Interface AttributeExporterImporter

All Known Implementing Classes:

AttributeExporterImporterTemplate

public interface AttributeExporterImporter

Interface for all attribute handrlers for export and import.Some attributes are common for some object classes, in this case the implementation of export/import this attribute should implements this interface so that it can be re-useable.

Supported API: true

Extendable: false

void	finalizeCheckConflicts(Importer importer) Called in the end of conflict check process.
void	finalizeExport(Exporter exporter) This method will be called by the application handler after all objects have been exported.
void	finalizeImport(Importer importer) Called in the end of the whole ipport process to execute any import process finalization.
Object	importAttribute(Object ob, IxbElement fileXML, Importer importer) Imports all available attributes from fileXML into the object in context given by importer parameter.
void	prepareForCheckConflicts(Importer importer) Called in the beginning of conflict check process prior to the real import or preview.
