C# 클래스 GSF.Threading.SynchronizedOperationBase

Base class for operations that cannot run while they is already in progress.

This class handles the synchronization between the methods defined in the ISynchronizedOperation interface. Implementers should only need to implement the ExecuteActionAsync method to provide a mechanism for executing the action on a separate thread.

공개 메소드들

메소드	설명
Run ( ) : void	Executes the action on this thread or marks the operation as pending if the operation is already running. When the operation is marked as pending, it will run again after the operation that is currently running has completed. This is useful if an update has invalidated the operation that is currently running and will therefore need to be run again. This method does not guarantee that control will be returned to the thread that called it. If other threads continuously mark the operation as pending, this thread will continue to run the operation indefinitely.
RunOnce ( ) : void	Executes the action on this thread or marks the operation as pending if the operation is already running. When the operation is marked as pending, it will run again after the operation that is currently running has completed. This is useful if an update has invalidated the operation that is currently running and will therefore need to be run again.
RunOnceAsync ( ) : void	Executes the action on another thread or marks the operation as pending if the operation is already running. When the operation is marked as pending, it will run again after the operation that is currently running has completed. This is useful if an update has invalidated the operation that is currently running and will therefore need to be run again.
TryRun ( ) : void	Attempts to execute the action on this thread. Does nothing if the operation is already running. This method does not guarantee that control will be returned to the thread that called it. If other threads continuously mark the operation as pending, this thread will continue to run the operation indefinitely.
TryRunOnce ( ) : void	Attempts to execute the action on this thread. Does nothing if the operation is already running.
TryRunOnceAsync ( ) : void	Attempts to execute the action on another thread. Does nothing if the operation is already running.

메소드	설명
ExecuteAction ( ) : bool	Executes the action once on the current thread.
ExecuteActionAsync ( ) : void	Executes the action on a separate thread. Implementers should call ExecuteAction on a separate thread and check the return value. If it returns true, that means it needs to run again. The following is a sample implementation using a regular dedicated thread. `protected override void ExecuteActionAsync() { Thread actionThread = new Thread(() => { while (ExecuteAction()) { } }); actionThread.Start(); }`
SynchronizedOperationBase ( System.Action action ) : System	Creates a new instance of the SynchronizedOperationBase class.
SynchronizedOperationBase ( System.Action action, Action exceptionAction ) : System	Creates a new instance of the SynchronizedOperationBase class.

ExecuteAction() 보호된 메소드

Executes the action once on the current thread.

ExecuteActionAsync() 보호된 추상적인 메소드

Executes the action on a separate thread.

Implementers should call ExecuteAction on a separate thread and check the return value. If it returns true, that means it needs to run again. The following is a sample implementation using a regular dedicated thread.

 protected override void ExecuteActionAsync() { Thread actionThread = new Thread(() => { while (ExecuteAction()) { } }); actionThread.Start(); }

리턴	void

Run() 공개 메소드

Executes the action on this thread or marks the operation as pending if the operation is already running.

When the operation is marked as pending, it will run again after the operation that is currently running has completed. This is useful if an update has invalidated the operation that is currently running and will therefore need to be run again.

This method does not guarantee that control will be returned to the thread that called it. If other threads continuously mark the operation as pending, this thread will continue to run the operation indefinitely.
