Class DeferredDocumentImpl

All Implemented Interfaces:
Serializable, Cloneable, DeferredNode, Document, DocumentEvent, EventTarget, Node, NodeList, DocumentRange, DocumentTraversal

public class DeferredDocumentImpl extends DocumentImpl implements DeferredNode
The Document interface represents the entire HTML or XML document. Conceptually, it is the root of the document tree, and provides the primary access to the document's data.

Since elements, text nodes, comments, processing instructions, etc. cannot exist outside the context of a Document, the Document interface also contains the factory methods needed to create these objects. The Node objects created have a ownerDocument attribute which associates them with the Document within whose context they were created.

INTERNAL:

Usage of this class is not supported. It may be altered or removed at any time.

    • binarySearch

      protected static int binarySearch(int[] values, int start, int end, int target)
      Performs a binary search for a target value in an array of values. The array of values must be in ascending sorted order before calling this method and all array values must be non-negative.
