ROIT model mapper makes it easy to convert any object or JSON to the model

const jsonMetadataKey = "jsonProperty";
export function JsonProperty<T>(metadata?: IJsonMetaData<T> | string): any {
    if (metadata instanceof String || typeof metadata === "string") {
        return Reflect.metadata(jsonMetadataKey, {
            name: metadata,
            clazz: undefined,
            linear: false
        });
    } else {
        let metadataObj = <IJsonMetaData<T>>metadata;
        return Reflect.metadata(jsonMetadataKey, {
            name: metadataObj ? metadataObj.name : undefined,
            clazz: metadataObj ? metadataObj.clazz : undefined,
            linear: metadataObj ? metadataObj.linear : false,
            alwaysArray: metadataObj ? metadataObj.alwaysArray : false
        });
    }
}

export interface IJsonMetaData<T> {
    name?: string,
