parseRDFS

public static void parseRDFS(java.lang.String filename)

                             java.io.IOException

Method to parse an RDFS file and load the type information in the RDFS into the engines type sorts. This method parses the file into a XOM tree and passes the XOM Document object to the parseDocument(Document doc) method.

Parameters:

filename - String A string containing the complete path to the RDFS file.

Throws:

nu.xom.ParsingException - Thrown if there is an error in the RDFS file that causes parsing to fail.

nu.xom.ValidityException - Thrown if the XML document is not wellformed or does not conform to the RDFS DTD.

java.io.IOException - Thrown if there is an error reading the file from disk.

parseRDFSString

public static void parseRDFSString(java.lang.String contents)
                            throws ParseException,
                                   nu.xom.ParsingException,
                                   nu.xom.ValidityException,
                                   java.io.IOException

Method that parses an RDFS document contained in a string and load the type information in the RDFS into the engines type sorts. This method parses the string to an XOM document and passes the Document object to the parseDocument(Document doc) method.

Parameters:

contents - String

Throws:

ParseException - Thrown if there is an error in the RDFS document that causes parsing to fail.

nu.xom.ParsingException - Thrown if there is an error parsing at an XML level.
