All Implemented Interfaces:

Parser<BitVector>, Parameterizable

public class SparseBitVectorLabelParser
extends AbstractParser<BitVector>

Provides a parser for parsing one sparse BitVector per line, where the indices of the one-bits are separated by whitespace. The first index starts with zero.

Several labels may be given per BitVector, a label must not be parseable as an Integer. Lines starting with "#" will be ignored.
