventStoreTransform::get_value (  void   )  const [inline]

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

Reimplemented from EventStoreValueBase. Definition at line 285 of file transformState.h.

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. Definition at line 86 of file typedObject.I. Referenced by EggMaterialCollection::collapse_equivalent_materials(), EggTextureCollection::collapse_equivalent_textures(), DeferredNodeProperty::compose(), AnimBundleMaker::create_s_channel(), CharacterMaker::create_slider(), ProjectionScreen::cull_callback(), DataNode::define_output(), EggNode::determine_draw_order(), CharacterMaker::egg_to_index(), EggGroupUniquifier::EggGroupUniquifier(), EggPoolUniquifier::EggPoolUniquifier(), EggGroupNode::find_textures(), StaticTextFont::get_glyph(), EggMaterialCollection::insert_materials(), EggTextureCollection::insert_textures(), CharacterJoint::make_copy(), PT(), EggGroupNode::r_flatten_transforms(), EggGroupNode::r_transform_vertices(), EggGroupNode::recompute_polygon_normals(), CollisionLevelState::reserve(), PandaFramework::reset_frame_rate(), PandaFramework::set_texture(), EggGroupNode::steal_children(), and DataGraphTraverser::traverse().

void EventStoreTransform::output (  ostream &  out  )  const [virtual]

Implements EventStoreValueBase. Definition at line 1504 of file transformState.cxx.

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. Definition at line 225 of file referenceCount.I. Referenced by ClientDevice::ClientDevice(), EggGroupNode::find_textures(), EggGroupNode::r_apply_texmats(), EggGroupNode::r_flatten_transforms(), and EggGroupNode::reverse_vertex_ordering().

void EventStoreTransform::set_value (  const TransformState *  value  )  [inline]

Definition at line 713 of file transformState.I.

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.
