Descriptor bit used with[describeContents()](https://developer.android.com/reference/kotlin/android/os/Parcelable#describeContents()): indicates that the Parcelable object's flattened representation includes a file descriptor.

Flag for use with[writeToParcel](https://developer.android.com/reference/kotlin/android/os/Parcelable#writeToParcel(android.os.Parcel,%20kotlin.Int)): the object being written is a return value, that is the result of a function such as "`Parcelable someFunction()`", "`void someFunction(out Parcelable)`", or "`void someFunction(inout Parcelable)`". Some implementations may want to release resources at this point.

| ## Public constructors ### WorkSource Added in[API level 9](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) ``` WorkSource() ``` Create an empty work source. ### WorkSource Added in[API level 9](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) ``` WorkSource(orig: WorkSource!) ``` Create a new WorkSource that is a copy of an existing one. If orig is null, an empty WorkSource is created. ## Public methods ### add Added in[API level 9](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) ``` open fun add(other: WorkSource!): Boolean ``` Merge the contents of other WorkSource in to this one. | Parameters || |---------|--------------------------------------------------------------------------------------------------------------------------------------------| | `other` | [WorkSource](https://developer.android.com/reference/kotlin/android/os/WorkSource#)!:The other WorkSource whose contents are to be merged. | | Return || |------------------------------------------------------------------------------------|---------------------------------------------| | [Boolean](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-boolean/index.html) | Returns true if any new sources were added. | ### clear Added in[API level 9](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) ``` open fun clear(): Unit ``` Clear this WorkSource to be empty. ### describeContents Added in[API level 9](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) ``` open fun describeContents(): Int ``` | Return || |----------------------------------------------------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | [Int](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-int/index.html) | a bitmask indicating the set of special object types marshaled by this Parcelable object instance.

The`equals`method implements an equivalence relation on non-null object references: - It is*reflexive* : for any non-null reference value`x`,`x.equals(x)`should return`true`. - It is*symmetric* : for any non-null reference values`x`and`y`,`x.equals(y)`should return`true`if and only if`y.equals(x)`returns`true`. - It is*transitive* : for any non-null reference values`x`,`y`, and`z`, if`x.equals(y)`returns`true`and`y.equals(z)`returns`true`, then`x.equals(z)`should return`true`. - It is*consistent* : for any non-null reference values`x`and`y`, multiple invocations of`x.equals(y)`consistently return`true`or consistently return`false`, provided no information used in`equals`comparisons on the objects is modified. - For any non-null reference value`x`,`x.equals(null)`should return`false`. An equivalence relation partitions the elements it operates on into*equivalence classes*; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes. | Parameters || |-------|---------------------------------------------| | `obj` | the reference object with which to compare. | | `o` | This value may be`null`. | | Return || |------------------------------------------------------------------------------------|------------------------------------------------------------------------| | [Boolean](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-boolean/index.html) | `true`if this object is the same as the obj argument;`false`otherwise. | ### hashCode Added in[API level 9](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) ``` open fun hashCode(): Int ``` | Return || |----------------------------------------------------------------------------|------------------------------------| | [Int](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-int/index.html) | a hash code value for this object. | ### remove Added in[API level 9](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) ``` open fun remove(other: WorkSource!): Boolean ``` ### set Added in[API level 9](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) ``` open fun set(other: WorkSource!): Unit ``` Replace the current contents of this work source with the given work source.
