Tracker Struct Reference

#include <midiparser.h>

Public Member Functions
void	clear ()
	Clears all data; used by the constructor for initialization.

Public Attributes
byte *	_playPos
	A pointer to the next event to be parsed.
uint32	_playTime
	Current time in microseconds; may be in between event times.
uint32	_playTick
	Current MIDI tick; may be in between event ticks.
uint32	_lastEventTime
	The time, in microseconds, of the last event that was parsed.
uint32	_lastEventTick
	The tick at which the last parsed event occurs.
byte	_runningStatus
	Cached MIDI command, for MIDI streams that rely on implied event codes.

Detailed Description

Maintains time and position state within a MIDI stream. A single Tracker struct is used by MidiParser to keep track of its current position in the MIDI stream. The Tracker struct, however, allows alternative locations to be cached. See MidiParser::jumpToTick() for an example of tracking multiple locations within a MIDI stream. NOTE: It is important to also maintain pre-parsed EventInfo data for each Tracker location.
