hasCollisionRatio
public boolean hasCollisionRatio()Description copied from interface:IMapExtractor
Check if the extractor can calculate collision ratio- Specified by:
hasCollisionRatio
in interfaceIMapExtractor
- Returns:
- true if @
IMapExtractor.getCollisionRatio(IObject)
could be called - See Also:
-
getCollisionRatio
Description copied from interface:IMapExtractor
Calculates the collision ratio in the collection. Could be an estimate.- Specified by:
getCollisionRatio
in interfaceIMapExtractor
- Parameters:
collection
- - the collection to calculate the collision ratio of- Returns:
- Double number of elements with colliding keys / size
- Throws:
SnapshotException
- See Also:

extractMapEntries
public Iterator<Map.Entry<IObject,IObject>> extractMapEntries(IObject collection) throws SnapshotException 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 interfaceIMapExtractor
- Parameters:
collection
- - 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
- Throws:
SnapshotException
