CsvInStream

@Js
class CsvInStream : InStream

CsvInStream is used to read delimiter-separated values as specified by RFC 4180. Format details:

  • rows are delimited by a newline
  • cells are separated by delimiter char
  • cells may be quoted with " character
  • quoted cells may contain the delimiter
  • quoted cells may contain newlines (always normalized to "\n")
  • quoted cells must escape " with ""
  • the trim flag trims leading/trailing whitespace from non-quoted cells (note that RFC 4180 specifies that whitespace is significant)

Also see CsvOutStream.

 constructors make

Wrap the underlying input stream

 fields trim

Configures whether unqualified whitespace around a cell is automatically trimmed

 delimiter

Delimiter character

 methods readRow

Read the next line as a row of delimiter-separated strings

 eachRow

Iterate through all the lines parsing each one into delimited-separated strings and calling the given callback functions

 readAllRows

Read the entire table of rows into memory

 delimiter Int : delimiter

Delimiter character; defaults to comma.

 eachRow Void eachRow(|Str[]| f)

Iterate through all the lines parsing each one into delimited-separated strings and calling the given callback functions. The input stream is guaranteed to be closed upon completion.

 make new make(InStream in)

Wrap the underlying input stream.

 readAllRows Str[][] readAllRows()

Read the entire table of rows into memory. The input stream is guaranteed to be closed upon completion.

 readRow virtual Str[]? readRow()

Read the next line as a row of delimiter-separated strings. Return null if at end of stream.
