Inherited functions

From androidx.media3.common.Timeline

`Timeline!`	`@UnstableApi copyWithSingleWindow(windowIndex: Int)` Returns a copy of this timeline containing just the single specified `Window`.
`Boolean`	`equals(obj: Any?)`
`java-static Timeline!`	`@UnstableApi fromBundle(bundle: Bundle!)` Restores a `Timeline` from a `Bundle`.
`Int`	`getFirstWindowIndex(shuffleModeEnabled: Boolean)` Returns the index of the first window in the playback order depending on whether shuffling is enabled.
`Int`	`getLastWindowIndex(shuffleModeEnabled: Boolean)` Returns the index of the last window in the playback order depending on whether shuffling is enabled.
`Int`	`getNextPeriodIndex( periodIndex: Int, period: Timeline.Period!, window: Timeline.Window!, @Player.RepeatMode repeatMode: Int, shuffleModeEnabled: Boolean )` Returns the index of the period after the period at index `periodIndex` depending on the `repeatMode` and whether shuffling is enabled.
`Int`	`getNextWindowIndex( windowIndex: Int, @Player.RepeatMode repeatMode: Int, shuffleModeEnabled: Boolean )` Returns the index of the window after the window at index `windowIndex` depending on the `repeatMode` and whether shuffling is enabled.
`Timeline.Period!`	`getPeriod(periodIndex: Int, period: Timeline.Period!)` Populates a `Period` with data for the period at the specified index.
`Timeline.Period!`	`getPeriodByUid(periodUid: Any!, period: Timeline.Period!)` Populates a `Period` with data for the period with the specified unique identifier.
`Pair<Any!, Long!>!`	`@UnstableApi @InlineMe(replacement = "this.getPeriodPositionUs(window, period, windowIndex, windowPositionUs)") getPeriodPosition( window: Timeline.Window!, period: Timeline.Period!, windowIndex: Int, windowPositionUs: Long )` This function is deprecated. Use `getPeriodPositionUs` instead.
`Pair<Any!, Long!>?`	`@UnstableApi @InlineMe(replacement = "this.getPeriodPositionUs(" + "window, period, windowIndex, windowPositionUs, defaultPositionProjectionUs)") getPeriodPosition( window: Timeline.Window!, period: Timeline.Period!, windowIndex: Int, windowPositionUs: Long, defaultPositionProjectionUs: Long )` This function is deprecated. Use `getPeriodPositionUs` instead.
`Pair<Any!, Long!>!`	`getPeriodPositionUs( window: Timeline.Window!, period: Timeline.Period!, windowIndex: Int, windowPositionUs: Long )` Calls `getPeriodPositionUs` with a zero default position projection.
`Pair<Any!, Long!>?`	`getPeriodPositionUs( window: Timeline.Window!, period: Timeline.Period!, windowIndex: Int, windowPositionUs: Long, defaultPositionProjectionUs: Long )` Converts `(windowIndex, windowPositionUs)` to the corresponding `(periodUid, periodPositionUs)`.
`Int`	`getPreviousWindowIndex( windowIndex: Int, @Player.RepeatMode repeatMode: Int, shuffleModeEnabled: Boolean )` Returns the index of the window before the window at index `windowIndex` depending on the `repeatMode` and whether shuffling is enabled.
`Timeline.Window!`	`getWindow(windowIndex: Int, window: Timeline.Window!)` Populates a `Window` with data for the window at the specified index.
`Int`	`hashCode()`
`Boolean`	`isEmpty()` Returns whether the timeline is empty.
`Boolean`	`isLastPeriod( periodIndex: Int, period: Timeline.Period!, window: Timeline.Window!, @Player.RepeatMode repeatMode: Int, shuffleModeEnabled: Boolean )` Returns whether the given period is the last period of the timeline depending on the `repeatMode` and whether shuffling is enabled.

Public constructors

PlaceholderTimeline

PlaceholderTimeline(mediaItem: MediaItem!)

Creates a new instance with the given media item.

Public functions

getIndexOfPeriod

fun getIndexOfPeriod(uid: Any!): Int

Returns the index of the period identified by its unique uid, or INDEX_UNSET if the period is not in the timeline.

Parameters
`uid: Any!`	A unique identifier for a period.

Returns
`Int`	The index of the period, or `INDEX_UNSET` if the period was not found.

getPeriod

fun getPeriod(periodIndex: Int, period: Timeline.Period!, setIds: Boolean): Timeline.Period!

Populates a Period with data for the period at the specified index.

Parameters
`periodIndex: Int`	The index of the period.
`period: Timeline.Period!`	The `Period` to populate. Must not be null.
`setIds: Boolean`	Whether `id` and `uid` should be populated. If false, the fields will be set to null. The caller should pass false for efficiency reasons unless the fields are required.

Returns
`Timeline.Period!`	The populated `Period`, for convenience.

getPeriodCount

fun getPeriodCount(): Int

Returns the number of periods in the timeline.

getUidOfPeriod

fun getUidOfPeriod(periodIndex: Int): Any!

`periodIndex: Int`	The index of the period.

Returns
`Any!`	The unique id of the period.

getWindow

fun getWindow(
    windowIndex: Int,
    window: Timeline.Window!,
    defaultPositionProjectionUs: Long
): Timeline.Window!

Populates a Window with data for the window at the specified index.

Parameters
`windowIndex: Int`	The index of the window.
`window: Timeline.Window!`	The `Window` to populate. Must not be null.
`defaultPositionProjectionUs: Long`	A duration into the future that the populated window's default start position should be projected.

Returns
`Timeline.Window!`	The populated `Window`, for convenience.

getWindowCount

fun getWindowCount(): Int
