Deprecated. use the Java class java.util.Timer

@Deprecated
public class WOTimer
extends Object

WOTimer creates timer objects, or more simply, timers. A timer waits until its fireDate is reached and then fires, sending a specified message to a specified object. If you specify that the timer should repeat, it automatically reschedules itself after it fires.

The static method scheduledTimer creates and schedules a timer. The constructors create timers which can later be scheduled by invoking the method schedule. Timers can be unscheduled by invoking invalidate on the timer to be unscheduled.

Constructor Summary

WOTimer(long ti, Object aTarget, String aSelectorName, Object userInfo, Class userInfoClass, boolean repeats)

WOTimer(NSTimestamp fireDate, long interval, Object aTarget, String aSelectorName, Object userInfo, Class userInfoClass, boolean repeats)

NSTimestamp	fireDate() Deprecated. Return the NSTimestamp at which the WOTimer will first fire.
int	hashCode() Deprecated.
void	invalidate() Deprecated. Unschedules the timer and marks it as invalid.
boolean	isValid() Deprecated. Returns whether or not the timer is valid.
void	schedule() Deprecated. Schedule the WOTimer to be fired.
static WOTimer	scheduledTimer(long ti, Object aTarget, String aSelectorName, Object userInfo, boolean repeats) Deprecated. Creates a timer which will fire after ti milliseconds, and at intervals ti thereafter (if repeats is true).

Constructor Detail

WOTimer

public WOTimer(long ti,
               Object aTarget,
               String aSelectorName,
               Object userInfo,
               Class userInfoClass,
               boolean repeats)

Deprecated.

Creates a timer which will fire after ti milliseconds, and at intervals ti thereafter (if repeats is true).

If userInfoClass is null, aSelectorName must take an object of class WOTimer as a parameter, and userInfo will be available to the selector invoking userInfo on the parameter timer. Otherwise, aSelectorName must take an object of class userInfoClass and userInfo must be an object of this class.

Parameters:

ti - the interval in milliseconds between successive firings of the timer

aTarget - the method on which aSelectorName will be invoked

aSelectorName - the method to be invoked when the timer fires

userInfo - user information that should be passed on when the timer fires

userInfoClass - the class of userInfo

repeats - whether or not the timer should fire repeatedly

WOTimer.WOTimer(NSTimestamp fireDate, long ti, Object aTarget, String aSelectorName, Object userInfo, Class userInfoClass, boolean repeats)

WOTimer

public WOTimer(NSTimestamp fireDate,
               long interval,
               Object aTarget,
               String aSelectorName,
               Object userInfo,
               Class userInfoClass,
               boolean repeats)

Deprecated.

Creates a timer which will fire at fireDate, and at intervals ti thereafter (if repeats is true).

If userInfoClass is null, aSelectorName must take an object of class WOTimer as a parameter, and userInfo will be available to the selector invoking userInfo on the parameter timer. Otherwise, aSelectorName must take an object of class userInfoClass and userInfo must be an object of this class.

Parameters:

fireDate - the time at which the timer should first fire

interval - the interval in milliseconds between successive firings of the timer

aTarget - the method on which aSelectorName will be invoked

aSelectorName - the method to be invoked when the timer fires

userInfo - user information that should be passed on when the timer fires

userInfoClass - the class of userInfo

repeats - whether or not the timer should fire repeatedly

                                     boolean repeats)

Deprecated.

Creates a timer which will fire after ti milliseconds, and at intervals ti thereafter (if repeats is true).

aSelectorName must take an object of class WOTimer as a parameter, and userInfo will be available to the selector invoking userInfo on the parameter timer.
