public DataValueListWithNulls()
public DataValueListWithNulls(int capacity)
Construct a new list with DataValueListWithNulls.length
of zero and optional initial capacity
.
A list can expand in length beyond its initial capacity, but best performance
will be obtained if the initial capacity is close to the list's maximum length.
