Method NewAnonymous

NewAnonymous(Func<DocIdSetIterator>)

Creates a new instance with the ability to specify the body of the GetIterator() method through the getIterator parameter. Simple example:

    var docIdSet = DocIdSet.NewAnonymous(getIterator: () =>
    {
        OpenBitSet bitset = new OpenBitSet(5);
        bitset.Set(0, 5);
        return new DocIdBitSet(bitset);
    });
