`protected static Logger (src)`	`log`

Constructor Summary
`XMLFilePersistenceManager()`

Method Summary
`protected java.io.File`	`getStoreFile(MBeanInfo (src) metadata, boolean createFile)` Obtain the store location from the ModelMBean Descriptor.
`protected boolean`	`isLoading()`
`void`	`load(ModelMBeanInvoker (src) mbean, MBeanInfo (src) metadata)` Loads the attributes from the given file
`protected void`	`setIsLoading(boolean newIsLoading)`
`void`	`store(MBeanInfo (src) metadata)` What we need to get here is 1) the persist location, and 2) the entire contents of the mbean.

Method Detail

load

public void load(ModelMBeanInvoker (src)  mbean,
                 MBeanInfo (src)  metadata)
          throws MBeanException (src)

Loads the attributes from the given file

Specified by:: load in interface PersistenceManager (src)

Parameters:: mbean - to store to; metadata - with file location etc.
Throws:: MBeanException (src)

store

public void store(MBeanInfo (src)  metadata)
           throws MBeanException (src)

What we need to get here is 1) the persist location, and 2) the entire contents of the mbean. #2 contains the entire contents (state) of the model object, as well as the meta data that the mbean provides. As such, serializing this (MBeanInfo) object (brute force) in effect serializes the model as well.

Specified by:: store in interface PersistenceManager (src)

Parameters:: metadata -
Throws:: MBeanException (src)

isLoading

protected boolean isLoading()

setIsLoading

protected void setIsLoading(boolean newIsLoading)

getStoreFile

protected java.io.File getStoreFile(MBeanInfo (src)  metadata,
                                    boolean createFile)
                             throws MBeanException (src)

Obtain the store location from the ModelMBean Descriptor. If the file name does not end on ".xml", it will be converted to do so.
