Package e4s.html Description

The html package contains several basic HTML tags (such as <B>, <BODY>, <CENTER>, ..) which can be assembled one into the other to build up the main HTML output. It also contains elements which are not HTML standard and provide more functionality, such as Trees, Menus, ..

Structure and nesting of HTML output:

The e4s covers most of the HTML tags as classes within this package.

This might be an example for an output you want to create:
The HTML content to be created looks like: 
<HTML>
 <TITLE>e4s Example</TITLE>
 <BODY>
  <TABLE BORDER=1>
        <TR><TD>Hello</TD></TR>
        <TR><TD>World</TD></TR>
  </TABLE>
 </BODY>
</HTML>
The program code to do this output looks like:

The classes provided in this package can be nested, to create an instance of an class within another class, this class provides a function using the name of the class to be instanciated. 

public void HelloWorld( HTML html )
{
        html.setTitle("e4s Example"); 

        TABLE table = html.BODY().TABLE();
        table.setBorder();

        table.TR().TD().print("Hello");
        table.TR().TD().print("World");
}
The structure of the nested objects looks like:
An example can be found in the tutorial: e4s.tutorial.Example_HelloWorld.html.
