Timeline.Window

Kotlin |Java

class Timeline.Window : Bundleable

Holds information about a window in a Timeline. A window usually corresponds to one playlist item and defines a region of media currently available for playback along with additional information such as whether seeking is supported within the window. The figure below shows some of the information defined by a window, as well as how this information relates to corresponding Periods in the timeline.

Constants

CREATOR

@UnstableApi
const val CREATOR: Bundleable.Creator<Timeline.Window!>!

Object that can restore Period from a Bundle.

The uid of a restored instance will be a fake Object and the manifest of the instance will be null.

SINGLE_WINDOW_UID

const val SINGLE_WINDOW_UID: Any!

A uid for a window that must be used for single-window Timelines.

Public constructors

Window

Window()

Creates window.

Public functions

equals

fun equals(obj: Any?): Boolean

fromBundle

@UnstableApi
java-static fun fromBundle(bundle: Bundle!): Timeline.Window!

Restores a Window from a Bundle.

getCurrentUnixTimeMs

fun getCurrentUnixTimeMs(): Long

Returns the current time in milliseconds since the Unix epoch.

This method applies known corrections made available by the media such that this time corresponds to the clock of the media origin server.

getDefaultPositionMs

fun getDefaultPositionMs(): Long

Returns the default position relative to the start of the window at which to begin playback, in milliseconds. May be TIME_UNSET if and only if the window was populated with a non-zero default position projection, and if the specified projection cannot be performed whilst remaining within the bounds of the window.

getDefaultPositionUs

fun getDefaultPositionUs(): Long

Returns the default position relative to the start of the window at which to begin playback, in microseconds. May be TIME_UNSET if and only if the window was populated with a non-zero default position projection, and if the specified projection cannot be performed whilst remaining within the bounds of the window.

getDurationMs

fun getDurationMs(): Long

Returns the duration of the window in milliseconds, or TIME_UNSET if unknown.

getDurationUs

fun getDurationUs(): Long

Returns the duration of this window in microseconds, or TIME_UNSET if unknown.

Sets the data held by this window.

toBundle

Returns a representing the information stored in this object.

It omits the uid and manifest fields. The uid of an instance restored by CREATOR will be a fake Object and the manifest of the instance will be null.

Public properties

Whether it's possible to seek within this window.

lastPeriodIndex

val lastPeriodIndex: Int

val tag: Any?

uid

val uid: Any!

A unique identifier for the window. Single-window Timelines must use SINGLE_WINDOW_UID.
