uk.ac.manchester.cs.BOMSafeJavaCharStream

uk.ac.manchester.cs.owlapi.dlsyntax.parser.JavaCharStream

public class JavaCharStream
extends BOMSafeJavaCharStream

Wrapper for the common JavaCharStream for all parsers. This is needed because we have a request to support UTF-8 files that have an initial BOM. UTF-8 does not need BOMs but some tools insist adding them. Java on the other hand won't support it, and JavaCC does not have an override for this. The result is that the support must be added by hand, and it's easier to have it in one place. This stops JavaCC from rebuilding the wrong files and minimizes duplicated code.
