Method Detail

resolvedLoad

protected Node resolvedLoad(Reference vref)
                     throws IOException,
                            UnknownReferenceException

Description copied from class: AbstractXMLStore

Called by AbstractXMLStore.load(org.planx.xmlstore.Reference) after resolving RelativeReferences.

Overrides:

resolvedLoad in class AbstractXMLStore

Parameters:

vref - the resolved Reference

Throws:

IOException

UnknownReferenceException

save

public Reference save(Node node)
               throws IOException

The subtree rooted at the specified Node is sent to the remote XMLStore and saved there. A Reference to the root is returned.

Specified by:

save in interface XMLStore

Overrides:

save in class AbstractXMLStore

Parameters:

node - representing XML data in the form of semi-structured tree data

Returns:

a reference to the saved node/tree

Throws:

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

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

toString

public String toString()

Overrides:

toString in class AbstractXMLStore

checkClosed

protected void checkClosed()

Overrides:

checkClosed in class AbstractXMLStore
