Class BeanConverter

java.lang.Object
  gov.nasa.arc.brahms.vm.api.convert.BeanConverter

All Implemented Interfaces:

IConverter

public class BeanConverter
extends java.lang.Object
implements IConverter

BeanConverter handles the conversion between Java and Brahms objects with the Java objects complying with the Java Bean specification for automatic discovery of members and their read/write methods. It assumes that a Brahms class with the same qualified name as the Java class exists and that the Brahms attribute and relation names are the same as the bean property names of the Java class.
