Method Detail

export

public MessagePassingOutgoingPush export(IncomingPush incomingPushItf,
                                         Map<String,Object> hints)
                                  throws ExportException
Description copied from interface: MessagePassingProtocol
Creates an access point and returns an interface that can be used to send messages through it. Messages received on this access point will be passed to the given IncomingPush interface.

Specified by:
export in interface MessagePassingProtocol
Parameters:
incomingPushItf - the interface on which message received on the created access point will be passed, may be null.
hints - additional parameters, can be null.
Returns:
an interface which can be used to send messages through the created access point
Throws:
ExportException - if the export process fails.

public ExportIdentifier createExportIdentifier(Map<String,Object> info,
                                               ExportIdentifier[] next)
                                        throws InvalidExportIdentifierException
Description copied from interface: Protocol
Creates a new export identifier with the provided info

Specified by:
createExportIdentifier in interface Protocol
Parameters:
info - the info used to create the export identifier.
next - the export identifier of the lower level protocols.
Returns:
a new export identifier.
Throws:
InvalidExportIdentifierException - if the export identifier can't be created.
