public class DocInstance
extends java.lang.Object

DocInstance - call different document processing routines. They are grouped in two classes - RDFInstance and HTMLInstance. The goal or these manipulations is to obtain three things:

build RDF models from one or more fragments of RDF found within the document
extract the list of namespaces used within RDF
extract the list of URI references from both RDF and HTML parts of the document

Constructor Summary
`DocInstance(Cache cache, java.lang.String uristring, java.lang.String parentstring)` Constructor: initialize data structures, but dont assign current and parent URI, as they cause exceptions

Method Summary
`void`	`analyzeHTML()` Analyze the HTML text and find out the outgoing URLs
`void`	`analyzeRDF()` Analyze the RDF text and find out uris, namespaces and rdflists
`static java.lang.String`	`encode(java.lang.String val)` This method is adapted from org.gjt.vinny.html.HTMLEncoder, it is a utility method for converting a string into a format suitable for placing inside HTML, so that special symbols: <,>,&," and ' are properly escaped.
`java.util.Vector`	`getNs()`
`java.util.Vector`	`getRdf()`
`java.util.Vector`	`getUri()`
`static void`	`main(java.lang.String[] args)` for debugging
