Class HtmlTableWalker

java.lang.Object
  ix.iface.util.HtmlTableWalker

Direct Known Subclasses:

ObjectWhiteboard.HtmlAnalyser

public class HtmlTableWalker
extends java.lang.Object

A utility object that can be used to visit the cells of an HTML table. The walker assumes that the HTML document contains a single table and that the table represents something that looks like the properties of a list of objects. The walker requires two collections: rowItems and colItems. The rowItems are the objects whose properties are being shown, and the colItems are the properties. The leftmost column of the table is used to list the objects (rowItems), while the other columns correspond to properties. The top row is headers; then there is a row for each object (each rowItem).

So at the upper left corner is a "th" that describes the objects in some way. Maybe it's just "Objects". The rest of the top row consists of "th" elements that describe the properites, one for each property. Then there is one row for each rowItem. The leftmost item on these rows is a "th" describing the object (rowItem) that corresponds to that row; the rest of the row is "td"s that contain descriptions of that object's property values.

For example:

Block	Size	Colour
A	large	red
B	small	green
C	tiny	blue

A subclass will typically redefine the method walkTD(Element td, Object rowItem, Object colItem).
