# geometryEditor.model.ChildLinearRing

{% note info %}

The constructor of the geometryEditor.model.ChildLinearRing class is hidden, as this class is not intended for autonomous initialization.

{% endnote %}

Extends [geometryEditor.model.ChildLineString](https://yandex.com/dev/jsapi-v2-1/doc/en/v2-1/ref/reference/geometryEditor.model.ChildLineString.md).

Model for a child closed contour. The constructor is not available in the package.full (a standard set of modules). This module is loaded on demand.
