Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method and Description
`boolean`	`continueLoading(long positionUs)` Attempts to continue loading.
`long`	`getBufferedPositionUs()` Returns an estimate of the position up to which data is buffered.
`long`	`getNextLoadPositionUs()` Returns the next load time, or `C.TIME_END_OF_SOURCE` if loading has finished.
`void`	`reevaluateBuffer(long positionUs)` Re-evaluates the buffer given the playback position.

- Method Detail
  - getBufferedPositionUs
```
long getBufferedPositionUs()
```
    Returns an estimate of the position up to which data is buffered.
    
    Returns:
    
    An estimate of the absolute position in microseconds up to which data is buffered, or C.TIME_END_OF_SOURCE if the data is fully buffered.
  - getNextLoadPositionUs
```
long getNextLoadPositionUs()
```
    Returns the next load time, or C.TIME_END_OF_SOURCE if loading has finished.
  - continueLoading
```
boolean continueLoading(long positionUs)
```
    Attempts to continue loading.
    
    Parameters:
    
    positionUs - The current playback position in microseconds. If playback of the period to which this loader belongs has not yet started, the value will be the starting position in the period minus the duration of any media in previous periods still to be played.
    
    Returns:
    
    True if progress was made, meaning that getNextLoadPositionUs() will return a different value than prior to the call. False otherwise.
  - reevaluateBuffer
```
void reevaluateBuffer(long positionUs)
```
    Re-evaluates the buffer given the playback position.
    Re-evaluation may discard buffered media so that it can be re-buffered in a different quality.
    
    Parameters:
    
    positionUs - The current playback position in microseconds. If playback of this period has not yet started, the value will be the starting position in this period minus the duration of any media in previous periods still to be played.
