public class LongScatterSet
extends LongHashSet

Same as LongHashSet 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

public static LongScatterSet from(long... elements)

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

removeAll

public int removeAll(LongLookupContainer c)

Default implementation uses a predicate for removal.

Specified by:

removeAll in interface LongCollection

Returns:

Returns the number of removed elements.

retainAll

public int retainAll(LongLookupContainer c)

Default implementation uses a predicate for retaining.

Specified by:

retainAll in interface LongCollection

Returns:

Returns the number of removed elements.

retainAll

public int retainAll(LongPredicate predicate)

Default implementation redirects to LongCollection.removeAll(LongPredicate) and negates the predicate.

Specified by:

retainAll in interface LongCollection

Returns:

Returns the number of removed elements.

toString

public java.lang.String toString()

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

Overrides:
