Class BeanPropertyAccessor<B>

java.lang.Object
  org.cojen.util.BeanPropertyAccessor<B>

public abstract class BeanPropertyAccessor<B>
extends Object

Provides a simple and efficient means of reading and writing bean properties. BeanPropertyAccessor auto-generates code, eliminating the need to invoke methods via reflection. Bean access methods are bound-to directly, using a special hash/switch design pattern.
