constructor

+ new CompleteTask(props: ConstructorType‹CompleteTask› & object): CompleteTask

Inherited from CreateEmployee.constructor

Overrides void

Creates an instance of Message.

Parameters:

Name	Type	Description
`props`	ConstructorType‹CompleteTask› & object	Properties matching generic `T` with `targetId` as `Guid

Returns: CompleteTask

Properties

id

• id: Guid

`Optional` metadata

• metadata? : Record‹string, any›

Inherited from CreateEmployee.metadata

remarks Since Command & Event are frozen after construction, metadata property must be assigning on construction. This ensures that content of message is immutable; however metadata as an object will be unaffected by Object.freeze - thus allowing for additional data to be assigned later on. Exposed as optional - but always assigned with use of Message.prototype.processProps for easier interaction.

`Optional` schemaVersion

• schemaVersion? : number

Inherited from CreateEmployee.schemaVersion

Overrides void

targetId

• targetId: Guid | string

Inherited from CreateEmployee.targetId

`Optional` timestamp

• timestamp? : Date

Inherited from CreateEmployee.timestamp

remarks Exposed as optional - but always assigned with use of Message.prototype.processProps for easier interaction.

Methods

###  toPlainObject

▸ **toPlainObject**(): *[Props](../modules/types.md#props)*

*Inherited from [CreateEmployee](createemployee.md).[toPlainObject](createemployee.md#toplainobject)*

Converts properties to plain object.

**`remarks`** 
**Loosing object references is required** since in scenarios when properties resolved
from `toPlainObject` are transformed - in such changes to the modified plain object
will cascade to original instance(**THIS** instance, since properties are **referenced**).

**`example`** 
```ts
@define()
class Point extends DefinableMixin {
  x: number;
  y: number;
  z: number;
}

const point = new Point({x: 1, y: 2, z: 3})

typeName

▸ typeName(): TypeName

validateProps

▸ validateProps(props: Props, propTypes: PropTypes, isStrict: boolean): boolean

Inherited from CreateEmployee.validateProps

Validates if provided properties matches prop types.

throws {ValidationError} Thrown if the passed properties do not match prop types.

remarks Disabling of runtime validation is possible via Kernel's configuration(and by that env flags also) or by annotating class with @validable(false).

This is useful when there is external layer(like transportation) that does all the heavy lifting of validation and there are no other sources of incoming data beside points that is handled by layer.

Use env EVEBLE_VALIDATION_TYPE set to manual to disable validation on initialization. You ca re-enable it again on your application configuration via path validation.type set to runtime before staring application.

example

@define()
class MyClass extends DefinableMixin {
  stringKey: string

  constructor(props: Record<keyof any, any>) {
    super()
    Object.assign(this, props);
  }
}

const instance = new MyClass({stringKey: 'my-string'});
expect(
  () => instance.validateProps({stringKey: 1337}, this.getPropTypes())
).to.throw(ValidationError)

Parameters:

Name	Type	Default	Description
`props`	Props	{}	Properties to validate.
`propTypes`	PropTypes	-	Properties types.
`isStrict`	boolean	true	Flag indicating that validation should be done in strict mode.

remarks Since using mixins with polytype on extendable classes like: Serializable, Entity, EventSourceable, ValueObject will result in loosing all registered hooks on metadata

this ensures that hook can be easily re-applied.

Returns: void

`Static` from

▸ from(...sources: Record‹string, any›[]): any

Inherited from CreateEmployee.from

};
const props3 = {
  hobby: 'martial arts',
};
const person = Person.from(props1, props2, props3);
expect(person).to.be.instanceof(Person);
expect(person).to.be.eql({
  firstName: 'Jane',
