Field Detail

• FLAG_ALLOW_GZIP

  public static final int FLAG_ALLOW_GZIP

  Deprecated.
  Allows an underlying network stack to request that the server use gzip compression.

  Should not typically be set if the data being requested is already compressed (e.g. most audio and video requests). May be set when requesting other data.

  When a DataSource is used to request data with this flag set, and if the DataSource does make a network request, then the value returned from DataSource.open(DataSpec) will typically be C.LENGTH_UNSET. The data read from DataReader.read(byte[], int, int) will be the decompressed data.

  Constant Field Values

• FLAG_DONT_CACHE_IF_LENGTH_UNKNOWN

  public static final int FLAG_DONT_CACHE_IF_LENGTH_UNKNOWN

  Deprecated.
  Prevents caching if the length cannot be resolved when the DataSource is opened.

  See Also:

  Constant Field Values

• FLAG_ALLOW_CACHE_FRAGMENTATION

  public static final int FLAG_ALLOW_CACHE_FRAGMENTATION

  Deprecated.
  Allows fragmentation of this request into multiple cache files, meaning a cache eviction policy will be able to evict individual fragments of the data. Depending on the cache implementation, setting this flag may also enable more concurrent access to the data (e.g. reading one fragment whilst writing another).

  See Also:

  Constant Field Values

• FLAG_MIGHT_NOT_USE_FULL_NETWORK_SPEED

  public static final int FLAG_MIGHT_NOT_USE_FULL_NETWORK_SPEED

  Deprecated.
  Indicates there are known external factors that might prevent the data from being loaded at full network speed (e.g. server throttling or unfinished live media chunks).

  See Also:

  Constant Field Values

• HTTP_METHOD_GET

  public static final int HTTP_METHOD_GET

  Deprecated.
  HTTP GET method.

  See Also:

  Constant Field Values

• HTTP_METHOD_POST

  public static final int HTTP_METHOD_POST

  Deprecated.
  HTTP POST method.

  See Also:

  Constant Field Values

• HTTP_METHOD_HEAD

  public static final int HTTP_METHOD_HEAD

  Deprecated.
  HTTP HEAD method.

  See Also:

  Constant Field Values

• uri

  public final Uri uri

  Deprecated.
  A Uri from which data belonging to the resource can be read.

• uriPositionOffset

  public final long uriPositionOffset

  Deprecated.
  The offset of the data located at uri within the resource.

  Equal to 0 unless uri provides access to a subset of the resource. As an example, consider a resource that can be requested over the network and is 1000 bytes long. If uri points to a local file that contains just bytes [200-300], then this field will be set to 200.

  This field can be ignored except for in specific circumstances where the absolute position in the resource is required in a DataSource chain. One example is when a DataSource needs to decrypt the content as it's read. In this case the absolute position in the resource is typically needed to correctly initialize the decryption algorithm.

• httpMethod

  public final @com.google.android.exoplayer2.upstream.DataSpec.HttpMethod int httpMethod

  Deprecated.
  The HTTP method to use when requesting the data. This value will be ignored by non-HTTP DataSource implementations.

• httpBody

  @Nullable
  public final byte[] httpBody

  Deprecated.
  The HTTP request body, null otherwise. If the body is non-null, then httpBody.length will be non-zero.

• httpRequestHeaders

  public final Map<String,​String> httpRequestHeaders

  Deprecated.
  Additional HTTP headers to use when requesting the data.

  Note: This map is for additional headers specific to the data being requested. It does not include headers that are set directly by HttpDataSource implementations. In particular, this means the following headers are not included:

  • Range: HttpDataSource implementations derive the Range header from position and length.
  • Accept-Encoding: HttpDataSource implementations derive the Accept-Encoding header based on whether flags includes FLAG_ALLOW_GZIP.
  • User-Agent: HttpDataSource implementations set the User-Agent header directly.
  • Other headers set at the HttpDataSource layer. I.e., headers set using HttpDataSource.setRequestProperty(String, String), and using HttpDataSource.Factory.setDefaultRequestProperties(Map).

• absoluteStreamPosition

  @Deprecated
  public final long absoluteStreamPosition

  Deprecated.

  Use position except for specific use cases where the absolute position within the resource is required within a DataSource chain. Where the absolute position is required, use uriPositionOffset + position.
  The absolute position of the data in the resource.

• position

  public final long position

  Deprecated.
  The position of the data when read from uri.

• length

  public final long length

  Deprecated.
  The length of the data, or C.LENGTH_UNSET.

• key

  @Nullable
  public final String key

  Deprecated.
  A key that uniquely identifies the resource. Used for cache indexing. May be null if the data spec is not intended to be used in conjunction with a cache.

• flags

  public final @com.google.android.exoplayer2.upstream.DataSpec.Flags int flags

  Deprecated.
  Request flags.

• customData

  @Nullable
  public final Object customData

  Deprecated.
  Application specific data.

  This field is intended for advanced use cases in which applications require the ability to attach custom data to DataSpec instances. The custom data should be immutable.
