Class PseudoClassSelector

java.lang.Object
  jodd.lagarto.csselly.Selector
      jodd.lagarto.csselly.selector.PseudoClassSelector

All Implemented Interfaces:

NodeFilter, NodeListFilter

public class PseudoClassSelector
extends Selector
implements NodeFilter, NodeListFilter

Pseudo class selector. A pseudo-class always consists of a "colon" (:) followed by the name of the pseudo-class and optionally by a value between parentheses.

Selectors introduces the concept of structural pseudo-classes to permit selection based on extra information that lies in the document tree but cannot be represented by other simple selectors or combinators.

Standalone text and other non-element nodes are not counted when calculating the position of an element in the list of children of its parent. When calculating the position of an element in the list of children of its parent, the index numbering starts at 1.
