Mojo::JSON::Pointer - JSON Pointers

  use Mojo::JSON::Pointer;
  my $pointer = Mojo::JSON::Pointer->new({foo => [23, 'bar']});
  say $pointer->get('/foo/1');
  say 'Contains "/foo".' if $pointer->contains('/foo');

Mojo::JSON::Pointer is an implementation of RFC 6901 <http://tools.ietf.org/html/rfc6901>.

Mojo::JSON::Pointer implements the following attributes.

  my $data = $pointer->data;
  $pointer = $pointer->data({foo => 'bar'});
Data structure to be processed.

Mojo::JSON::Pointer inherits all methods from Mojo::Base and implements the following new ones.

  my $bool = $pointer->contains('/foo/1');
Check if "data" contains a value that can be identified with the given JSON Pointer.
  # True
  Mojo::JSON::Pointer->new('just a string')->contains('');
  Mojo::JSON::Pointer->new({'♥' => 'mojolicious'})->contains('/♥');
  Mojo::JSON::Pointer->new({foo => 'bar', baz => [4, 5]})->contains('/foo');
  Mojo::JSON::Pointer->new({foo => 'bar', baz => [4, 5]})->contains('/baz/1');
  # False
  Mojo::JSON::Pointer->new({'♥' => 'mojolicious'})->contains('/☃');
  Mojo::JSON::Pointer->new({foo => 'bar', baz => [4, 5]})->contains('/bar');
  Mojo::JSON::Pointer->new({foo => 'bar', baz => [4, 5]})->contains('/baz/9');

  my $value = $pointer->get('/foo/bar');
Extract value from "data" identified by the given JSON Pointer.
  # "just a string"
  Mojo::JSON::Pointer->new('just a string')->get('');
  # "mojolicious"
  Mojo::JSON::Pointer->new({'♥' => 'mojolicious'})->get('/♥');
  # "bar"
  Mojo::JSON::Pointer->new({foo => 'bar', baz => [4, 5, 6]})->get('/foo');
  # "4"
  Mojo::JSON::Pointer->new({foo => 'bar', baz => [4, 5, 6]})->get('/baz/0');
  # "6"
  Mojo::JSON::Pointer->new({foo => 'bar', baz => [4, 5, 6]})->get('/baz/2');

  my $pointer = Mojo::JSON::Pointer->new;
  my $pointer = Mojo::JSON::Pointer->new({foo => 'bar'});
Build new Mojo::JSON::Pointer object.
