public class UITimer

Object
UITimer

Simple timer callback that is invoked on the CodenameOne EDT thread rather than on a separate thread. Notice that the accuracy of this timer is very low! A timer must be linked to a specific form

Constructors

`protected UITimer()`	This constructor is useful when deriving this class to implement a timer.
`public UITimer(Runnable r)`	Constructor that accepts a runnable to invoke on timer elapse

Methods

`public static` `UITimer timer(int timeMillis, boolean repeat, Form parent, Runnable r)`	Convenience method to schedule a UITimer more easily
`public static` `UITimer timer(int timeMillis, boolean repeat, TopLevelContainer parent, Runnable r)`	Schedules a timer bound to any top level, so a component inside a `Window` can have one.
`public static` `UITimer timer(int timeMillis, boolean repeat, Runnable r)`	Convenience method to schedule a UITimer more easily on the current form
`public void schedule(int timeMillis, boolean repeat,` `Form bound)`	Binds the timer to start at the given schedule
`public void schedule(int timeMillis, boolean repeat,` `TopLevelContainer bound)`	Schedules this timer against any top level; see `#timer(int, boolean, TopLevelContainer, Runnable)`.
`public void cancel()`	Stops executing the timer

Constructor details

UITimer

protected UITimer()

This constructor is useful when deriving this class to implement a timer.

UITimer

public UITimer(Runnable r)

Constructor that accepts a runnable to invoke on timer elapse

Parameters

r Runnable: runnable instance

Method details

timer

public static UITimer timer(int timeMillis, boolean repeat, Form parent, Runnable r)

Convenience method to schedule a UITimer more easily

Parameters

timeMillis int: the time from now in milliseconds
repeat boolean: whether the timer repeats
parent Form: the form to which the timer is bound
r Runnable: callback when the timer elapses

Returns

the timer instance

timer

public static UITimer timer(int timeMillis, boolean repeat, TopLevelContainer parent, Runnable r)

Schedules a timer bound to any top level, so a component inside a Window can have one. Component#getComponentForm() is null there, and a port that bound its timer to the form silently ran no timer at all inside a window.

Parameters

timeMillis int: the timer interval in milliseconds
repeat boolean: whether the timer repeats
parent TopLevelContainer: the top level the timer is bound to
r Runnable: the task to run

Returns

the scheduled timer

timer

public static UITimer timer(int timeMillis, boolean repeat, Runnable r)

Convenience method to schedule a UITimer more easily on the current form

Parameters

timeMillis int: the time from now in milliseconds
repeat boolean: whether the timer repeats
r Runnable: callback when the timer elapses

Returns

the timer instance

schedule

public void schedule(int timeMillis, boolean repeat, Form bound)

Binds the timer to start at the given schedule

Parameters

timeMillis int: the time from now in milliseconds
repeat boolean: whether the timer repeats
bound Form: the form to which the timer is bound

schedule

public void schedule(int timeMillis, boolean repeat, TopLevelContainer bound)

Schedules this timer against any top level; see #timer(int, boolean, TopLevelContainer, Runnable).

Parameters

timeMillis int: the timer interval in milliseconds
repeat boolean: whether the timer repeats
bound TopLevelContainer: the top level the timer is bound to

cancel

public void cancel()

Stops executing the timer
