Example usage

// Example usage.
import { CommonErrors } from '@angular-package/error';

// Define new `TestClass` to add error to the map storage.
export class TestClass<Id extends string> extends CommonErrors<Id> {
  public get errors(): Map<Id, any> {
    return super.errors;
  }
  public set<ErrorId extends Id>(
    problem: string,
    fix: string,
    id: ErrorId
  ): this {
    this.errors.set(id, new Error(problem, fix, id));
    return this;
  }
}

// Initialize the `TestClass`.
const generalErrors = new TestClass('EG: 4332', 'EG: 4331', 'EG: 4330');

// Set the errors.
generalErrors
  .set(
    'Bad parameter type, detected number',
    'Provide proper type, the `string`',
    'EG: 4330'
  )
  .set('Detected numbers', 'Provide only letters', 'EG: 4331');

// Returns Map(2)
generalErrors.errors;

// Deletes the error of the `EG: 4330` identification number.
generalErrors.delete('EG: 4330');

// Returns Map(1)
generalErrors.errors;
