SYNOPSIS

            

              
              
package App::PipeFilter::Generic::Json;
use Moose;
extends 'App::PipeFilter::Generic';
with qw(
  App::PipeFilter::Role::Reader::Sysread
  App::PipeFilter::Role::Input::Json
  App::PipeFilter::Role::Output::Json
);

DESCRIPTION

App::PipeFilter::Role::Reader::Sysread implements a read_input() method that returns large chunks of input at a time. Input chunks are arbitrary; they do not honor the structure of the files being read.

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

This role is faster than App::PipeFilter::Role::Reader::LineByLine, but it may not work with all devices. Some data formats may be easier to work with on a line-by-line basis.

PUBLIC METHODS

read_input FILEHANDLE, SCALAR_REF

read_input() reads the next chunk of data from a FILEHANDLE using Perl's built-in sysread() function. It appends this chunk of data to the buffer pointed at by a SCALAR_REF. It returns sysread()'s result.
