Interface IConfigurable

It can be added to any existing class by implementing a single configure() method.

If you need to emphasis the fact that configure() method can be called multiple times to change object configuration in runtime, use IReconfigurable interface instead.

ConfigParams

Example

export class MyClass implements IConfigurable {
    private _myParam: string = "default value";

    public configure(config: ConfigParams): void  {
        this._myParam = config.getAsStringWithDefault("options.param", myParam);
        ...
    }
}
