Class MetaBean<T>

java.lang.Object

org.apache.activemq.artemis.utils.bean.MetaBean<T>

public class MetaBean<T>
extends Object

Receives a metadata about a class with methods to read, write and certain gates. And provides a generic logic to convert to and from JSON.

As a historical context the first try to make a few objects more dynamic (e.g. AddressSettings) was around BeanUtils however there was some implicit logic on when certain settings were Null or default values. for that reason I decided for a meta-data approach where extra semantic could be applied for each individual attributes rather than a generic BeanUtils parser.
