Class Inheritance
Imports
java.lang.ref.*, java.lang.reflect.*, java.util.*, java.util.concurrent.*
Helper class used to obtain property descriptors from annotated java beans whose values are set via reflection. This class was implemented to eliminate direct compile-time dependency with java.beans.Introspector and other classes in the java.beans.* package. This is required to allow Android developers to use univocity-parsers. Android developers should add have openbeans-1.0.jar in their classpath to be able to use univocity-parsers. When available, the classes from package com.googlecode.openbeans.* will be used, otherwise the bean introspection classes classes from java.beans.* package will be loaded. If everything fails, then the parser will try to manipulate fields in annotated java beans directly, instead of using their getters and setters.
