Method Detail

getLong

public long getLong(int i)

Description copied from interface: LongList

Returns the element at the specified position in this list.

Specified by:

getLong in interface LongList

See Also:

List.get(int)

rem

public boolean rem(long k)

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().

This implementation iterates over the elements in the collection, looking for the specified element and tries to remove it.

Specified by:

rem in interface LongCollection

Overrides:

rem in class AbstractLongCollection

See Also:

Collection.remove(Object)

removeLong

public long removeLong(int i)

Description copied from interface: LongList
