  com.penguinwerks.jodene.data.DataReader
      com.penguinwerks.jodene.data.FileDataReader

All Implemented Interfaces:

java.io.Serializable

public class FileDataReader

extends DataReader

implements java.io.Serializable

Reads in data from a file. This Data Reader reads in data from a delimited file. The delimiter is configurable and is, by default, ',' (comma). The reader reads in a line at a time and splits the line into an array of trimmed strings. Until the end of the file, it reads a line, translates it, scales it and adds it to the list of results.
