Method

void addSplits(TreeSet splitKeys, byte[] prefix, int splitBits)
add Splits

TreeSet buildTreeSet(Collection elements)
build Tree Set

return new TreeSet<T>(elements);

TreeSet changeComparator(TreeSet set, Comparator cmp)
Clears the initial set, and creates a new one with same contents and has the specified comparator.

TreeSet<T> ret = new TreeSet<T>(cmp);
ret.addAll(set);
set.clear();
return ret;

String concatenate(TreeSet in)
concatenate

StringBuffer buffer = new StringBuffer();

int convertSpanToSparseGrid(final int curIx, final int span, final TreeSet indexes)
Spanning is specified in the uncompressed grid number.

final int lastIx = curIx + span;
