Typescript dynamic class methods -

problem

how can 1 add type checking dynamically created class method?

example

given simple property class.

class property {   value: any;   name: string;    constructor(name: string, value: any) {     this.name = name;     this.value = value   } } 

and entity class

class entity {   name: string;   properties: property[];     constructor(name: string, properties: property[]) {     this.name = name;     this.properties = properties;      this.properties.foreach((p: property, index: number) => {       this[p.name] = (value: string): => {         if (value) {           this.properties[index].value = value;         }         return this.properties[index].value;       }     }, this);   } } 

important part: this[p.name] = function ... (we don't know name of method @ "transpile" time).

we following error when transpiling javascript:

var car = new domain.entity(   'car',   [     new domain.property('manufacturer', 'ford'),     new domain.property('model', 'focus')   ] );  car.model() // error ts2339: property 'model' not exist on type 'entity'. 

i know uncommon use of classes different instances of entity have different methods defined. there way rid of error, i.e. typescript able identify proper interface per instance, or @ least silent error?

notes

this valid javascript , 1 use in following manner:

var car = new domain.entity(   'car',   [     new domain.property('manufacturer', 'ford'),     new domain.property('model', 'focus')   ] );  car.model()          // 'focus' car.model('transit') // 'transit' 

i'm aware has been asked on similar question, case different method name defined @ runtime.

if have dynamic properties want access use any type bypass type checks variable. can either declare variable any type go, or use type assertion operator (as) @ later point. here possible variants:

var car: = new domain.entity(...); car.model();  var car = new domain.entity(...) any; car.model();  var car = new domain.entity(...); (car any).model();
