interface MediaChunkIterator

Known direct subclasses

BaseMediaChunkIterator

BaseMediaChunkIterator

Base class for MediaChunkIterators.

Known indirect subclasses

DefaultDashChunkSource.RepresentationSegmentIterator, FakeAdaptiveDataSet.Iterator, FakeMediaChunkIterator

`DefaultDashChunkSource.RepresentationSegmentIterator`	`MediaChunkIterator` wrapping a `RepresentationHolder`.
`FakeAdaptiveDataSet.Iterator`	`MediaChunkIterator` for the chunks defined by a fake adaptive data set.
`FakeMediaChunkIterator`	Fake `MediaChunkIterator`.

Iterator for media chunk sequences.

The iterator initially points in front of the first available element. The first call to next moves the iterator to the first element. Check the return value of next or isEnded to determine whether the iterator reached the end of the available data.

Summary

Constants
`const MediaChunkIterator!`	`EMPTY` An empty media chunk iterator without available data.

Public functions
`Long`	`getChunkEndTimeUs()` Returns the media end time of the chunk, in microseconds.
`Long`	`getChunkStartTimeUs()` Returns the media start time of the chunk, in microseconds.
`DataSpec!`	`getDataSpec()` Returns the `DataSpec` used to load the media chunk.
`Boolean`	`isEnded()` Returns whether the iteration has reached the end of the available data.
`Boolean`	`next()` Moves the iterator to the next media chunk.
`Unit`	`reset()` Resets the iterator to the initial position.

Constants

EMPTY

const val EMPTY: MediaChunkIterator!

An empty media chunk iterator without available data.

Public functions

getChunkEndTimeUs

fun getChunkEndTimeUs(): Long

Returns the media end time of the chunk, in microseconds.

Throws
`java.util.NoSuchElementException`	If the method is called before the first call to `next` or when `isEnded` is true.

getChunkStartTimeUs

fun getChunkStartTimeUs(): Long

Returns the media start time of the chunk, in microseconds.

Throws
`java.util.NoSuchElementException`	If the method is called before the first call to `next` or when `isEnded` is true.

getDataSpec

fun getDataSpec(): DataSpec!

Returns the DataSpec used to load the media chunk.

Throws
`java.util.NoSuchElementException`	If the method is called before the first call to `next` or when `isEnded` is true.

isEnded

fun isEnded(): Boolean

Returns whether the iteration has reached the end of the available data.

fun next(): Boolean

Moves the iterator to the next media chunk.

Check the return value or isEnded to determine whether the iterator reached the end of the available data.

Returns
`Boolean`	Whether the iterator points to a media chunk with available data.

reset

fun reset(): Unit

Resets the iterator to the initial position.
