Interface DynamicMetaBean

All Superinterfaces:

MetaBean

public interface DynamicMetaBean
extends MetaBean

A dynamic meta-bean which works with DynamicBean.

A dynamic bean can have properties added or removed at any time. As such, there is a different meta-bean for each dynamic bean. The meta-bean allows meta-properties to be created on demand.
