Class ObjectScatterSet<KType>

java.lang.Object

com.carrotsearch.hppc.ObjectHashSet<KType>

com.carrotsearch.hppc.ObjectScatterSet<KType>

All Implemented Interfaces:

ObjectCollection<KType>, ObjectContainer<KType>, ObjectLookupContainer<KType>, ObjectSet<KType>, Preallocable, java.lang.Cloneable, java.lang.Iterable<ObjectCursor<KType>>

@Generated(date="2015-05-07T09:33:04+0200",
           value="KTypeScatterSet.java")
public class ObjectScatterSet<KType>
extends ObjectHashSet<KType>

Same as ObjectHashSet but does not implement per-instance key mixing strategy and uses a simpler (faster) bit distribution function.

Note: read about important differences between hash and scatter sets.

Method Detail

from

@SafeVarargs
public static <KType> ObjectScatterSet<KType> from(KType... elements)

Create a set from a variable number of arguments or an array of Object. The elements are copied from the argument to the internal buffer.

removeAll

public int removeAll(ObjectLookupContainer<? super KType> c)

Default implementation uses a predicate for removal.

Specified by:

removeAll in interface ObjectCollection<KType>

Returns:

Returns the number of removed elements.

retainAll

public int retainAll(ObjectLookupContainer<? super KType> c)

Default implementation uses a predicate for retaining.

Specified by:

retainAll in interface ObjectCollection<KType>

Returns:

Returns the number of removed elements.

retainAll

public int retainAll(ObjectPredicate<? super KType> predicate)

Default implementation redirects to ObjectCollection.removeAll(ObjectPredicate) and negates the predicate.

Specified by:

retainAll in interface ObjectCollection<KType>

Returns:

Returns the number of removed elements.

toArray

public <T> T[] toArray(java.lang.Class<T> componentClass)

Description copied from interface: ObjectContainer

Copies all elements of this container to a dynamically created array of the given component type.

Specified by:

toArray in interface ObjectContainer<KType>

toString

public java.lang.String toString()

Convert the contents of this container to a human-friendly string.

Overrides:
