Examples of javax.xml.bind.Unmarshaller.unmarshal()

javax.xml.bind.Unmarshaller.unmarshal()

This method takes opens the given file pFile for input. The Unmarshaller reads the byte stream contained in the file and converts it into an equivalent JAXB object.
@param pFile The file being read. @return The JAXB object read from the file. @throws JAXBException An unexpected problem (for example anIOException) occurred. @throws UnmarshalException The JAXB object is invalid or couldnot be read from the byte stream for similar reasons. @throws IllegalArgumentException The parameter was null.
