public interface SerializableStore
34
* Getst the number of objects stored and available.
41
* Will look through the files in the store directory for the oldest object serialized to disk, load it,
42
* delete the file, and return the deserialized object.
43
* Important to note that once this object is returned from this method, it is gone forever from this
44
* store and will not be able to retrieve it again without adding it back.

52
* Persists the serializable object passed to the directory specified. The file name will be the current time
53
* in milliseconds (vis System.currentTimeMillis()) with the specified suffix. This object can later be
54
* retrieved using the getNext() method, but objects will be returned in the order that they were added (FIFO).

71

78
* This will allow for change of file suffix and file path and then may start again
79
* using these new values. However, any object already written out using the old
80
* values will be lost as will not longer be accessible if these attributes are changed while stopped.
85
* This is a no op method, but needed in order to be used as a service within JBoss AS.
