NAME ^

App::PipeFilter::Role::Reader::LineByLine - read input streams one line at a time

VERSION ^

version 0.005

SYNOPSIS ^

This is not a complete module.

  package App::PipeFilter::MysqlToJson;

  use Moose;

  extends 'App::PipeFilter::Generic';
  with qw(
    App::PipeFilter::Role::Reader::LineByLine
    App::PipeFilter::Role::Output::Json
    App::PipeFilter::Role::Transform::None
  );

  ... implementation goes here ....

DESCRIPTION ^

App::PipeFilter::Role::Reader::LineByLine implements a read_input() method that returns one line of input at a time.

App::PipeFilter::Generic uses read_input() to consume data from its current input filehandle.

This role is recommended whenever the input data source or stream format are not easy to parse in chunks. Classes should consume App::PipeFilter::Role::Reader::Sysread when possible since it is often faster.

PUBLIC METHODS ^

read_input FILEHANDLE, SCALAR_REF

read_input() reads the next line from a FILEHANDLE and appends it to the buffer pointed at by a SCALAR_REF. It returns true if it read something, or false if it reached the end of file.
