                      throws SnapshotException

Description copied from interface: ICollectionExtractor

Returns the object ids (int) for all objects which are contained in the collection

Specified by:

extractEntryIds in interface ICollectionExtractor

Overrides:

extractEntryIds in class WrapperCollectionExtractor

Returns:

Throws:

SnapshotException

extractMapEntries

public Iterator<Map.Entry<IObject,IObject>> extractMapEntries(IObject coll)

Description copied from interface: IMapExtractor

Extracts the contents of a map (i.e. an IObject representing a Map) and provides an Iterator over them

Specified by:

extractMapEntries in interface IMapExtractor

Overrides:

extractMapEntries in class WrapperMapExtractor

Parameters:

coll - - the map to extract contents from

Returns:

an Iterator over the entries. If the original Map had an Entry object, the content of the iterator would usually be EntryObject
