All Implemented Interfaces:
Field, FieldChain, Member
Direct Known Subclasses:
IndirectField, ManageableType.Field
public abstract class PersistenceField extends MemberBase implements Field, FieldChain
A PersistenceField represents a field which can be handled by classes of the persistence package. It is an abstract base class; its methods imply that a PersistenceField is composed of a chain of fields of class ManageableType.Field. E.g., if an object has a field location of type javax.vecmath.Point3f, such a chain could be (location, x) (then it denotes the x field of the location field of the object). A chain may involve array components. An array component is either an array component in the sense of the Java programming language, e.g., object.values[i], or an element of java.util.List or one of the primitive list classes in de.grogra.util, e.g., object.values.get (i). When a PersistenceField containing array components is accessed by one of its methods, the indices parameter has to provide one index for every component. E.g., a field access object.values[i].locations[j].x is represented by the chain (values, [], locations, [], x), where [] represents array components, and indices = {i, j}.
