Detailed Description

Time segment class.

Time segment class implements the visibility control for Demopaja layers and effects. The time segment has a origo in time and set of keys. The origo is treated as the beginning of the effect (or for example begin of animation the effect plays). Every two keys defines a segment where the is_visible() method returns true (the layer/effect is visible). If there is odd number of keys the last key is ignored.

The time values of the keys in a time segment are stored relative to the time origo. The methods, which operates the keys based in time uses the same time space as the time segment itself.

The changes made to the time segment is saved to a undo object if present.

This class is implemented by the system.

Member Function Documentation

virtual KeyC* add_key_at_time (  PajaTypes::int32    i32Time )  [virtual]

Adds a key at specified time. The time is in the same time space as the origo, even keys are relative to the origo of the time segment.

virtual void copy (  Edit::EditableI *    pEditable )  [virtual]

Deep copy from a data block, see Edit::DataBlockI::copy(). Implements EditableI.

virtual Edit::DataBlockI* create (  Edit::EditableI *    pOriginal )  [virtual]

Creates new time segment (used internally), see Edit::EditableI::create(). Implements EditableI.

virtual Edit::DataBlockI* create (    )  [virtual]

Create new time segment. Sets the origo of the time segment to zero. Noe keys are created. Implements EditableI.

TimeSegmentC* create_new (  PajaTypes::int32    i32SegmentStart, PajaTypes::int32    i32SegmentEnd )  [static]

Create new time segment. Sets the origo of the timesegment to i32SegmentStart and creates two keys, first at the point in time of i32SegmentStart and second at the point in time of i32SegmentEnd.

TimeSegmentC* create_new (    )  [static]

Create new time segment. Sets the origo of the time segment to zero. Noe keys are created.

virtual void del_key (  PajaTypes::int32    i32Index )  [virtual]

Deletes a key at specified index.

virtual KeyC* get_key (  PajaTypes::int32    i32Index )  [virtual]

Returns a key at specified index.

virtual KeyC* get_key_at_time (  PajaTypes::int32    i32Time )  [virtual]
