public abstract class AbstractCursor
 implements Cursor
                    
```
This is an abstract cursor class that handles a lot of the common code that all cursors need to deal with and is provided for convenience reasons.

getPosition
```

```

moveToPosition

 final boolean moveToPosition(int position)

onMove
```
 abstract boolean onMove(int oldPosition, int newPosition)
```
This function is called every time the cursor is successfully scrolledto a new position, giving the subclass a chance to update any state itmay have. If it returns false the move function will also do so and thecursor will scroll to the beforeFirst position.
This function should be called by methods such as moveToPosition,so it will typically not be called from outside of the cursor class itself.

Parameters:

oldPosition - The position that we're moving from.

newPosition - The position that we're moving to.

move
```
 final boolean move(int offset)
```

moveToFirst
```
 final boolean moveToFirst()
```

moveToLast
```
 final boolean moveToLast()
```

moveToNext
```
 final boolean moveToNext()
```

moveToPrevious
```
 final boolean moveToPrevious()
```

isFirst
```
 final boolean isFirst()
```

isLast
```
 final boolean isLast()
```

isBeforeFirst
```
 final boolean isBeforeFirst()
```

isAfterLast
```
 final boolean isAfterLast()
```

getColumnIndex
```
 int getColumnIndex(String columnName)
```

getColumnIndexOrThrow

 int getColumnIndexOrThrow(String columnName)

getColumnName
```
 String getColumnName(int columnIndex)
```

registerContentObserver

 void registerContentObserver(ContentObserver observer)

unregisterContentObserver

 void unregisterContentObserver(ContentObserver observer)

registerDataSetObserver

 void registerDataSetObserver(DataSetObserver observer)

unregisterDataSetObserver

 void unregisterDataSetObserver(DataSetObserver observer)

setNotificationUri
```
 void setNotificationUri(ContentResolver cr, Uri notifyUri)
```
Specifies a content URI to watch for changes.

Parameters:

cr - The content resolver from the caller's context.

notifyUri - The URI to watch for changes.

getNotificationUri
```
 Uri getNotificationUri()
```

getWantsAllOnMoveCalls
```
 boolean getWantsAllOnMoveCalls()
```

setExtras
```
 void setExtras(Bundle extras)
```

getExtras
```
 Bundle getExtras()
```

respond
```
 Bundle respond(Bundle extras)
```
