Interface ApplicationImportHandler

All Superinterfaces:

ApplicationExpImportHandler

All Known Implementing Classes:

ApplicationImportHandlerTemplate, ContainerTemplateHandler, NMHandler

public interface ApplicationImportHandler

extends ApplicationExpImportHandler

This interface represents application specific implementation of how import process gets input information. There are two types of imput information for import process:

• XML files representing objects for import
• Content files for objects, that are content holders

Any import application must implement such a handler and supply it to import service.

To improve performance of import process there are two different methods, that import service uses to get input information:

• InputStream getContentAsInputStream (String contentId) throws WTException;
• ApplicationData getContentAsApplicationData (String contentId) throws WTException;

The first method represents a general regular way how import service can get input information.
The second method represents rather specific way, that allows improve performance in some specific cases (particularely, in Replication import implementation). If application can not or does not want to use this method then this method should return null.

Method Detail

getContentAsInputStream

public InputStream getContentAsInputStream(String contentId)
                                    throws WTException

Returns InputStream representing input information for import process

Supported API: true

Parameters:

contentId - The unique id to identify the content data, such as the file name (including the path) in a jar file.

Returns:

InputStream

Throws:

WTException

getContentAsApplicationData

public ApplicationData getContentAsApplicationData(String contentId)
                                            throws WTException

Returns ApplicationData representing input information for import process. Import application does not have really implement this method. It can simple return null.

Supported API: true

Parameters:

contentId - The unique id to identify the content data, such as the file name (including the path) in a jar file.

Returns:

ApplicationData

Throws:

WTException

importObjectNotification
