ParentElementClass

Definition

Namespace: DOM.Abstracts
Assembly: DOM.dll

Parent element that can contain child elements and provides child management helpers.

Remarks

is the base class for every DOM element that can contain other elements (sections, paragraphs, tables, headers/footers, etc.). It manages an ordered collection, keeps each child's parent reference up to date, and provides insert / remove / query helpers. ParentElement Children Most user-facing container APIs (,,, and so on) are implemented in the subclass, but they all build on the primitive operations provided here.
