Interface BunchMap

All Known Implementing Classes:

HashedBunchMap, WrappedHashMap

public interface BunchMap

A pruned (and slightly stewed) version of Map, containing just those operations required by NodeToTriplesMaps. BunchMaps contain only TripleBunch's.

Method Summary

Modifier and Type	Method and Description
void	clear() Clear this map: all entries are removed.
TripleBunch	get(Object key) Answer the TripleBunch associated with key, or null if there isn't one.
TripleBunch	getOrSet(Object key, Function<Object,TripleBunch> setter) Get the key and return the value found there; if nothing, calculate the value and insert.
ExtendedIterator<Object>	keyIterator() Answer an iterator over all the keys in this map.
void	put(Object key, TripleBunch value) Associate key and value.
void	remove(Object key) Remove any association for key; get on this key will now deliver null.
long	size() The number of items in the bunch.

Method Detail

clear

void clear()

Clear this map: all entries are removed.

size

long size()

The number of items in the bunch.

get

TripleBunch get(Object key)

Answer the TripleBunch associated with key, or null if there isn't one.

put

void put(Object key,
         TripleBunch value)

Associate key and value. Any existing association of key is lost. get on this key will now deliver this value.

getOrSet

TripleBunch getOrSet(Object key,
                     Function<Object,TripleBunch> setter)

Get the key and return the value found there; if nothing, calculate the value and insert. Return the value now the slot.

remove

void remove(Object key)

Remove any association for key; get on this key will now deliver null.

keyIterator

ExtendedIterator<Object> keyIterator()

Answer an iterator over all the keys in this map.
