Configurator

private Configurator(java.lang.String configFile)
              throws SnmpException

Constructs the Configurator with the passed config file name.

Parameters:

configFile - Config file name

Throws:

SnmpException - thrown if any error occurs during the object instantiation.

Method Detail

put

public java.lang.Object put(java.lang.Object key,
                            java.lang.Object value)

When the key is "MBEAN_CLASS_NAME", we simply add it to the MBean class list. Otherwise, we still map the value using the defult put method in the super class.

Specified by:

put in interface java.util.Map

Overrides:

put in class java.util.Hashtable

Parameters:

key - The key mapping to the value

value - The value matched to the key

When the key is "MBEAN_CLASS_NAME", we simply get it from MBean class list. Otherwise, we get the value by calling the default getProperty method in the super calss.

Overrides:

getProperty in class java.util.Properties

getMBeanClassNameList

public java.lang.String[] getMBeanClassNameList()

Gets the list of MBean class names.

Returns:

arrayClassNames List of MBean class name.

create

public static Configurator create(java.lang.String configFile)
                           throws SnmpException

Parameters:

configFile - Config file name

Returns:

Singleton object of the Configurator.
