export

public void export(DnDParameter parameter)

Description copied from interface: ExportHandler

This method is responsible for generating the data that should be transported with the event and putting them into it. The data has to be set into the datastore of the event straight forward in this call. While this event is active is the only time we have write access to the datastore. If generating the data takes to long it may be better to store some kind of reference to the data in the event. That is also the reason why all registered export handler have to generate and write their data into the datastore at the beginning of the dragEvent.

Specified by:

export in interface ExportHandler

Parameters:

parameter - The parameter containing the event.

exportDone

public void exportDone(DnDParameter parameter)

Description copied from interface: ExportHandler

This method is called when all exportHandler finished their exports.

Specified by:

exportDone in interface ExportHandler

Parameters:

parameter - The parameter containing the event.
