      • getConfigDataId

        public static ConfigDataId getConfigDataId(javax.management.AttributeList attrList)
        Assign the config data id for the specified attribute list. If the config id attribute exist already then just return the config data id, otherwise this method assign a local ref id.

        Set the attribute value for the specified attribute. If the attribute exists, then this method overwrites the attribute value, otherwise it add the attribute to the attribute list.
        Parameters:
        attrList - the attribute list.
        name - the name of attribute.
        value - the value of the attribute.
