Method Detail

getInt

public int getInt(long i)

Description copied from interface: IntBigList

Returns the element at the specified position.

Specified by:

getInt in interface IntBigList

See Also:

BigList.get(long)

rem

public boolean rem(int k)

Description copied from class: AbstractIntCollection

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.
