Int2IntMaps

public Int2IntMaps()

Methodendetails

empty

empty map of desired type

fastIterator

public static ObjectIterator<Int2IntMap.Entry> fastIterator(Int2IntMap map)

Helper method that provides the fastIterator that recycles a single Entry to increase throughput.

Parameter:

map - the map the fastIterator should be accessed from

Gibt zurück:

either a normal iterator if it does not support this feature to a fastIterator

fastIterable

public static ObjectIterable<Int2IntMap.Entry> fastIterable(Int2IntMap map)

Helper method that provides the fastIterable that recycles a single Entry to increase throughput.

Parameter:

map - the map the fastIterable should be accessed from

Gibt zurück:

either a normal iterable if it does not support this feature to a fastIterable

fastForEach

public static void fastForEach(Int2IntMap map,
 Consumer<Int2IntMap.Entry> action)

A Helper function that provides a faster forEach iterator implementation that recycles the entry to increase throughput

Parameter:

map - the map the fast forEach should be accessed from
