Class ExpiringSwingTimer

java.lang.Object

generic.timer.GhidraSwingTimer

generic.timer.ExpiringSwingTimer

All Implemented Interfaces:

GhidraTimer, ActionListener, EventListener

public class ExpiringSwingTimer
extends GhidraSwingTimer

This class allows clients to run swing action at some point in the future, when the given condition is met, allowing for the task to timeout. While this class implements the GhidraTimer interface, it is really meant to be used to execute a code snippet one time at some point in the future.

Both the call to check for readiness and the actual client code will be run on the Swing thread.

Constructor Details

ExpiringSwingTimer

public ExpiringSwingTimer(int delay,
 int expireMs,
 BooleanSupplier isReady,
 Runnable runnable)

Constructor

Note: this class sets the parent's initial delay to 0. This is to allow the client code to be executed without delay when the ready condition is true.

Parameters:

delay - the delay between calls to check isReady

expireMs - the amount of time past which the code will not be run

isReady - true if the code should be run

runnable - the code to run

Method Details

runWhen

public static ExpiringSwingTimer runWhen(BooleanSupplier isReady,
 int expireMs,
 Runnable runnable)

Runs the given client runnable when the given condition returns true. The returned timer will be running.

Once the timer has performed the work, any calls to start the returned timer will not perform any work. You can check didRun() to see if the work has been completed.

Parameters:

isReady - true if the code should be run

expireMs - the amount of time past which the code will not be run

runnable - the code to run

Returns:

the timer object that is running, which will execute the given code when ready

get

public static <T> ExpiringSwingTimer get(Supplier<T> supplier,
 int expireMs,
 Consumer<T> consumer)

Calls the given consumer with the non-null value returned from the given supplier. The returned timer will be running.

Once the timer has performed the work, any calls to start the returned timer will not perform any work. You can check didRun() to see if the work has been completed.

Type Parameters:

T - the type used by the supplier and consumer

Parameters:

supplier - the supplier of the desired value

expireMs - the amount of time past which the code will not be run

consumer - the consumer to be called with the supplier's value

Returns:

the timer object that is running, which will execute the given code when ready

didRun

public boolean didRun()

Returns true if the client runnable was run

Returns:

true if the client runnable was run

Specified by:

start in interface GhidraTimer

Overrides:

stop

public void stop()

Specified by:

stop in interface GhidraTimer

Overrides:

isExpired

public boolean isExpired()

Returns true the initial expiration period has passed

Returns:

true if expired

setTimerCallback

public void setTimerCallback(TimerCallback callback)

Specified by:

setTimerCallback in interface GhidraTimer

Overrides:

setTimerCallback in class GhidraSwingTimer
