Package org.pentaho.platform.plugin.services.importexport.legacy

Class DbSolutionRepositoryImportSource

java.lang.Object

org.pentaho.platform.plugin.services.importexport.legacy.AbstractImportSource

org.pentaho.platform.plugin.services.importexport.legacy.DbSolutionRepositoryImportSource

All Implemented Interfaces:

ImportSource

public class DbSolutionRepositoryImportSource
extends AbstractImportSource

An ImportSource that connects to the legacy database-based solution repository.

This implementation works in the following way:

1. Fetch all (joined) rows in a single query.
2. Process the result set, creating files, ACLs, and possibly temporary files containing the files' data.
3. Write this info to disk in batches.
4. Close the result set.
5. Iterate over the batches, one at a time.

This implementation saves memory at the expense of disk space.

getFiles

public Iterable<ImportSource.IRepositoryFileBundle> getFiles()

Description copied from interface: ImportSource

Returns the set of files available by this Import Source.

NOTE: the Iterable object MUST support the Iterator.remove() method as the consumer of this information will be iterating over the data and will remove items that they process (and shouldn't be processed by down-stream consumers)

Returns:
