Creates standard cell for application and assigns cell.textLabel.text = [[playlists objectAtIndex:(indexPath.row -1)] name].

Parameters:

createTableCellLeft UITableView which cells are generated in this function

Returns:: UITableViewCell for given parametres

Here is the call graph for this function:

Here is the caller graph for this function:

- (UITableViewCell *) createTableCellRight: (NSIndexPath *) indexPath

Creates cell for libraryTableViewRight.

Creates standard cell for application and sets it's showsReorderContor to NO if cell is "Add new score" otherwise sets it to YES;

Parameters:

createTableCellRight UITableView which cells are generated in this function

Returns:: UITableViewCell for given parametres

Here is the caller graph for this function:

- (void) didSelectRowAtLeftTable: (NSIndexPath *) indexPath

Shows libraryTableViewRight if hidden and reloads it's data.

Parameters:

didSelectRowAtLeftTable locating the new selected row

Here is the call graph for this function:

Here is the caller graph for this function:

- (void) didSelectRowAtRightTable: (NSIndexPath *) indexPath

libraryTableViewRight's implementation of tableView: indexPath.

Using gesture recognizer initialized in viewDidLoad instead to prevent popping ScorePopoverController in new UIPopoverController with every search in libraryTableViewRight.

Parameters:

didSelectRowAtRightTable locating the new selected row in tableView

Here is the caller graph for this function:

- (id) init [implementation]

Initializer for PlaylistDelegateDataSource.

Here is the caller graph for this function:

- (id) initWithMaster: (CatNiPViewController *) m

Initializer for PlaylistDelegateDataSource.

Parameters:

m	The CatNiPViewController that controls the UIView showing the library tables.

Here is the call graph for this function:

- (NSInteger) numberOfSectionsInTableView: (UITableView *) tableView

UITableViewDataSource protocol function's implementation.

Check frameworks API for details.

Parameters:

numberOfSectionsInTableView

Returns:: value 1 cause each tableView has one section

- (void) playlistActivateClicked: (id) button

Target method for playlist edit clicks.

Sends a message to the master object (ie. the CatNiPViewController displaying the library table) to open the right tableview if necessary and then displays the contents of the playlist in that tableview.

Parameters:

button The ValueButton that generated the click event

Here is the call graph for this function:

- (void) setPlaylistViewContents: (NSIndexPath *) indexPath

A helper method that sets the currently selected playlist according to the row parameter in the given NSIndexPath.

Parameters:

indexPath The index path to the playlist that will be displayed

Here is the caller graph for this function:

- (BOOL) tableView:	(UITableView *)	tableView
canEditRowAtIndexPath:	(NSIndexPath *)	indexPath

UITableViewDataSource function's implementation.

Everything is editable if LIBRARYTYPE == PLAYLISTS

Check frameworks API for details.

Parameters:

tableView	libraryTableViewRight or libraryTableViewLeft
canEditRowAtIndexPath	indexPath to cell in tableView

Returns:: YES

- (BOOL) tableView:	(UITableView *)	tableView
canMoveRowAtIndexPath:	(NSIndexPath *)	indexPath

UITableViewDataSource function's implementation.

Playlists are kept in order with sorting thus libraryTableViewLeft's cells are not movable. libraryTableViewRight's cells except "Add new score" can be moved around each other.

Check frameworks API for details.

Parameters:

tableView	libraryTableViewRight
canMoveRowAtIndexPath	indexPath to cell in tableView

Returns:: YES if tableView == libraryTableViewRight. Otherwise returns NO.

- (UITableViewCell *) tableView:	(UITableView *)	tableView
cellForRowAtIndexPath:	(NSIndexPath *)	indexPath

Mandatory UITableViewDataSource protocol's function implementation.

Calls createTableCellLeft or createTableCellRight to create a cell to return

Check frameworks API for details.

Parameters:

tableView	libraryTableViewLeft or libraryTableViewRight
cellForRowAtIndexPath	indexPath for cell to be created in tableView

Returns:: UITableViewCell for given parametres

Here is the call graph for this function:

- (void) tableView:	(UITableView *)	tableView
commitEditingStyle:	(UITableViewCellEditingStyle)	editingStyle
forRowAtIndexPath:	(NSIndexPath *)	indexPath

Deletes either whole playlist or removes one score from playlist depending on tableView.

Does not deletes LocalScoreData(s) or pdf(s) on either case.

Check frameworks API for details.

no cells with this editing style
