  Methods

  Modifier and Type	Method and Description
  void	close() Closes the Cursor, releasing all of its resources and making it completely invalid.
  void	deactivate() Deactivates the Cursor, making all calls on it fail until Cursor.requery() is called.
  String[]	getColumnNames() Returns a string array holding the names of all of the columns in the result set in the order in which they were listed in the result.
  int	getCount() Returns the numbers of rows in the cursor.
  Bundle	getExtras() Returns a bundle of extra values.
  IContentObserver	getObserver() Gets a SelfDataChangeOberserver that can be sent to a remote process to receive change notifications over IPC.
  void	initialize(BulkCursorDescriptor d) Initializes the adaptor.
  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.
  boolean	requery() Performs the query that created the cursor again, refreshing its contents.
  Bundle	respond(Bundle extras) This is an out-of-band way for the the user of a cursor to communicate with the cursor.

• Method Detail

  • initialize

    public void initialize(BulkCursorDescriptor d)

    Initializes the adaptor. Must be called before first use.

  • getObserver

    public IContentObserver getObserver()

    Gets a SelfDataChangeOberserver that can be sent to a remote process to receive change notifications over IPC.

    Returns:

    A SelfContentObserver hooked up to this Cursor

  • getCount

    public int getCount()

    Description copied from interface: Cursor
    Returns the numbers of rows in the cursor.

    Specified by:

    getCount in interface Cursor

    Specified by:

    getCount in class AbstractCursor

    Returns:

    the number of rows in the cursor.

  • onMove

    public boolean onMove(int oldPosition,
                 int newPosition)

    Description copied from class: AbstractCursor
    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

    Overrides:

    onMove in class AbstractCursor

    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

  • deactivate

    public void deactivate()

    Description copied from interface: Cursor
    Deactivates the Cursor, making all calls on it fail until Cursor.requery() is called. Inactive Cursors use fewer resources than active Cursors. Calling Cursor.requery() will make the cursor active again.

    Specified by:

    deactivate in interface Cursor

    Overrides:

    deactivate in class AbstractCursor

  • 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 Cursor

    Specified by:

    close in interface Closeable

    Specified by:

    close in interface AutoCloseable

    Overrides:

    close in class AbstractCursor

  • 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

    Overrides:

    requery in class AbstractCursor

    Returns:

    true if the requery succeeded, false if not, in which case the cursor becomes invalid.

  • getColumnNames

    public String[] getColumnNames()

    Description copied from interface: Cursor
    Returns a string array holding the names of all of the columns in the result set in the order in which they were listed in the result.

    Specified by:

    getColumnNames in interface Cursor

    Specified by:

    getColumnNames in class AbstractCursor

    Returns:

    the names of the columns returned in this query.

  • 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

    Overrides:

    getExtras in class AbstractCursor

    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

    Overrides:

    respond in class AbstractCursor

    Parameters:

    extras - extra values, or Bundle.EMPTY. Never null.

    Returns:

    extra values, or Bundle.EMPTY. Never null.
