The MBeanAttribute object associating to the object identifier.

Throws:

SnmpException - Thrown when any error occurs.

setAttrByName

protected MBeanAttribute setAttrByName(java.lang.String name,
                                       MBeanAttribute attr)
                                throws SnmpException

Sets the MBeanAttribute object that matches to the attribute name in the MBean.

setAttrByName in class MBeanMeta

Parameters:

name - The name of the attribute.

attr - The MBeanAttribute object that contains the data to set into the MBean object.
