Element

class Element(val tag: String, var attrs: Map<String, String>, val children: MutableList<KiteXmlNode> = ArrayList()) : KiteXmlNode(source)

Constructors

Element

constructor(tag: String, attrs: Map<String, String>, children: MutableList<KiteXmlNode> = ArrayList())

Properties

attrs

var attrs: Map<String, String>

The attributes, by name. A script layer replaces the map when a script sets or removes one, on a tree of its own that no layout reads meanwhile (#41).

children

val children: MutableList<KiteXmlNode>

parent

var parent: KiteXmlNode.Element?

Enclosing element, set by the tree builder when the child is appended, and null at the root. CSS selector matching needs it for sibling combinators and the child-indexed pseudo-classes.

tag

val tag: String

Functions

indexInParent

fun indexInParent(): Int

This element's index in its parent's children, or -1 when it has none or is not among them. The answer is remembered and checked on the next call, so a selector's sibling step costs O(1) where a scan of the parent from its first child cost the element's position, and h1 ~ p over n siblings cost n^3/6 (#990). A tree that changed since is scanned again.
