CommonErrors.prototype.delete()
Deletes the error of a specified id
from the object.
public delete<ErrorId extends Id>(id: ErrorId): this {
this.#errors.delete(id);
return this;
}
Generic type variables
A generic type variable ErrorId
constrained by the generic type variable Id
of the CommonErrors
object indicates the type picked from the Id
and its exact type is useful in picking the specific error from the storage.
Parameters
The unique identification of a generic type variable ErrorId
to remove the error from the object.
Return type
this
this
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;
