Detailed Description

Iterator over the MidiEvents in a Playable.

This is an iterator that moves over every MidiEvent in a Playable object. Each MidiEvent are delivered in time order. This is a use of the 'Iterator' design pattern in the GoF book.

Each kind of Playable object will provide an implementation of the PlayableIterator interface that knows how to iterate over that kind of object.

Constructor & Destructor Documentation

TSE3::PlayableIterator::PlayableIterator (   )

Create a PlayableIterator. Client code will never call this member function. Important note Derived classes must attach themselves to the parent Playable object as listeners, and then implement properly.

virtual TSE3::PlayableIterator::~PlayableIterator (   )  [virtual]

Member Function Documentation

const MidiEvent& TSE3::PlayableIterator::operator * (   )  const [inline]

Returns the next MidiEvent in the iterator Returns: Next MidiEvent See also: operator->

const MidiEvent* TSE3::PlayableIterator::operator-> (   )  const [inline]

Returns the next MidiEvent in the iterator Returns: Next MidiEvent See also: operator*

bool TSE3::PlayableIterator::more (   )  const [inline]

Returns whether there are any more events to come; i.e. whether ++ is valid on this object. Returns: Whether there are any more events

virtual void TSE3::PlayableIterator::moveTo (  Clock   )  [inline, virtual]

Moves the iterator to the given time position. Parameters: c  Time to move iterator to.

PlayableIterator& TSE3::PlayableIterator::operator++ (   )

Increments the iterator, so that it will return the next MidiEvent in the Playable.

virtual void TSE3::PlayableIterator::getNextEvent (   )  [protected, pure virtual]
