Method Detail

insert

public long insert(CharSequence str,
                   TripleComponentRole position)

Description copied from interface: TempDictionary

Inserts a string in the dictionary in a position

Specified by:

insert in interface TempDictionary

Parameters:

str - The string to be inserted

position - TriplePosition to be inserted in

reorganize

public void reorganize()

Description copied from interface: TempDictionary

Reorganizes the dictionary (Extract shared SO, sort sections). (used for two-pass way of work).

Specified by:

reorganize in interface TempDictionary

reorganize

public void reorganize(TempTriples triples)

This method is used in the one-pass way of working in which case it should not be used with a disk-backed dictionary because remapping requires practically a copy of the dictionary which is very bad... (it is ok for in-memory and they should override and write implementation)

Specified by:

reorganize in interface TempDictionary

public boolean isOrganized()

Specified by:

isOrganized in interface TempDictionary

clear
