NAME

PGObject::Type::JSON - JSON wrappers for PGObject

VERSION

Version 2.0.1

SYNOPSIS

   PGOBject::Type::JSON->register();

Columns of type json will be converted into hashrefs

   my $obj =  PGOBject::Type::JSON->new($hashref);

$obj will now serialize to the database as json.

DESCRIPTION

This module allows json types or others (specified by custom register) types to be converted from JSON into objects according to their values.

This module assumes that encoding will be in UTF8 across the board and is not safe to use with other database encodings.

SUBROUTINES/METHODS

register(registry => 'default', types => ['json'])

new($ref)

Stores this as a reference. Currently database nulls are stored as cyclical references which is probably a bad idea. In the future we should probably have a lexically scoped table for this.

from_db

serializes from the db. Note that database nulls are preserved distinct from json null's.

to_db

returns undef if is_null. Otherwise returns the value encoded as JSON

reftype

Returns the reftype of the object (i.e. HASH, SCALAR, ARRAY)

is_null

Returns true if is a database null.
