CrossProcessCursorWrapper

Kotlin |Java

open class CrossProcessCursorWrapper : CursorWrapper, CrossProcessCursor

kotlin.Any
↳	android.database.CursorWrapper
	↳	android.database.CrossProcessCursorWrapper

Cursor wrapper that implements CrossProcessCursor.

If the wrapped cursor implements CrossProcessCursor, then the wrapper delegates fillWindow, getWindow() and onMove to it. Otherwise, the wrapper provides default implementations of these methods that traverse the contents of the cursor similar to AbstractCursor.fillWindow.

This wrapper can be used to adapt an ordinary Cursor into a CrossProcessCursor.

Added in API level 15

open fun fillWindow(
    position: Int, 
    window: CursorWindow!
): Unit

Parameters
`position`	Int: The zero-based index of the first row to copy into the window.
`window`	CursorWindow!: The window to fill.

getWindow

Added in API level 15

open fun getWindow(): CursorWindow!

Return
`CursorWindow!`	The pre-filled window, or null if none.

onMove

Added in API level 15

open fun onMove(
