Long
constructor()
See LongSet(Int).
Construct a new set with {@link com.sap.cloud.mobile.kotlin.odata.LongSet#size LongSet.size} of zero and optional initial capacity.
A set can expand in size beyond its initial capacity, but best performance
will be obtained if the initial capacity is close to (and not less than) the set's maximum size.
Parameters
capacity
Optional initial capacity.
