• AesCipherDataSource

  public AesCipherDataSource​(byte[] secretKey,
                             DataSource upstream)

  Deprecated.

Method Detail

• addTransferListener

  public void addTransferListener​(TransferListener transferListener)

  Deprecated.
  Description copied from interface: DataSource
  Adds a TransferListener to listen to data transfers. This method is not thread-safe.

  Specified by:

  addTransferListener in interface DataSource

  Parameters:

  transferListener - A TransferListener.

• open

  public long open​(DataSpec dataSpec)
            throws IOException

  Deprecated.
  Description copied from interface: DataSource
  Opens the source to read the specified data. If an IOException is thrown, callers must still call DataSource.close() to ensure that any partial effects of the invocation are cleaned up.

  The following edge case behaviors apply:

  • If the requested position is within the resource, but the requested length extends beyond the end of the resource, then DataSource.open(com.google.android.exoplayer2.upstream.DataSpec) will succeed and data from the requested position to the end of the resource will be made available through DataReader.read(byte[], int, int).
  • If the requested position is equal to the length of the resource, then DataSource.open(com.google.android.exoplayer2.upstream.DataSpec) will succeed, and DataReader.read(byte[], int, int) will immediately return C.RESULT_END_OF_INPUT.
  • If the requested position is greater than the length of the resource, then DataSource.open(com.google.android.exoplayer2.upstream.DataSpec) will throw an IOException for which DataSourceException.isCausedByPositionOutOfRange(java.io.IOException) will be true.

  Specified by:

  open in interface DataSource

  Parameters:

  dataSpec - Defines the data to be read.

  Returns:

  The number of bytes that can be read from the opened source. For unbounded requests (i.e., requests where DataSpec.length equals C.LENGTH_UNSET) this value is the resolved length of the request, or C.LENGTH_UNSET if the length is still unresolved. For all other requests, the value returned will be equal to the request's DataSpec.length.

  Throws:

  IOException - If an error occurs opening the source. DataSourceException can be thrown or used as a cause of the thrown exception to specify the reason of the error.

• read

  public int read​(byte[] buffer,
                  int offset,
                  int length)
           throws IOException

  Deprecated.
  Description copied from interface: DataReader
  Reads up to length bytes of data from the input.

  If readLength is zero then 0 is returned. Otherwise, if no data is available because the end of the opened range has been reached, then C.RESULT_END_OF_INPUT is returned. Otherwise, the call will block until at least one byte of data has been read and the number of bytes read is returned.

  Specified by:

  read in interface DataReader

  Parameters:

  buffer - A target array into which data should be written.

  offset - The offset into the target array at which to write.

  length - The maximum number of bytes to read from the input.

  Returns:

  The number of bytes read, or C.RESULT_END_OF_INPUT if the input has ended. This may be less than length because the end of the input (or available data) was reached, the method was interrupted, or the operation was aborted early for another reason.

  Throws:

  IOException - If an error occurs reading from the input.

• getUri

  @Nullable
  public Uri getUri()

  Deprecated.
  Description copied from interface: DataSource
  When the source is open, returns the Uri from which data is being read. The returned Uri will be identical to the one passed DataSource.open(DataSpec) in the DataSpec unless redirection has occurred. If redirection has occurred, the Uri after redirection is returned.

  Specified by:

  getUri in interface DataSource

  Returns:

  The Uri from which data is being read, or null if the source is not open.

• getResponseHeaders

  public Map<String,​List<String>> getResponseHeaders()

  Deprecated.
  Description copied from interface: DataSource
  When the source is open, returns the response headers associated with the last DataSource.open(com.google.android.exoplayer2.upstream.DataSpec) call. Otherwise, returns an empty map.

  Key look-up in the returned map is case-insensitive.

  Specified by:

  getResponseHeaders in interface DataSource

• close

  public void close()
             throws IOException

  Deprecated.
  Description copied from interface: DataSource
  Closes the source. This method must be called even if the corresponding call to DataSource.open(DataSpec) threw an IOException.

  Specified by:

  close in interface DataSource

  Throws:

  IOException - If an error occurs closing the source.
