```
public FailOnCloseDataSink(Cache cache,
                           AtomicBoolean failOnClose)
```
    Creates an instance.
    
    Parameters:
    
    cache - The cache to write to when not in fail-on-close mode.
    
    failOnClose - An AtomicBoolean whose value is read in each call to open(com.google.android.exoplayer2.upstream.DataSpec) to determine whether to enable fail-on-close for the read that's being started.

  - open
```
public void open(DataSpec dataSpec)
          throws IOException
```
    Description copied from interface: DataSink
    
    Opens the sink to consume the specified data.
    Note: If an IOException is thrown, callers must still call DataSink.close() to ensure that any partial effects of the invocation are cleaned up.
    
    Specified by:
    
    open in interface DataSink
    
    Parameters:
    
    dataSpec - Defines the data to be consumed.
    
    Throws:
    
    IOException - If an error occurs opening the sink.
  - write
```
public void write(byte[] buffer,
                  int offset,
                  int length)
           throws IOException
```
    Description copied from interface: DataSink
    
    Consumes the provided data.
    
    Specified by:
    
    write in interface DataSink
    
    Parameters:
    
    buffer - The buffer from which data should be consumed.
    
    offset - The offset of the data to consume in buffer.
    
    length - The length of the data to consume, in bytes.
    
    Throws:
    
    IOException - If an error occurs writing to the sink.
  - close
```
public void close()
           throws IOException
```
    Description copied from interface: DataSink
    
    Closes the sink.
    Note: This method must be called even if the corresponding call to DataSink.open(DataSpec) threw an IOException. See DataSink.open(DataSpec) for more details.
    
    Specified by:
    
    close in interface DataSink
    
    Throws:
    
    IOException - If an error occurs closing the sink.
