Interface ExportManager

All Known Implementing Classes:

DefaultExportManager

public interface ExportManager

While ExportService is purely in charge of CRUD-related operations on Export, this service is a higher level abstraction that performs the surrounding logic of processing export operations. This includes processing requests and emitting the required messages. It internally delegates to ExportService for CRUD operations.

Resource services should directly interact with this manager rather than the ExportService for export processing.

For actual processing of exports, the manager delegates to ExportProcessor, and for writing the files, the manager delegates to the ExportFileWriter.

Method Detail

initiateExport

Export initiateExport(ExportRequest request,
                      String target,
                      @Nullable
                      String filterString,
                      @Nullable
                      com.broadleafcommerce.data.tracking.core.context.ContextInfo contextInfo)

This method accepts an export request and the context of the request to build a Export and persist it in the data store.

Sends a ProcessExportRequest message to request that the export be processed.

Parameters:

request - a request to perform an Export.

For each of the "exporting context" fields describing where the operation will be performed, the default implementation will first check if the field is supplied in ExportRequest, and if not, use the value from the ContextInfo.

target - the target of the export. This is some value that can be mapped to a particular domain by the logic performing an export, rather than explicitly requiring the fully qualified classname. Used to populate Export.target.

filterString - the filter string that should be used to find the records to export. Used to populate Export.filterString.

contextInfo - context information surrounding sandboxing and multitenant state

Returns:

the newly created Export

Throws:

com.broadleafcommerce.common.error.validation.ValidationException - if the request failed validation

IllegalArgumentException - if request is null or target is blank

com.broadleafcommerce.data.tracking.core.exception.NotVisibleException - if the currently authenticated user is not permitted to perform an export in the final determined exporting context

processExport

void processExport(Export export)

Performs an Export, processing the requested records and writing the file in batches while updating the status for the Export as it goes.

Note: this method should always be called with the result of ExportService.setProcessingStatus(String) if the value is not null.

The ExportManager will delegate processing to the first ExportProcessor for which ExportProcessor.canHandle(Export) returns true. Thus if more than one ExportProcessor can handle a request, the bean registered with the higher priority will be used.

The ExportManager will delegate file writing to the first ExportFileWriter for which ExportFileWriter.canHandle(Export) returns true. Thus if more than one ExportFileWriter can handle a request, the bean registered with the higher priority will be used.

Parameters:

export - the export to perform - this should always be the result of ExportService.setProcessingStatus(String) if it is not null
