Inheritance diagram for juce::TimedCallback:

## Public Member Functions

| TimedCallback (std::function< void()> callbackIn)
| ~TimedCallback () noexcept override
void | startTimer (int intervalInMilliseconds) noexcept
void | startTimerHz (int timerFrequencyHz) noexcept
void | stopTimer () noexcept
bool | isTimerRunning () const noexcept
int | getTimerInterval () const noexcept

## Detailed Description

Utility class wrapping a single non-null callback called by a Timer.

You can use the usual Timer functions to start and stop the TimedCallback. Deleting the TimedCallback will automatically stop the underlying Timer.

With this class you can use the Timer facility without inheritance.

## Constructor & Destructor Documentation

## TimedCallback()

juce::TimedCallback::TimedCallback | ( | std::function< void()> | callbackIn | ) |

inline explicit

Constructor. The passed in callback must be non-null.

Definition at line 43 of file juce_TimedCallback.h.

## ~TimedCallback()

juce::TimedCallback::~TimedCallback | ( |  | ) |

inline override noexcept

Destructor.

Definition at line 50 of file juce_TimedCallback.h.

## Member Function Documentation

## getTimerInterval()

int juce::Timer::getTimerInterval | ( |  | ) | const

inline noexcept

Returns the timer's interval.

Returns
  the timer's interval in milliseconds if it's running, or 0 if it's not.

Definition at line 116 of file juce_Timer.h.

## isTimerRunning()

bool juce::Timer::isTimerRunning | ( |  | ) | const

inline noexcept

Returns true if the timer is currently running.

Definition at line 111 of file juce_Timer.h.

## startTimer()

void juce::Timer::startTimer | ( | int | intervalInMilliseconds | ) |

noexcept

Starts the timer and sets the length of interval required.

If the timer is already started, this will reset it, so the time between calling this method and the next timer callback will not be less than the interval length passed in.

Parameters

  intervalInMilliseconds | the interval to use (any value less than 1 will be rounded up to 1)

Definition at line 90 of file juce_Timer.cpp.

## startTimerHz()

void juce::Timer::startTimerHz | ( | int | timerFrequencyHz | ) |

noexcept

Starts the timer with an interval specified in Hertz. This is effectively the same as calling startTimer (1000 / timerFrequencyHz).

Definition at line 95 of file juce_Timer.cpp.

## stopTimer()

void juce::Timer::stopTimer | ( |  | ) |

noexcept

Stops the timer.

No more timer callbacks will be triggered after this method returns.

Note that if you call this from a background thread while the message-thread is already in the middle of your callback, then this method will cancel any future timer callbacks, but it will return without waiting for the current one to finish. The current callback will continue, possibly still running some of your timer code after this method has returned.
