                 javax.management.MBeanNotificationInfo[] notifications)

Parameters:

className - The name of the Java class of the MBean

description - A human readable description of the MBean (optional).

attributes - The list of exposed attributes of the MBean.

constructors - The list of public constructors of the MBean.

operations - The list of operations of the MBean.

notifications - The list of notifications emitted.

setMBeanInfo

protected void setMBeanInfo(javax.management.MBeanInfo info)

Parameters:

info - The MBeanInfo to be set.

getAttributes

public javax.management.AttributeList getAttributes(java.lang.String[] attributes)

Specified by:

getAttributes in interface javax.management.DynamicMBean

setAttributes

public javax.management.AttributeList setAttributes(javax.management.AttributeList attributes)
