BaseMediaChunkIterator

Kotlin |Java

@UnstableApi
public abstract class BaseMediaChunkIterator implements MediaChunkIterator

Known direct subclasses

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

Base class for MediaChunkIterators. Handles next and isEnded, and provides a bounds check for child classes.

Summary

Protected fields
`long`	`currentIndex`

Public constructors
`BaseMediaChunkIterator(long fromIndex, long toIndex)` Creates base iterator.

Public methods
`boolean`	`isEnded()` Returns whether the iteration has reached the end of the available data.
`boolean`	`next()` Moves the iterator to the next media chunk.
`void`	`reset()` Resets the iterator to the initial position.

Protected methods
`final void`	`checkInBounds()` Verifies that the iterator points to a valid element.
`final long`	`getCurrentIndex()` Returns the current index this iterator is pointing to.

static final MediaChunkIterator

EMPTY

An empty media chunk iterator without available data.

`abstract long`	`getChunkEndTimeUs()` Returns the media end time of the chunk, in microseconds.
`abstract long`	`getChunkStartTimeUs()` Returns the media start time of the chunk, in microseconds.
`abstract DataSpec`	`getDataSpec()` Returns the `DataSpec` used to load the media chunk.

protected long currentIndex

public BaseMediaChunkIterator(long fromIndex, long toIndex)

Creates base iterator.

Parameters
`long fromIndex`	The first available index.
`long toIndex`	The last available index.

public boolean isEnded()

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

public boolean next()

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.

public void reset()

Resets the iterator to the initial position.

protected final void checkInBounds()

Verifies that the iterator points to a valid element.

Throws
`java.util.NoSuchElementException`	If the iterator does not point to a valid element.

protected final long getCurrentIndex()

Returns the current index this iterator is pointing to.
