Classpublic final class Placement
InheritancePlacement Inheritance Object

Class which wraps information related to timeline placement. A placement on the timeline can be indicated through an actual time position or through some predefined virtual positions: - PRE_ROLL at the beginning of the timeline - MID_ROLL in the middle of the timeline - POST_ROLL at the end of the timeline The actual time position is mandatory for MID-ROLLS positions. A placement can also indicate that the placement will affect a contiguous interval on the timeline starting for the indicated position. Duration property will indicate the length of the interval.
