Detailed Description

Structure that defines how to combine and sort sections in the same track row after processing on a per-row basis.

Constructor & Destructor Documentation

FMovieSceneTrackSegmentBlender()

FMovieSceneTrackSegmentBlender::FMovieSceneTrackSegmentBlender ( )

inline

Default constructor

~FMovieSceneTrackSegmentBlender()

virtual FMovieSceneTrackSegmentBlender::~FMovieSceneTrackSegmentBlender ( )

inlinevirtual

Member Function Documentation

AllowEmptySegments()

bool FMovieSceneTrackSegmentBlender::AllowEmptySegments ( ) const

inline

Check whether the resulting segments be empty. When true, Empty segments will be allowed to be added to the resulting evaluation field.

Note

: use when evaluation of a track should always be performed, even if there are no sections at the current time

Blend()

virtual void FMovieSceneTrackSegmentBlender::Blend ( FSegmentBlendData &  BlendData ) const

inlinevirtual

Blend the specified data by performing some specific processing such as sorting or filtering

Parameters

BlendData

Blend data to be modified to suit the implementation's will

Reimplemented in FMovieSceneAdditiveCameraTrackBlender.

CanFillEmptySpace()

bool FMovieSceneTrackSegmentBlender::CanFillEmptySpace ( ) const

inline

Check whether these rules can fill empty space between segments (such as to evaluate the nearest section)

Note

: use in combination with AllowEmptySegments when evaluation of a track should always be performed, even if there are no sections at the current time

InsertEmptySpace()

virtual TOptional< FMovieSceneSegment > FMovieSceneTrackSegmentBlender::InsertEmptySpace ( const TRange< FFrameNumber > &  Range, const FMovieSceneSegment *  PreviousSegment, const FMovieSceneSegment *  NextSegment  ) const

inlinevirtual

Implementation function to insert empty space between two other segments or at the start/end

Parameters

Range	The time range for the potential new segment
PreviousSegment	A pointer to the previous segment if there is one. Null if the empty space is before the first segment.
Next	A pointer to the subsequent segment if there is one. Null if the empty space is after the last segment.

Returns

An optional new segment to define

Reimplemented in FEvaluateNearestSegmentBlender.

Member Data Documentation

bAllowEmptySegments

bool FMovieSceneTrackSegmentBlender::bAllowEmptySegments

protected

Whether we allow empty segments to be evaluated or not

bCanFillEmptySpace

bool FMovieSceneTrackSegmentBlender::bCanFillEmptySpace

protected

Whether we can fill empty space (false signifies InsertEmptySpace will never be called)
