All Implemented Interfaces:

InputFormat<Record,FileInputSplit>, Serializable

public class PointInFormat
extends DelimitedInputFormat

Generates records with an id and a and CoordVector. The input format is line-based, i.e. one record is read from one line which is terminated by '\n'. Within a line the first '|' character separates the id from the the CoordVector. The vector consists of a vector of decimals. The decimals are separated by '|' as well. The id is the id of a data point or cluster center and the CoordVector the corresponding position (coordinate vector) of the data point or cluster center. Example line: "42|23.23|52.57|74.43| Id: 42 Coordinate vector: (23.23, 52.57, 74.43)
