org.apache.bcel.generic.FieldGen
Template class for building up a field. The only extraordinary thing one can do is to add a constant value attribute to a field (which must of course be compatible with to the declared type). @version $Id: FieldGen.java,v 1.1.1.1 2001/10/29 20:00:12 jvanzyl Exp $ @author M. Dahm @see Field
