METHODS
Mojo::JSON::Pointer inherits all methods from Mojo::Base and implements the following new ones.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({'♥' => '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');
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({'♥' => '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');
new
my $pointer = Mojo::JSON::Pointer->new; my $pointer = Mojo::JSON::Pointer->new({foo => 'bar'});
