All Implemented Interfaces:

LinebasedParser<FloatVector>, Parser<FloatVector>, Parameterizable

public class FloatVectorLabelParser
extends NumberVectorLabelParser<FloatVector>

Provides a parser for parsing one point per line, attributes separated by whitespace.

Numerical values in a line will be parsed as double values but used in float precision only.

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

An index can be specified to identify an entry to be treated as class label. This index counts all entries (numeric and labels as well) starting with 0.
