NAME

App::PipeFilter::JsonMap - map input fields to output fields by renaming them

VERSION

version 0.005

SYNOPSIS

#!/usr/bin/perl
use App::PipeFilter::JsonMap;
exit App::PipeFilter::JsonMap->new_with_options()->run();

DESCRIPTION

App::PipeFilter::JsonMap implements the jmap(1) pipeline filter. It renames JSON object fields by mapping input field names to new ones on output.

This class subclasses App::PipeFilter::Generic::Json.

PUBLIC ATTRIBUTES

i

The i() attribute holds an arrayref of one or more input fields to be renamed. All other input fields will be present in the resulting output without being renamed. MooseX::Getopt sets i() to the values of the -i options from the command line.

o

The o() attribute holds an arrayref of the new names of the fields from i(). Both i() and o() must have the same number of field names. MooseX::Getopt sets o() to the values of the -o options from the command line.

PUBLIC METHODS

transform

The transform() method renames the fields named in the i() attribute to the names found in the o() attribute.
