Class MOServerPersistence

java.lang.Object

org.snmp4j.agent.io.MOServerPersistence

public class MOServerPersistence
extends Object

The MOServerPersistence provides persistence operations to load and save serialized MIB data. SerializableManagedObjects that are SerializableManagedObject.isVolatile() are not loaded and saved

Modifier and Type	Method	Description
void	loadData(MOInput input)
void	loadData(MOInput input, boolean configureOnly)	Load the persistent data into all SerializableManagedObjects that are available in the MOServer provided during construction and that are not SerializableManagedObject.isVolatile().
void	saveData(MOOutput output)	Saves the serializable data of the associated servers to the given MOOutput.
void	saveData(MOOutput output, MOPriorityProvider priorityProvider)	Saves the serializable data of the associated servers to the given MOOutput in the order defined by MOPriorityProvider.

Method Details

loadData

public void loadData(MOInput input)
              throws IOException

Throws:

IOException

loadData

public void loadData(MOInput input,
 boolean configureOnly)
              throws IOException

Load the persistent data into all SerializableManagedObjects that are available in the MOServer provided during construction and that are not SerializableManagedObject.isVolatile(). However, if the parameter configureOnly is true and SerializableManagedObject.isConfigurable() is true, then these objects are changed too if present in input.

Parameters:

input - the data to load.

configureOnly - specifies the kind of data to be loaded. If true then SerializableManagedObject.isConfigurable() objects are loaded even if they are SerializableManagedObject.isVolatile().

Throws:

IOException - if the input cannot be read.

saveData

public void saveData(MOOutput output)
              throws IOException

Saves the serializable data of the associated servers to the given MOOutput. This method can be called while the registrations of the MOServers are changed, because MOServer.iterator() is synchronized and returns a copy tree of the registered objects.

Parameters:

output - a MOOutput instance to store the data.

Throws:

IOException - if the output stream cannot be written.

saveData

public void saveData(MOOutput output,
 MOPriorityProvider priorityProvider)
              throws IOException

Saves the serializable data of the associated servers to the given MOOutput in the order defined by MOPriorityProvider. This method can be called while the registrations of the MOServers are changed, because MOServer.iterator() is synchronized and returns a copy tree of the registered objects.

Parameters:

output - a MOOutput instance to store the data.

priorityProvider - if not null, the objects of the servers are stored in order defined by this priority provider. Objects with lowest priority value, will be saved first.

Throws:

IOException - if the output stream cannot be written.
