getClassType
static TypeHandle AntialiasAttrib::get_class_type(void);

Undocumented function.

getMode
unsigned short int AntialiasAttrib::get_mode(void) const;

Description: Returns the specified antialias mode.

getModeQuality
unsigned short int AntialiasAttrib::get_mode_quality(void) const;

Description: Returns the specified antialias mode, with the type bits masked out. This therefore indicates only the requested quality settings: one of M_faster, M_better, M_dont_care, or zero (unspecified).

getModeType
unsigned short int AntialiasAttrib::get_mode_type(void) const;

Description: Returns the specified antialias mode, with the quality bits masked out. This therefore indicates only the requested type of antialiasing: M_none, M_auto, or some specific combination.

make
static ConstPointerTo< RenderAttrib > AntialiasAttrib::make(unsigned short int mode);

Description: Constructs a new AntialiasAttrib object.
The mode should be either M_none, M_auto, or a union of any or all of M_point, M_line, M_polygon, and M_multisample. Also, in addition to the above choices, it may include either of M_better of M_faster to specify a performance/quality tradeoff hint.
If M_none is specified, no antialiasing is performed.
If M_multisample is specified, it means to use the special framebuffer multisample bits for antialiasing, if it is available. If so, the M_point, M_line, and M_polygon modes are ignored. This advanced antialiasing mode is only available on certain graphics hardware. If it is not available, the M_multisample bit is ignored (and the other modes may be used instead, if specified).
M_point, M_line, and/or M_polygon specify per-primitive smoothing. When enabled, M_point and M_line may force transparency on. M_polygon requires a frame buffer that includes an alpha channel, and it works best if the primitives are sorted front-to-back.
If M_auto is specified, M_multisample is selected if it is available, otherwise M_polygon is selected, unless drawing lines or points, in which case M_line or M_point is selected (these two generally produce better results than M_multisample)

compareTo
int RenderAttrib::compare_to(RenderAttrib const &other) const;

Description: Provides an arbitrary ordering among all unique RenderAttribs, so we can store the essentially different ones in a big set and throw away the rest.
This method is not needed outside of the RenderAttrib class because all equivalent RenderAttrib objects are guaranteed to share the same pointer; thus, a pointer comparison is always sufficient.

getClassType
static TypeHandle RenderAttrib::get_class_type(void);

Undocumented function.

getNumAttribs
static int RenderAttrib::get_num_attribs(void);

Description: Returns the total number of unique RenderAttrib objects allocated in the world. This will go up and down during normal operations.

listAttribs
static void RenderAttrib::list_attribs(ostream &out);

Description: Lists all of the RenderAttribs in the cache to the output stream, one per line. This can be quite a lot of output if the cache is large, so be prepared.

output
virtual void RenderAttrib::output(ostream &out) const;

Description:

validateAttribs
static bool RenderAttrib::validate_attribs(void);

Description: Ensures that the cache is still stored in sorted order. Returns true if so, false if there is a problem (which implies someone has modified one of the supposedly-const RenderAttrib objects).

write
virtual void RenderAttrib::write(ostream &out, int indent_level) const;

Description:

getClassType
static TypeHandle TypedWritableReferenceCount::get_class_type(void);

Undocumented function.

getClassType
static TypeHandle TypedWritable::get_class_type(void);

Undocumented function.

getBestParentFromSet
int TypedObject::get_best_parent_from_Set(set< int > const &) const;

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

getClassType
static TypeHandle TypedObject::get_class_type(void);

Undocumented function.

getType
virtual TypeHandle TypedObject::get_type(void) const = 0;

Derived classes should override this function to return get_class_type().

getTypeIndex
int TypedObject::get_type_index(void) const;

Description: 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().

isExactType
bool TypedObject::is_exact_type(TypeHandle handle) const;

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

isOfType
bool TypedObject::is_of_type(TypeHandle handle) const;

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

getClassType
static TypeHandle ReferenceCount::get_class_type(void);

Undocumented function.

getRefCount
int ReferenceCount::get_ref_count(void) const;

Description: Returns the current reference count.

ref
int ReferenceCount::ref(void) const;

Description: 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.

testRefCountIntegrity
bool ReferenceCount::test_ref_count_integrity(void) const;

Description: Does some easy checks to make sure that the reference count isn't completely bogus. Returns true if ok, false otherwise.

unref
int ReferenceCount::unref(void) const;

Description: 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().
