CSVReader

classin packageklyn.io.csv

public class CSVReader extends Object implements IList<ArrayList<String>>:

Object

└ CSVReader

All Implemented Interfaces: IList

RFC-4180 style CSV reader inspired by Python's csv.reader.

CSVReader materializes rows as an ordered read-only list and is directly iterable with for row in reader. Quoted fields may contain delimiters, CR/LF newlines and escaped quotes.

Example

import klyn.io.csv

reader = CSVReader(StringReader("name,city\n\"Ada, A.\",London"))
for row as ArrayList<String> in reader:
print(row.join(" | "))

Constructors

Modifier and Type	Member	Description
public	CSVReader `CSVReader( filename as String, delimiter as Char = ',', quoteChar as Char = '"', escapeChar as Char = Char(0), doubleQuote as Boolean = true, skipInitialSpace as Boolean = false, strict as Boolean = true ):`	Reads and parses a CSV file.
public	CSVReader `CSVReader( path as Path, delimiter as Char = ',', quoteChar as Char = '"', escapeChar as Char = Char(0), doubleQuote as Boolean = true, skipInitialSpace as Boolean = false, strict as Boolean = true ):`	Reads and parses a CSV file.
public	CSVReader `CSVReader( reader as TextReader, delimiter as Char = ',', quoteChar as Char = '"', escapeChar as Char = Char(0), doubleQuote as Boolean = true, skipInitialSpace as Boolean = false, strict as Boolean = true ):`	Reads and parses all remaining text from a `TextReader`.

Methods

Modifier and Type	Member	Description
public override	count `count(item as ArrayList<String>) as ULong:`	Counts rows equal to `item`.
public override	join `join(separator as String) as String:`	Joins row textual representations with a separator.
public	readRow `readRow(index as Int) as ArrayList<String>:`	Returns one parsed row.
public	readRows `readRows() as ArrayList<ArrayList<String>>:`	Returns the parsed rows.
public	rows `rows() as ArrayList<ArrayList<String>>:`	Alias for `readRows()`, useful when mirroring Python examples.
public	skip `skip(count as Int) as Void:`	Skips the next parsed rows.
