Returns:

the long index value at which the element value was stored

exists

public boolean exists(long lIndex)

Description copied from interface: LongArray

Determine if the specified index is in use.

Specified by:

Parameters:

lIndex - a long index value

Returns:

true if a value (including null) is stored at the specified index, otherwise false

remove

public V remove(long lIndex)

Description copied from interface: LongArray

Remove the specified index from the LongArray, returning its associated value.

Specified by:

remove in interface LongArray<V>

Parameters:
