Node class abstract

An abstract node in a document tree.

Represents a segment of a Notus document with specified offset and length.

The offset property is relative to parent. See also documentOffset which provides absolute offset of this node within the document.

The current parent node is exposed by the parent property. A node is considered mounted when the parent property is not null.
