    Specified by:
    
    deactivate in interface Cursor
  - onDeactivateOrClose
```
protected void onDeactivateOrClose()
```
  - requery
```
public boolean requery()
```
    Description copied from interface: Cursor
    
    Performs the query that created the cursor again, refreshing its contents. This may be done at any time, including after a call to Cursor.deactivate(). Since this method could execute a query on the database and potentially take a while, it could cause ANR if it is called on Main (UI) thread. A warning is printed if this method is being executed on Main thread.
    
    Specified by:
    
    requery in interface Cursor
    
    Returns:
    
    true if the requery succeeded, false if not, in which case the cursor becomes invalid.

    true if the cursor is closed.
  - close
```
public void close()
```
    Description copied from interface: Cursor
    
    Closes the Cursor, releasing all of its resources and making it completely invalid. Unlike Cursor.deactivate() a call to Cursor.requery() will not make the Cursor valid again.
    
    Specified by:
    
    close in interface AutoCloseable
    
    Specified by:
    
    close in interface Closeable
    
    Specified by:

  - onMove
```
public boolean onMove(int oldPosition,
                      int newPosition)
```
    This function is called every time the cursor is successfully scrolled to a new position, giving the subclass a chance to update any state it may have. If it returns false the move function will also do so and the cursor will scroll to the beforeFirst position.
    
    Specified by:
    
    onMove in interface CrossProcessCursor
    
    Parameters:
    
    oldPosition - the position that we're moving from
    
    newPosition - the position that we're moving to
    
    Returns:
    
    true if the move is successful, false otherwise

```
    Description copied from interface: Cursor
    
    Retrieves the requested column text and stores it in the buffer provided. If the buffer size is not sufficient, a new char buffer will be allocated and assigned to CharArrayBuffer.data
    
    Specified by:
    
    copyStringToBuffer in interface Cursor
    
    Parameters:
    
    columnIndex - the zero-based index of the target column. if the target column is null, return buffer
    
    buffer - the buffer to copy the text into.
  - getPosition
```
public final int getPosition()
```
    Description copied from interface: Cursor
    
    Returns the current position of the cursor in the row set. The value is zero-based. When the row set is first returned the cursor will be at positon -1, which is before the first row. After the last row is returned another call to next() will leave the cursor past the last entry, at a position of count().
    
    Specified by:
    
    getPosition in interface Cursor
    
    Returns:
    
    the current cursor position.
  - moveToPosition
```
public final boolean moveToPosition(int position)
```
    Description copied from interface: Cursor
    
    Move the cursor to an absolute position. The valid range of values is -1 <= position <= count.
    This method will return true if the request destination was reachable, otherwise, it returns false.
    
    Specified by:
    
    moveToPosition in interface Cursor
    
    Parameters:
    
    position - the zero-based position to move to.
    
    Returns:
    
    whether the requested move fully succeeded.
  - fillWindow
```
public void fillWindow(int position,
                       CursorWindow window)
```
    Description copied from interface: CrossProcessCursor
    
    Copies cursor data into the window.
    Clears the window and fills it with data beginning at the requested row position until all of the data in the cursor is exhausted or the window runs out of space.
    The filled window uses the same row indices as the original cursor. For example, if you fill a window starting from row 5 from the cursor, you can query the contents of row 5 from the window just by asking it for row 5 because there is a direct correspondence between the row indices used by the cursor and the window.
    The current position of the cursor, as returned by Cursor.getPosition(), is not changed by this method.
    
    Specified by:
    
    fillWindow in interface CrossProcessCursor
    
    Parameters:
    
    position - The zero-based index of the first row to copy into the window.
    
    window - The window to fill.
  - move
```
public final boolean move(int offset)
```
    Description copied from interface: Cursor
    
    Move the cursor by a relative amount, forward or backward, from the current position. Positive offsets move forwards, negative offsets move backwards. If the final position is outside of the bounds of the result set then the resultant position will be pinned to -1 or count() depending on whether the value is off the front or end of the set, respectively.
    This method will return true if the requested destination was reachable, otherwise, it returns false. For example, if the cursor is at currently on the second entry in the result set and move(-5) is called, the position will be pinned at -1, and false will be returned.
    
    Specified by:
    
    move in interface Cursor
    
    Parameters:
    
    offset - the offset to be applied from the current position.
    
    Returns:
    
    whether the requested move fully succeeded.

  - setExtras
```
public void setExtras(Bundle extras)
```
    Description copied from interface: Cursor
    
    Sets a Bundle that will be returned by Cursor.getExtras().
    
    Specified by:
    
    setExtras in interface Cursor
    
    Parameters:
    
    extras - Bundle to set, or null to set an empty bundle.
  - getExtras
```
public Bundle getExtras()
```
    Description copied from interface: Cursor
    
    Returns a bundle of extra values. This is an optional way for cursors to provide out-of-band metadata to their users. One use of this is for reporting on the progress of network requests that are required to fetch data for the cursor.
    These values may only change when requery is called.
    
    Specified by:
    
    getExtras in interface Cursor
    
    Returns:
    
    cursor-defined values, or Bundle.EMPTY if there are no values. Never null.
  - respond
```
public Bundle respond(Bundle extras)
```
    Description copied from interface: Cursor
    
    This is an out-of-band way for the the user of a cursor to communicate with the cursor. The structure of each bundle is entirely defined by the cursor.
    One use of this is to tell a cursor that it should retry its network request after it reported an error.
    
    Specified by:
    
    respond in interface Cursor
    
    Parameters:
    
    extras - extra values, or Bundle.EMPTY. Never null.
    
    Returns:
    
    extra values, or Bundle.EMPTY. Never null.
  - isFieldUpdated
```
@Deprecated
protected boolean isFieldUpdated(int columnIndex)
```
    Deprecated.
    Always returns false since Cursors do not support updating rows
  - getUpdatedField
```
@Deprecated
protected Object getUpdatedField(int columnIndex)
```
    Deprecated.
    Always returns null since Cursors do not support updating rows
  - checkPosition
```
protected void checkPosition()
```
    This function throws CursorIndexOutOfBoundsException if the cursor position is out of bounds. Subclass implementations of the get functions should call this before attempting to retrieve data.
    
    Throws:
    
    CursorIndexOutOfBoundsException
  - finalize
```
protected void finalize()
```
    Description copied from class: Object
    
    Invoked when the garbage collector has detected that this instance is no longer reachable. The default implementation does nothing, but this method can be overridden to free resources.
    Note that objects that override finalize are significantly more expensive than objects that don't. Finalizers may be run a long time after the object is no longer reachable, depending on memory pressure, so it's a bad idea to rely on them for cleanup. Note also that finalizers are run on a single VM-wide finalizer thread, so doing blocking work in a finalizer is a bad idea. A finalizer is usually only necessary for a class that has a native peer and needs to call a native method to destroy that peer. Even then, it's better to provide an explicit close method (and implement Closeable), and insist that callers manually dispose of instances. This works well for something like files, but less well for something like a BigInteger where typical calling code would have to deal with lots of temporaries. Unfortunately, code that creates lots of temporaries is the worst kind of code from the point of view of the single finalizer thread.
    If you must use finalizers, consider at least providing your own ReferenceQueue and having your own thread process that queue.
    Unlike constructors, finalizers are not automatically chained. You are responsible for calling super.finalize() yourself.
    Uncaught exceptions thrown by finalizers are ignored and do not terminate the finalizer thread. See Effective Java Item 7, "Avoid finalizers" for more.
    
    Overrides:
    
    finalize in class Object
