Method Detail

addIOHandler

void addIOHandler(IOHandler ioHandler)

Adds the specified handler to the list of handlers.

Parameters:

ioHandler - to be added

getIOHandlers

IOHandler[] getIOHandlers()

Returns all handlers that have been added to this manager.

Returns:

Array of all handlers

importContent

boolean importContent(ImportContext context,
                      boolean isCollection)
                      throws IOException

Passes the specified context and boolean value to the IOHandlers present on this manager. As soon as the first handler incidates success the import should be considered completed. If none of the handlers can deal with the given information this method must return false.

Parameters:

context -

isCollection -

Returns:

true if any of the handlers import the given context. False otherwise.

Throws:

IOException

boolean importContent(ImportContext context,
                      DavResource resource)
                      throws IOException

Passes the specified information to the IOHandlers present on this manager. As soon as the first handler incidates success the import should be considered completed. If none of the handlers can deal with the given information this method must return false.

Parameters:

context -

resource -

Returns:

true if any of the handlers import the information present on the specified context.

Throws:

IOException

exportContent

boolean exportContent(ExportContext context,
                      boolean isCollection)
                      throws IOException

Passes the specified information to the IOHandlers present on this manager. As soon as the first handler incidates success the export should be considered completed. If none of the handlers can deal with the given information this method must return false.

Parameters:

context -

isCollection -

true if any of the handlers could run the export successfully, false otherwise.

Throws:

IOException

boolean exportContent(ExportContext context,
                      DavResource resource)
                      throws IOException

Passes the specified information to the IOHandlers present on this manager. As soon as the first handler incidates success the export should be considered completed. If none of the handlers can deal with the given information this method must return false.

Parameters:
