Constructor Detail

SimpleLatestProxyDsHandler

public SimpleLatestProxyDsHandler(String latestName,
                                  boolean locateAtTopOrBottom,
                                  InvService service,
                                  boolean isResolver)

Constructor. The latestName is used as the name of latest dataset created. The location for the placement of the latest dataset is given by locateAtTopOrBottom (true - locate on top; false - locate on bottom).

Parameters:

latestName - the name to be used for all latest dataset, if null, the default is "latest.xml".

locateAtTopOrBottom - indicates where to locate the latest dataset (true - locate on top; false - locate on bottom).

service - the InvService used by the created dataset.
