com.sun.xml.bind.v2.runtime.reflect.Accessor
Accesses a particular property of a bean.

This interface encapsulates the access to the actual data store. The intention is to generate implementations for a particular bean and a property to improve the performance.

Accessor can be used as a receiver. Upon receiving an object it sets that to the field. @author Kohsuke Kawaguchi (kk@kohsuke.org) @see Accessor.FieldReflection @see TransducedAccessor
