Class TSVParser

- All Implemented Interfaces:

,org.apache.avalon.framework.logger.LogEnabled
TSVParser is used to parse a stream with tab-separated values and
generate ParameterParser objects which can be used to
extract the values in the desired type.
The class extends the abstract class DataStreamParser and implements initTokenizer with suitable values for TSV files to provide this functionality.
The class (indirectly through DataStreamParser) implements the java.util.Iterator interface for convenience. This allows simple use in a Velocity template for example:
#foreach ($row in $tsvfile) Name: $row.Name Description: $row.Description #end

TSVParser
Create a new TSVParser instance. Requires a Reader to read the tab-separated values from. The column headers must be set independently either explicitly, or by reading the first line of the TSV values.- Parameters:
in
- the input reader.
