# Class ModifierDataSourceFactory

java.lang.Object
com.castlabs.android.network.ModifierDataSourceFactory

All Implemented Interfaces:
  `DataSourceFactory`, `com.google.android.exoplayer2.upstream.DataSource.Factory`

public class ModifierDataSourceFactory extends Object implements DataSourceFactory
Delegating data source factory that will trigger all `RequestModifier`s registered with the player controller.

Note that you usually do not have to use this class explicitly. The `PlayerController` will automatically create delegate instances for the different data request types.

Since:
  4.1.2

  - ### ModifierDataSourceFactory

    public ModifierDataSourceFactory(@NonNull DataSourceFactory delegate, int type, @NonNull List<RequestModifier> requestModifiers, @NonNull List<ResponseModifier> responseModifiers)
    Create a new instance of this data source factory
    Parameters:
      `delegate` - The delegate that this factory wraps around
      `type` - The request type that will be send to the request modifier plugin. Should be one of `Request.DATA_TYPE_MANIFEST`, `Request.DATA_TYPE_SEGMENT`, or `Request.DATA_TYPE_OTHER`
      `requestModifiers` - The list of request modifier plugins
      `responseModifiers` - The list of response modifier plugins

  - ### ModifierDataSourceFactory

    public ModifierDataSourceFactory(@NonNull DataSourceFactory delegate, int type, @NonNull List<RequestModifier> requestModifiers, @NonNull List<ResponseModifier> responseModifiers, @NonNull NetworkConfiguration networkConfiguration, @Nullable RequestModifier.Listener requestModifierListener)
    Create a new instance of this data source factory
    Parameters:
      `delegate` - The delegate that this factory wraps around
      `type` - The request type that will be send to the request modifier plugin. Should be one of `Request.DATA_TYPE_MANIFEST`, `Request.DATA_TYPE_SEGMENT`, or `Request.DATA_TYPE_OTHER`
      `requestModifiers` - The list of request modifier plugins
      `responseModifiers` - The list of response modifier plugins
      `networkConfiguration` - The network configuration to use for requests
      `requestModifierListener` - The listener for request modifier events

- ## Method Details

  - ### forceDataSourceWrap

    public void forceDataSourceWrap(boolean forceSourceWrap)
    Force the data source to be wrapped even if no request modifiers are present. This is useful when the request modifiers are added later.
    Parameters:
      `forceSourceWrap` - True if the data source should be wrapped even if no request modifiers are present

  - ### createDataSource

    public com.google.android.exoplayer2.upstream.DataSource createDataSource()
    Specified by:
      `createDataSource` in interface `com.google.android.exoplayer2.upstream.DataSource.Factory`

  - ### createDataSource

    public com.google.android.exoplayer2.upstream.DataSource createDataSource(int requestType)
    Description copied from interface: `DataSourceFactory`
    Creates a data source for the given request type
    Specified by:
      `createDataSource` in interface `DataSourceFactory`
    Parameters:
      `requestType` - The request type
    Returns:
      dataSource the data source

  - ### addHeaderParameter

    public void addHeaderParameter(@NonNull String key, @NonNull String value)
    Description copied from interface: `DataSourceFactory`
