Detailed Description
MKNoteFilter is an abstract class that combines the functionality it inherits from MKInstrument with the protocol defined in the MKPerformer class.MKNoteFilter is an abstract class that combines the functionality it inherits from MKInstrument with the protocol defined in the MKPerformer class. MKNoteFilter objects can both receive and send MKNotes; they're interposed between MKPerformers and MKInstruments to create a MKNote processing pipeline. The subclass responsibility realizeNote:fromNoteReceiver: is passed on to MKNoteFilter subclasses. Keep in mind that notes must be copied on write or store.
Member Function Documentation
| - (id) init |
| - (NSArray *) noteSenders |
Returns a copy of the receiver's NSArray of MKNoteSenders.
- Returns:
- Returns an NSArray instance.
| - (BOOL) isNoteSenderPresent: | (MKNoteSender *) | aNoteSender |
Returns YES if aNoteSender is one of the receiver's MKNoteSenders.
- Parameters:
-
aNoteSender is an MKNoteSender instance.
- Returns:
- Returns a BOOL. Otherwise returns NO.
| - (id) copyWithZone: | (NSZone *) | zone |
Creates and returns a MKNoteFilter as a copy of the receiver.
- Parameters:
-
zone is a NSZone.
- Returns:
- Returns an id. The new object contains copies of the receiver's MKNoteSenders and MKNoteReceivers.
Reimplemented from MKInstrument.
| - (id) releaseNoteSenders |
Removes and frees the receiver's MKNoteSenders.
- Returns:
- Returns an id. Returns the receiver.
| - (id) removeNoteSenders |
Removes all the receiver's MKNoteSenders.
- Returns:
- Returns an id. Returns the receiver.
| - (MKNoteSender *) noteSender |
Returns the receiver's first MKNoteSender.
- Returns:
- Returns an MKNoteSender instance. This is method should only by invoked if the receiver only contains one MKNoteSender or if you don't care which MKNoteSender you get. If there are currently no MKNoteSenders, this method creates and adds a MKNoteSender.
| - (MKNoteSender *) addNoteSender: | (MKNoteSender *) | aNoteSender |
Removes aNoteSender from its present owner (if any) and adds it to the receiver.
- Parameters:
-
aNoteSender is an MKNoteSender instance.
- Returns:
- Returns an MKNoteSender instance. Returns aNoteSender. If the receiver is in performance, or if aNoteSender is already a member of the receiver, does nothing and returns nil.
| - (MKNoteSender *) removeNoteSender: | (MKNoteSender *) | aNoteSender |
Removes aNoteSender from the receiver's NSArray of MKNoteSenders.
- Parameters:
-
aNoteSender is an MKNoteSender instance.
- Returns:
- Returns an MKNoteSender instance. Returns aNoteSender. If the receiver is in a performance, does nothing and returns nil.
