ElementClass

Definition

Namespace: DOM.Abstracts
Assembly: DOM.dll

Base DOM element implementation that participates in the parent/child tree.

extends with the positional and parent-link behaviour required by elements that are placed inside a container: an index within the parent's children, a back-reference to the parent, and the insert / remove / replace operations that act on the parent's collection. Element BaseElement Most user-facing elements (paragraphs, tables, images) derive from which itself derives from this class. Elements that need to live in a container but do not contain children of their own can derive directly from . ParentElement Element
