### Inherited methods

From [androidx.media3.datasource.DataSource.Factory](https://developer.android.com/reference/androidx/media3/datasource/DataSource.Factory) `abstract https://developer.android.com/reference/androidx/media3/datasource/DataSource` `@https://developer.android.com/reference/androidx/media3/common/util/UnstableApi
https://developer.android.com/reference/androidx/media3/datasource/DataSource.Factory#createDataSource()()`

Creates a `https://developer.android.com/reference/androidx/media3/datasource/DataSource` instance.

## Public constructors

### BaseFactory

```
public BaseFactory()
```

## Public methods

### createDataSource

```
public final HttpDataSource createDataSource()
```

Creates a `https://developer.android.com/reference/androidx/media3/datasource/DataSource` instance.

### setDefaultRequestProperties

```
@CanIgnoreReturnValue
public final HttpDataSource.Factory setDefaultRequestProperties(
    Map<String, String> defaultRequestProperties
)
```

Sets the default request headers for `https://developer.android.com/reference/androidx/media3/datasource/HttpDataSource` instances created by the factory.

The new request properties will be used for future requests made by `https://developer.android.com/reference/androidx/media3/datasource/HttpDataSource` created by the factory, including instances that have already been created. Modifying the `defaultRequestProperties` map after a call to this method will have no effect, and so it's necessary to call this method again each time the request properties need to be updated.

| Parameters |
|---|---|
| `https://developer.android.com/reference/java/util/Map.html<https://developer.android.com/reference/java/lang/String.html, https://developer.android.com/reference/java/lang/String.html> defaultRequestProperties` | The default request properties. |

| Returns |
|---|---|
| `https://developer.android.com/reference/androidx/media3/datasource/HttpDataSource.Factory` | This factory. |

## Protected methods

### createDataSourceInternal

```
protected abstract HttpDataSource createDataSourceInternal(
    HttpDataSource.RequestProperties defaultRequestProperties
)
```

Called by `https://developer.android.com/reference/androidx/media3/datasource/HttpDataSource.BaseFactory#createDataSource()` to create a `https://developer.android.com/reference/androidx/media3/datasource/HttpDataSource` instance.

| Parameters |
|---|---|
| `https://developer.android.com/reference/androidx/media3/datasource/HttpDataSource.RequestProperties defaultRequestProperties` | The default `RequestProperties` to be used by the `https://developer.android.com/reference/androidx/media3/datasource/HttpDataSource` instance. |

| Returns |
|---|---|
| `https://developer.android.com/reference/androidx/media3/datasource/HttpDataSource` | A `https://developer.android.com/reference/androidx/media3/datasource/HttpDataSource` instance. |
