public long open([DataSpec](DataSpec.html "class in com.google.android.exoplayer2.upstream")dataSpec)
throws[UdpDataSource.UdpDataSourceException](UdpDataSource.UdpDataSourceException.html "class in com.google.android.exoplayer2.upstream")
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`](DataSpec.html#position) is within the resource, but the [`requested length`](DataSpec.html#length) extends beyond the end of the resource, then [`DataSource.open(com.google.android.exoplayer2.upstream.DataSpec)`](DataSource.html#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)`](DataReader.html#read(byte%5B%5D,int,int)).
- If the [`requested position`](DataSpec.html#position) is equal to the length of the resource, then [`DataSource.open(com.google.android.exoplayer2.upstream.DataSpec)`](DataSource.html#open(com.google.android.exoplayer2.upstream.DataSpec)) will succeed, and [`DataReader.read(byte[], int, int)`](DataReader.html#read(byte%5B%5D,int,int)) will immediately return [`C.RESULT_END_OF_INPUT`](../C.html#RESULT_END_OF_INPUT).
- If the [`requested position`](DataSpec.html#position) is greater than the length of the resource, then [`DataSource.open(com.google.android.exoplayer2.upstream.DataSpec)`](DataSource.html#open(com.google.android.exoplayer2.upstream.DataSpec)) will throw an [`IOException`](https://developer.android.com/reference/java/io/IOException.html "class or interface in java.io") for which [`DataSourceException.isCausedByPositionOutOfRange(java.io.IOException)`](DataSourceException.html#isCausedByPositionOutOfRange(java.io.IOException)) will be `true`.
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:UdpDataSource.UdpDataSourceException

public int read(byte[] buffer,
int offset,
int length)
throws[UdpDataSource.UdpDataSourceException](UdpDataSource.UdpDataSourceException.html "class in com.google.android.exoplayer2.upstream")
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.
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:UdpDataSource.UdpDataSourceException

@Nullable
public[Uri](https://developer.android.com/reference/android/net/Uri.html "class or interface in android.net")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.
Returns:The Uri from which data is being read, or null if the source is not open.
-
public void close()
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.
-
public int getLocalPort()
Deprecated.
Returns the local port number opened for the UDP connection, or UDP_PORT_UNSET if no connection is open
