Class BitVectorLabelParser

java.lang.Object

de.lmu.ifi.dbs.elki.datasource.parser.AbstractParser

de.lmu.ifi.dbs.elki.datasource.parser.BitVectorLabelParser

All Implemented Interfaces:

Parser, Parameterizable

@Title(value="Bit Vector Label Parser")
@Description(value="Parses the following format of lines:\nA single line provides a single BitVector. Bits are separated by whitespace. Any substring not containing whitespace is tried to be read as Bit. If this fails, it will be appended to a label. (Thus, any label must not be parseable as Bit.) Empty lines and lines beginning with \"#\" will be ignored. If any BitVector differs in its dimensionality from other BitVectors, the parse method will fail with an Exception.")
public class BitVectorLabelParser
extends AbstractParser
implements Parser

Provides a parser for parsing one BitVector per line, bits separated by whitespace.

Several labels may be given per BitVector. A label must not be parseable as Bit. Lines starting with "#" will be ignored.
