CrossProcessCursorWrapper

public class CrossProcessCursorWrapper extends android.database.CursorWrapper implements android.database.CrossProcessCursor
Cursor wrapper that implements {@link CrossProcessCursor}.

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

This wrapper can be used to adapt an ordinary {@link Cursor} into a {@link CrossProcessCursor}.
