Interface HTMLDocument

All Superinterfaces:
  Document, Node

public interface HTMLDocument
extends Document

An `HTMLDocument` is the root of the HTML hierarchy andholds the entire content. Beside providing access to the hierarchy, italso provides some convenience methods for accessing certain sets ofinformation from the document.

The following properties have been deprecated in favor of the corresponding ones for the BODY element:alinkColorbackgroundbgColorfgColor linkColorvlinkColor

Method Detail

### getTitle

    public java.lang.String getTitle()

  The title of a document as specified by the `TITLE`element in the head of the document.
