Class BeanHelper

java.lang.Object

com.univocity.parsers.common.beans.BeanHelper

public final class BeanHelper
extends java.lang.Object

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 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.
