A[CursorWindow](https://developer.android.com/reference/kotlin/android/database/CursorWindow#)is read-write when initially created and used locally. When sent to a remote process (by writing it to a[Parcel](https://developer.android.com/reference/kotlin/android/os/Parcel.html#)), the remote process receives a read-only view of the cursor window. Typically the cursor window will be allocated by the producer, filled with data, and then sent to the consumer for reading. ## Summary | Inherited constants || |---|---| | From class[Parcelable](https://developer.android.com/reference/kotlin/android/os/Parcelable.html#) |----------------------------------------------------------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | [Int](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-int/index.html) | [CONTENTS_FILE_DESCRIPTOR](https://developer.android.com/reference/kotlin/android/os/Parcelable.html#CONTENTS_FILE_DESCRIPTOR:kotlin.Int)

Flag for use with[writeToParcel](https://developer.android.com/reference/kotlin/android/os/Parcelable.html#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.
