Method Details

remove

public boolean remove(long ok)

Description copied from interface: LongSet

Removes an element from this set.

Specified by:

remove in interface LongSet

• Collection.remove(Object)

clone

public Object clone()

equals

public boolean equals(Object o)

Specified by:

equals in interface Collection<Long>

Specified by:

equals in interface Set<Long>

Overrides:

equals in class LongCollections.EmptyCollection

rem

@Deprecated
public boolean rem(long k)

Deprecated.

Description copied from class: AbstractLongCollection

Removes a single instance of the specified element from this collection, if it is present (optional operation).

Note that this method should be called remove(), but the clash with the similarly named index-based method in the List interface forces us to use a distinguished name. For simplicity, the set interfaces reinstates remove().

Specified by:

rem in interface LongCollection

Specified by:

rem in interface LongSet

Overrides:

rem in class AbstractLongCollection
