Class Generation

Class generation is similar to JAXB and Zeus. Castor supports XML Schema instead of DTDs (DTDs are not supported by Castor). Sabawoon Education Academy Date 19.8.2017 Class: 2nd Maths: Revision :

Unmarshalling and marshalling

Unmarshalling and marshalling are dealt with marshall() and unmarshall() methods respectively. During marshalling, conversion process from Java to XML is carried out, and, during unmarshalling, conversion process from XML to Java is carried out. Mapping files are the equivalent of a binding schema, which allows to transforms names from XML to Java and vice versa.
