public class TextFileObjectStore
extends InMemoryObjectStore<String>

A Simple object store that stores String objects by key to a text file. This store is only suitable for storing simple key value pair strings. This store is backed by an in-memory store and supports the ability to expire and apply TTL to objects in the store.

Method Detail

isPersistent

public boolean isPersistent()

Is this store persistent?

Specified by:

isPersistent in interface ObjectStore<String>

Overrides:

isPersistent in class InMemoryObjectStore<String>

Returns:

true if this store is persistent

initialise

public void initialise()
                throws InitialisationException

Description copied from interface: Initialisable

Method used to perform any initialisation work. If a fatal error occurs during initialisation an InitialisationException should be thrown, causing the Mule instance to shutdown. If the error is recoverable, say by retrying to connect, a RecoverableException should be thrown. There is no guarantee that by throwing a Recoverable exception that the Mule instance will not shut down.

Specified by:

initialise in interface Initialisable

Overrides:

initialise in class AbstractMonitoredObjectStore<String>

Throws:

InitialisationException - if a fatal error occurs causing the Mule instance to shutdown

RecoverableException - if an error occurs that can be recovered from

loadFromStore

protected void loadFromStore()
                      throws Exception

Throws:

Exception

store

public void store(Serializable id,
                  String item)
           throws ObjectStoreException

Description copied from interface: ObjectStore

Store the given Object.

Specified by:

store in interface ObjectStore<String>

Overrides:

store in class InMemoryObjectStore<String>

Parameters:

id - the identifier for value

item - the Object to store with key

Throws:

ObjectStoreException - if the given key cannot be stored or is null.

ObjectStoreNotAvaliableException - if the store is not available or any other implementation-specific error occured.

ObjectAlreadyExistsException - if an attempt is made to store an object for a key that already has an object associated.

getDirectory

public String getDirectory()

setDirectory

public void setDirectory(String directory)

getEncoding

public String getEncoding()

setEncoding

public void setEncoding(String encoding)

dispose

public void dispose()

Description copied from interface: Disposable

A lifecycle method where implementor should free up any resources. If an exception is thrown it should just be logged and processing should continue. This method should not throw Runtime exceptions.

Specified by:

dispose in interface Disposable

Overrides:

dispose in class AbstractMonitoredObjectStore<String>
