const subscription = coreService.on('mySignal').subscribe(data => {
	console.log('Signal received:', data);
});
// To unsubscribe from the signal
subscription.unsubscribe();

off(signal: string): void

Completes the Subject for a specific signal, effectively stopping any future emissions. This also unsubscribes all listeners for the signal.

• Parameters:

  • signal (string): The name of the signal to stop.

• Example:

coreService.off('mySignal');

Example Usage

Here's an example demonstrating how to use the signal management methods in CoreService:

import { CoreService } from 'wacom';
import { Component, OnInit, OnDestroy } from '@angular/core';
import { Subscription } from 'rxjs';
export class AppComponent implements OnInit, OnDestroy {
  private signalSubscription: Subscription;

  constructor(private coreService: CoreService) {}

  ngOnInit() {
    this.setupSignalListeners();
    this.coreService.emit('update', { message: 'Data updated' });
  }

  setupSignalListeners() {
    this.signalSubscription = this.coreService.on('update').subscribe(data => {
      this.handleUpdate(data);
    });
  }

  handleUpdate(data: any) {
    console.log('Update signal received:', data);
  }

  ngOnDestroy() {
    if (this.signalSubscription) {
      this.signalSubscription.unsubscribe();
    }
    this.coreService.off('update');
  }
}

In this example:

1. The on method returns an Observable that emits when the update signal is emitted.
2. The component subscribes to the Observable to handle the emitted data.
3. The emit method is used to emit the update signal with some data.
4. The off method completes the Subject for the update signal, stopping any future emissions and cleaning up the signal.

Await Management

• Example: coreService.complete('myTask');

onComplete(task: string): Promise<void>

Returns a Promise that resolves when the specified task is complete. This is useful for waiting until a task is completed.

• Parameters:

  • task (string): The task to watch for completion, identified by a string.

• Returns:

  • Promise<void>: A Promise that resolves when the task is complete.

• Example: coreService.onComplete('myTask').then(() => { console.log('Task is now complete'); });

completed(task: string): boolean

Checks if a task is completed.

• Parameters:

  • task (string): The task to check, identified by a string.

• Returns:

  • boolean: True if the task is completed, false otherwise.

• Example: if (coreService.completed('myTask')) { console.log('Task is completed'); } else { console.log('Task is not yet completed'); }

Example Usage

Here's an example demonstrating how to use the await management methods in CoreService:

import { CoreService } from 'wacom';
export class AppComponent {
  constructor(private coreService: CoreService) {
    this.checkTaskCompletion();
  }

  async checkTaskCompletion() {
    console.log('Starting task...');

    setTimeout(() => {
      this.coreService.complete('task1');
      console.log('Task completed');
    }, 2000);

    await this.coreService.onComplete('task1');
    console.log('Task is now acknowledged as complete');
  }
}

In this example:

1. The complete method is used to mark a task identified by 'task1' as complete.
2. The onComplete method returns a Promise that resolves when the task is marked as complete, allowing the code to wait until the task is acknowledged as complete.
3. The completed method checks if a task is completed, returning a boolean value.

Locking Management

The CoreService provides methods for managing locks on resources to prevent concurrent access. This is useful in scenarios where you need to ensure that only one part of your application is accessing or modifying a resource at any given time.

• Parameters:

  • which (string): The resource to unlock, identified by a string.

• Example: coreService.unlock('myResource');

onUnlock(which: string): Promise<void>

Returns a Promise that resolves when the specified resource is unlocked. This is useful for waiting until a resource becomes available.

• Parameters:

  • which (string): The resource to watch for unlocking, identified by a string.

• Returns:

  • Promise<void>: A Promise that resolves when the resource is unlocked.

• Example: coreService.onUnlock('myResource').then(() => { console.log('Resource is now unlocked'); });

locked(which: string): boolean

Checks if a resource is currently locked.

• Parameters:

  • which (string): The resource to check, identified by a string.

• Returns:

  • boolean: True if the resource is locked, false otherwise.

• Example: if (coreService.locked('myResource')) { console.log('Resource is currently locked'); } else { console.log('Resource is available'); }

Example Usage

Here's an example demonstrating how to use the locking management methods in CoreService:

import { CoreService } from 'wacom';
export class AppComponent {
  constructor(private coreService: CoreService) {
    this.manageResource();
  }

  async manageResource() {
    this.coreService.lock('resource1');
    console.log('Resource locked');

    setTimeout(() => {
      this.coreService.unlock('resource1');
      console.log('Resource unlocked');
    }, 2000);

    await this.coreService.onUnlock('resource1');
    console.log('Resource is now available for use');
  }
}

In this example:

1. The lock method is used to lock a resource identified by 'resource1'.
2. The unlock method is called after a timeout to unlock the resource.
3. The onUnlock method returns a Promise that resolves when the resource is unlocked, allowing the code to wait until the resource is available again.

This ensures controlled access to the resource, preventing race conditions and ensuring data integrity.
