All Implemented Interfaces:

TableReader

public class DelimitedTextTableReader
extends AbstractTextTableReader

TableReader for delimited text files, such as tab-delimited or pipe-delimited text files. Such files typically list one row of table data per line of the file, using a designated character such as a tab (\t) or pipe (|) to demarcate different data columns. This class allows you to select any regular expression as the column delimiter.
