# ColorInterpolationSegment

from pandac.PandaModules import ColorInterpolationSegment

Class : ColorInterpolationSegment
Description : A single unit of interpolation. The begin and end times are interpolated over the lifetime of the particle, thus have the range of [0,1]. Each segment also has a function associated with it.

getFunction TypedReferenceCount *ColorInterpolationSegment::get_function(void) const; INLINE ColorInterpolationFunction* get_function() const; Description : Returns a reference to the function object corresponding to this segment.

getId int ColorInterpolationSegment::get_id(void) const; Description : Returns the id assigned to this segment by the manager that created it.

getTimeBegin float ColorInterpolationSegment::get_time_begin(void) const; INLINE ColorInterpolationFunction* get_function() const; Description : Returns the point in the particle's lifetime at which this segment begins its effect. It is an interpolated value in the range [0,1].

getTimeEnd float ColorInterpolationSegment::get_time_end(void) const; Description : Returns the point in the particle's lifetime at which this segment's effect stops. It is an interpolated value in the range [0,1].

isEnabled bool ColorInterpolationSegment::is_enabled(void) const; Description : Returns whether the segments effects are being applied.

isModulated bool ColorInterpolationSegment::is_modulated(void) const; Description : Returns whether the function is additive or modulated.

setEnabled void ColorInterpolationSegment::set_enabled(bool const enabled); Description : Sets whether the segments effects should be applied.

setFunction void ColorInterpolationSegment::set_function(ColorInterpolationFunction *function); Description : Sets the function that the segment will use for its interpolation calculations.

setIsModulated void ColorInterpolationSegment::set_is_modulated(bool const flag); Description : Sets how the function is applied to the final color. If true, the value is multiplied. If false, the value is simply added. Default is true.

setTimeBegin void ColorInterpolationSegment::set_time_begin(float const time); Description : Sets the point in the particle's lifetime at which this segment begins its effect. It is an interpolated value in the range [0,1].

setTimeEnd void ColorInterpolationSegment::set_time_end(float const time); Description : Sets the point in the particle's lifetime at which this segment's effect ends. It is an interpolated value in the range [0,1].

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 void 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.

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.

testRefCountNonzero bool ReferenceCount::test_ref_count_nonzero(void) const; Description: Does some easy checks to make sure that the reference count isn't zero, or completely bogus. Returns true if ok, false otherwise.

unref bool 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 true if the new reference count is nonzero, false if it is zero.
