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.

Definition at line 276 of file referenceCount.I.

Referenced by PGTop::cull_callback(), BoundingSphere::extend_by_hexahedron(), AsyncTaskManager::find_task(), AsyncTaskManager::find_tasks(), and AsyncTaskManager::find_tasks_matching().

void EggNamedObject::output ( ostream &  out) const [inherited]

Outputs the Namable.

This function simply writes the name to the output stream; most Namable derivatives will probably redefine this.

Reimplemented from Namable.

Definition at line 28 of file eggNamedObject.cxx.

References Namable::has_name().

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.

Definition at line 179 of file referenceCount.I.

References ReferenceCount::test_ref_count_integrity().

Referenced by CachedTypedWritableReferenceCount::cache_ref(), TypedWritable::decode_raw_from_bam_stream(), NodeCachedReferenceCount::node_ref(), NodeReferenceCount::node_ref(), BamCacheRecord::set_data(), CullableObject::set_draw_callback(), and ModelRoot::set_reference().

void EggObject::set_user_data ( EggUserData user_data) [inherited]

Sets the user data associated with this object.

This may be any EggUserData-derived object. The egg library will do nothing with this pointer, except to hold its reference count and return the pointer on request.

The EggObject maintains multiple different EggUserData pointers, one for each unique type (as reported by get_type()). If you know that only one type of EggUserData object will be added in your application, you may use the query functions that accept no parameters, but it is recommended that in general you pass in the type of your particular user data, to allow multiple applications to coexist in the same egg data.

This pointer is also copied by the copy assignment operator and copy constructor.

Definition at line 89 of file eggObject.cxx.

Referenced by MayaNodeTree::get_egg_group(), and EggBinner::prepare_node().

void EggVertexUV::set_uv ( const TexCoordd uv) [inline]

Sets the texture coordinate pair.

This makes the texture coordinate a 2-d texture coordinate, which is the usual case.

Definition at line 100 of file eggVertexUV.I.

void EggVertexUV::set_uvw ( const TexCoord3d uvw) [inline]

Sets the texture coordinate triple.

This makes the texture coordinate a 3-d texture coordinate.

Definition at line 112 of file eggVertexUV.I.

bool ReferenceCount::test_ref_count_integrity ( ) const [inline, inherited]
bool ReferenceCount::test_ref_count_nonzero ( ) const [inline, inherited]

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

Returns true if ok, false otherwise.

Definition at line 252 of file referenceCount.I.

References ReferenceCount::do_test_ref_count_nonzero().

Referenced by CopyOnWritePointer::test_ref_count_nonzero().

void EggVertexUV::transform ( const LMatrix4d mat)

Applies the indicated transformation matrix to the UV's tangent and/or binormal.

This does nothing if there is no tangent or binormal.

Definition at line 104 of file eggVertexUV.cxx.

References LVecBase3d::normalize().

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.

void ReferenceCount::weak_unref ( WeakPointerToVoid ptv) [inline, inherited]

It must have previously been added via a call to weak_ref().

Writes the first line of the egg object, e.g.

"<Group> group_name {" or some such. It automatically enquotes the name if it contains any special characters. egg_keyword is the keyword that begins the line, e.g. "<Group>".
