Typed setters for the entities about snakeyaml HOT 3 CLOSED

Question: 
SnakeYAML does not work properly with the above class.
This is because setter returns an object instead of void.
==============================
Answer: 
this is not a SnakeYAML issue. This class violates the JavaBean spec.
I can imagine this was possibly desired by someone to implement a "chaining" 
style of 
coding, but this is no longer a correct JavaBean. The JavaBean spec requires 
that the 
return type of set* functions be 'void', and various tools and frameworks 
enforce 
this requirement. (XmlEncoder for instance)
If a chaining-style setter is desired, I'd recommend making this a separate 
method on 
the bean rather than replacing the standard setter.

py4fun is correct and naming things in a way spec says gives you (almost) what 
you want  out of the box.
But if you still need this one to work you may try to create corresponding 
BeanInfo class and provide correct 
PropertyDescriptor for the id giving setId as a setter name.

so it will be EntityBeanInfo in the same package as Entity or you have to set 
up Introspector BeanInfo paths and 
so on. 

(consult JavaBeans spec. 8 Introspection)

It is also possible to provide your own Constructor and Representer to work 
with the
Entity class.
