Method Detail

load

public Node load(Reference vref)
          throws IOException,
                 UnknownReferenceException

Description copied from class: AbstractXMLStore

Resolves any RelativeReferences and calls AbstractXMLStore.resolvedLoad(org.planx.xmlstore.Reference).

Specified by:

load in interface XMLStore

Overrides:

load in class AbstractXMLStore

Parameters:

vref - the Reference to the data

Returns:

node representing the loaded XML data

Throws:

IOException - if an error occurs during disk, network, etc access

UnknownReferenceException - if the data referenced is not stored in the XMLStore or the Reference is of a type not supported by the XMLStore

close

public void close()
           throws IOException

Description copied from interface: XMLStore

The method is used to let the XMLStore properly commit all data to the underlying ressource, release resources, and so forth. Once close has been issued on an XMLStore, the store is no longer available for handling requests. Any subsequent request to the store will result in an exception being thrown. An XMLStore implementation has to ensure that this happens.

Specified by:

close in interface XMLStore

Overrides:

close in class AbstractXMLStore

Throws:

IOException - if it is not possible to properly close the store
