This class defines all valid FormatTypes.
We start by defining a series of basic interfaces to define all known format types and specify how they relate to one another. Please note that these are hierarchical in nature. Strongly typed FormatType interfaces include:
ft = FormatType.HTML_4_0
Note here that we assigned the format type value by referring to a concrete instance of the format type (the idea here is that if you wish to assign a FormatType to some object you must select a concrete type).
Concrete format types include:
Now lets say we want to check if 'ft' is at least compatible with HTML 3.2, we can use the instanceOf() operator like this:
if (ft instanceof FormatType.Html3x) {...}
Since FormatType.HTML_4_0 implements FormatType.Html3x the logic check succeeds and our 'if' statement is executed.
In case you are wondering 'Why in the world did we go to the effort to define all these interfaces and such' the reason is that we wanted to make it easy to check for "classes" of formats (ie. anything that conforms to HTML 3.2 for instance...an HTML 4.0 browser does). The net effect of this is that you can write code that targets a baseline and as new versions come out your code will continue to work.
The reason we used interfaces is that as code evolves it sometimes supports more than one format. XHTML is an excellent example of this. There are 2 different flavors of this: XHTML Basic is a subset of XHTML. What this means is that XHTML_1_x should be an instance of XHTML_Basic. However, it should also be an instance of XHTML_Basic_1_x. Since Java does not allow multiple inheritance in concrete classes, we had to instead use interfaces so that a given format can specify support multiple formats.
