JAR root node matching a given URI. Not supported.

Specified by:

open in interface DrbFactoryImpl

Parameters:

uri - Not cosidered.

Returns:

Always null.

open

public DrbNode open(DrbNode base_node)

XML root node from an existing node. The provided base node shall exist and it shall be able to provide a FileInputStream implementation.

Specified by:

open in interface DrbFactoryImpl

Parameters:

base_node - The node to be considered in input.

Returns:

Drb_node

open

public DrbNode open(URL uri,
                    DrbNode base_node)

XML node matching a given URI from an existing node. This operation does not consider the uri parameter and delegate the node creation to the open(DrbNode baseNode) operation.

Specified by:

open in interface DrbFactoryImpl

Parameters:

uri - Not considered here.

base_node - The input node to be used as context or base.
