TCThread - sigma-rt

new TCThread(name, func, onErroropt)

One‑shot task executed on the shared cached thread pool. Supports cooperative
pause/resume/stop and exposes liveness/interruption flags for predictable coordination.

Examples

// Example: basic usage
var t = new TCThread("job1", () => delay(100));
t.start();
print(TCWait(t, 1000));

// Example: cooperative pause/resume
var t2 = new TCThread("pausable", (self) => {
    for (var i=0;i<3;i++){
        delay(60);
        if (self.isPaused()) while (self.isPaused()) delay(40);
    }
});
t2.start(t2);
t2.pause();
delay(150);
t2.resume();
print(TCWait(t2, 1000));

Parameters:

Name	Type	Attributes	Description
`name`	string		Logical name used in registries and for TCWait by name.
`func`	function		User function executed when the thread starts. Arguments passed to TCThread#start are forwarded to this function.
`onError`	function	<optional>	Optional non‑fatal error handler.

Methods

getFunctionName() → {string}

Example

var t=new TCThread("p",()=>delay(500));
t.start();
print(t.getFunctionName());

Returns:

Logical name.

Type: string

getJavaThread() → {java.lang.Thread|null}

Example

var t=new TCThread("p",()=>delay(500));
t.start();
var jt=t.getJavaThread();

Returns:

Underlying Java thread.

Type: Thread | null

isAlive() → {boolean}

Check liveness (includes short "starting" window).

Example

var t=new TCThread("p",()=>delay(500));
t.start();
print(t.isAlive());

Returns:

Type: boolean

isPaused() → {boolean}

Example

var t=new TCThread("p",()=>delay(500));
t.start();
print(t.isPaused());

Returns:

Whether the thread is paused.

Type: boolean

isRunning() → {boolean}

Example

var t=new TCThread("p",()=>delay(500));
t.start();
print(t.isRunning());

Returns:

Whether the thread is still running.

Type: boolean

isVirtual() → {false}

Example

var t=new TCThread("p",()=>delay(500));
t.start();
print(t.isVirtual()); // false

Returns:

Distinguish from virtual threads.

Type: false

join()

Blocking join; prefer TCWait with timeout.

Example

var t=new TCThread("p",()=>delay(500));
t.start();
t.join();

pause()

Request cooperative pause.

Example

var t=new TCThread("p",()=>delay(500));
t.start();
t.pause();

resume()

Resume after a cooperative pause.

Example

var t=new TCThread("p",()=>delay(500));
t.start();
t.resume();

start()

Start execution exactly once. Additional calls are ignored.
Arguments are forwarded to the user function.

Example

// Example: start twice (second call is ignored)
var t = new TCThread("once", () => delay(10));
t.start();

stop()

Signal the thread to stop and attempt to interrupt/cancel underlying Java thread.

Example

// Example: stop a long task early
var t = new TCThread("willStop", () => delay(2000));
t.start();
delay(100);
t.stop();
print(TCWait(t, 300)); // usually false

wasInterrupted() → {boolean}

Example

var t=new TCThread("p",()=>delay(500));
t.start();
print(t.wasInterrupted());

Returns:

True if interrupted path observed.

Type: boolean
