contains

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({'â¥' => 'mojolicious'})−>contains('/â¥');
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({'â¥' => 'mojolicious'})−>contains('/â');
Mojo::JSON::Pointer−>new({foo => 'bar', baz => [4, 5]})−>contains('/bar');
Mojo::JSON::Pointer−>new({foo => 'bar', baz => [4, 5]})−>contains('/baz/9');

get

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({'â¥' => 'mojolicious'})−>get('/â¥');
# "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');

new

my $pointer = Mojo::JSON::Pointer−>new;
my $pointer = Mojo::JSON::Pointer−>new({foo => 'bar'});
