Methods

addEntity

getEntity

getEntityDecorator

  • getEntityDecorator(): ClassDecorator
  • Returns a class decorator which can be used to decorate classes as entities.

    Returns ClassDecorator

hasEntity

  • hasEntity(name: Name): boolean
  • Checks whether the schema has an entity with the given name.

    Parameters

    Returns boolean

initialize

  • initialize<T>(props?: Partial<T>): void
  • This method applies its 1st argument (if any) to the current instance using Object.assign().

    Supposed to be overridden in the subclasses to customize the instance creation process.

    Type parameters

    Parameters

    • Optional props: Partial<T>

    Returns void

Static new

  • new<T>(this: T, props?: Partial<InstanceType<T>>): InstanceType<T>
  • This is a type-safe static constructor method, accepting a single argument, with the object, corresponding to the class properties. It will generate a compilation error, if unknown property is provided.

    For example:

    class MyClass extends Base {
        prop     : string
    }
    
    const instance : MyClass = MyClass.new({ prop : 'prop', wrong : 11 })

    will produce:

    TS2345: Argument of type '{ prop: string; wrong: number; }' is not assignable to parameter of type 'Partial<MyClass>'.
    Object literal may only specify known properties, and 'wrong' does not exist in type 'Partial<MyClass>'

    The only thing this constructor does is create an instance and call the initialize method on it, forwarding the first argument. The customization of instance is supposed to be performed in that method.

    Type parameters

    Parameters

    • this: T
    • Optional props: Partial<InstanceType<T>>

    Returns InstanceType<T>
