java.lang.Objectorg.springframework.jmx.export.assembler.AbstractMBeanInfoAssembler
public abstract class AbstractMBeanInfoAssembler
Abstract implementation of the MBeanInfoAssembler interface
that encapsulates the creation of a ModelMBeanInfo instance
but delegates the creation of metadata to subclasses.
This class offers two flavors of Class extraction from a managed bean
instance: getTargetClass(java.lang.Object), extracting the target class behind
any kind of AOP proxy, and getClassToExpose(java.lang.Object), returning the
class or interface that will be searched for annotations and exposed
to the JMX runtime.
