getClassType static TypeHandle ColorScaleAttrib::get_class_type(void); Undocumented function. |
getScale LVecBase4f const &ColorScaleAttrib::get_scale(void) const; Description: Returns the scale to be applied to colors. |
hasScale bool ColorScaleAttrib::has_scale(void) const; Description: Returns true if the ColorScaleAttrib has a non-identity scale, false otherwise (in which case it might be an off attrib or an identity attrib). |
isIdentity bool ColorScaleAttrib::is_identity(void) const; Description: Returns true if the ColorScaleAttrib is an identity attrib, false if it is either an off attrib or it has a scale. |
isOff bool ColorScaleAttrib::is_off(void) const; Description: Returns true if the ColorScaleAttrib will ignore any color scales inherited from above, false otherwise. This is not the same thing as !has_scale(); a ColorScaleAttrib may have the "off" flag set and also have another scale specified. |
make static ConstPointerTo< RenderAttrib > ColorScaleAttrib::make(LVecBase4f const &scale); Description: Constructs a new ColorScaleAttrib object that indicates geometry should be scaled by the indicated factor. |
makeIdentity static ConstPointerTo< RenderAttrib > ColorScaleAttrib::make_identity(void); Description: Constructs an identity scale attrib. |
makeOff static ConstPointerTo< RenderAttrib > ColorScaleAttrib::make_off(void); Description: Constructs a new ColorScaleAttrib object that ignores any ColorScaleAttrib inherited from above. You may also specify an additional color scale to apply to geometry below (using set_scale()). |
setScale ConstPointerTo< RenderAttrib > ColorScaleAttrib::set_scale(LVecBase4f const &scale) const; Description: Returns a new ColorScaleAttrib, just like this one, but with the scale changed to the indicated value. |
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(). 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. |
