TSVParser

public class TSVParser extends DataStreamParser (Code)

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

Constructor Summary
public	TSVParser(Reader in) Create a new TSVParser instance.
public	TSVParser(Reader in, List columnNames) Create a new TSVParser instance.
public	TSVParser(Reader in, List columnNames, String characterEncoding) Create a new TSVParser instance.

Method Summary
protected void	initTokenizer(StreamTokenizer tokenizer) Initialize the StreamTokenizer instance used to read the lines from the input reader.

Constructor Detail

TSVParser
public TSVParser(Reader in)(Code)
	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.

TSVParser
public TSVParser(Reader in, List columnNames)(Code)
	Create a new TSVParser instance. Requires a Reader to read the tab-separated values from, and a list of column names. Parameters: in - the input reader. Parameters: columnNames - a list of column names.

TSVParser
public TSVParser(Reader in, List columnNames, String characterEncoding)(Code)
	Create a new TSVParser instance. Requires a Reader to read the tab-separated values from, a list of column names and a character encoding. Parameters: in - the input reader. Parameters: columnNames - a list of column names. Parameters: characterEncoding - the character encoding of the input.

Method Detail

initTokenizer
protected void initTokenizer(StreamTokenizer tokenizer)(Code)
	Initialize the StreamTokenizer instance used to read the lines from the input reader. It is now only needed to set the fieldSeparator
