Class OboFileParser

java.lang.Object

org.biojava.nbio.ontology.obo.OboFileParser

public class OboFileParser
extends Object

A class to parse the content of an OBO file. It delegates handling of the content to the OBOFileEventListener implementation. This file contains parts of the OBO-Edit file OBOParseEngine, (particularly the encoding and decoding part) http://geneontology.cvs.sourceforge.net/geneontology/go-dev/java/oboedit/sources/org/geneontology/oboedit/dataadapter/OBOParseEngine.java?revision=1.10&view=markup Thanks to the OboEdit developers for giving permission to release this in BioJava.
