public interface TempTriples
extends TriplesPrivate, Closeable

Interface for TempTriples implementation. This is a dynamic interface. For static(read-only) behaviour have a look at Triples

Method Summary

Modifier and Type	Method and Description
void	clear() Clear all triples, resulting in an empty triples section.
TripleComponentOrder	getOrder() Gets the currently set order(TripleComponentOrder)
boolean	insert(int subject, int predicate, int object) Add one triple
boolean	insert(TripleID... triples) Adds one or more triples
void	load(Triples triples, ProgressListener listener) Load triples from another instance.
boolean	remove(TripleID... pattern) Deletes one or more triples according to a pattern
void	removeDuplicates(ProgressListener listener)
void	setOrder(TripleComponentOrder order) Sets a type of order(TripleComponentOrder)
void	sort(ProgressListener listener) Sorts the triples based on the order(TripleComponentOrder) of the triples.
boolean	update(TripleID triple, int subj, int pred, int obj) Updates the given TripleID with the new values.

Method Detail

insert

boolean insert(int subject,
               int predicate,
               int object)

Add one triple

Parameters:

subject -

predicate -

object -

Returns:

insert

boolean insert(TripleID... triples)

Adds one or more triples

Parameters:

triples - The triples to be inserted

Returns:

boolean

update

boolean update(TripleID triple,
               int subj,
               int pred,
               int obj)

Updates the given TripleID with the new values. The control has to be given over this method to the TempTriples implementation instead of changing the triple manually because some implementations might not react well to that (TriplesSet for example, changing the triple will not trigger reordering)

Parameters:

triple -

subj -

pred -

obj -

Returns:

remove

boolean remove(TripleID... pattern)

Deletes one or more triples according to a pattern

Parameters:

pattern - The pattern to match against

Returns:

boolean

sort

void sort(ProgressListener listener)

Sorts the triples based on the order(TripleComponentOrder) of the triples. If you want to sort in a different order use setOrder first.

removeDuplicates

void removeDuplicates(ProgressListener listener)

setOrder

void setOrder(TripleComponentOrder order)

Sets a type of order(TripleComponentOrder)

Parameters:

order - The order to set

getOrder

TripleComponentOrder getOrder()

Gets the currently set order(TripleComponentOrder)

clear

void clear()

Clear all triples, resulting in an empty triples section.

load

void load(Triples triples,
          ProgressListener listener)

Load triples from another instance.
