Yes, my oversight I guess. Probably you'd want to construct an
InputStreamReader. In any case, you can probably pass an InputStream into the
startDocument method from whatever source and then construct the Reader like:
public startDocument (InputStream is) {
InputStreamReader reader = new InputStreamReader (is, charset);
//... continue processsing...
}

In short you cannot find file path fron InputStream, it may be a stream of
bytes from something other than a file.
If you wish to go more specific then FileInputStream has a method for finding
the file descriptor, but then you are tied to files.
Also it is worth noting the javadocs say that FileInputStream is for reading
bytes from a file, if you wish to read characters then use FileReader, see:
http://docs.oracle.com/javase/7/docs/api/java/io/FileInputStream.html
Finally, InputStream is not an interface, it is an abstract class. There are
differences between the two: Abstract classes may have implementation code
where as interfaces are completely abstract, also classes may implement many
interfaces but can only extend a single class (abstract or not). It is
important to understand the differences and why one might use one over the
other. BrailleBlaster probably could do with using a few interfaces.
