Description copied from interface: Index

Freezes the index. From this point data can be inserted, searched and deleted. The index might deteriorate at some point so every once in a while it is a good idea to rebuild the index. A PivotSelector must be executed before calling this method.

Specified by:

freeze in interface Index<O extends OB>

Overrides:

freeze in class AbstractPivotOBIndex<O extends OB>

Throws:

AlreadyFrozenException - If the index was already frozen and the user attempted to freeze it again

IllegalIdException - This exception is left as a Debug flag. If you receive this exception please report the problem to: http://code.google.com/p/obsearch/issues/list

OBStorageException - If something goes wrong with the DB

OutOfRangeException - If the distance of any object to any other object exceeds the range defined by the user.

IllegalAccessException - If there is a problem when instantiating objects O

InstantiationException - If there is a problem when instantiating objects O

OBException - User generated exception

PivotsUnavailableException

IOException - if the index serialization process fails
