Myco::Entity Description

Myco::Entity is a common base class for all Myco entity classes. Myco::Entity is a common base class for all Myco entity classes.SYNOPSIS ### Entity class definition package Myco::Foo; use base qw(Myco::Entity); # Start building metadata my $metadata = Myco::Entity::Meta->new ( name => __PACKAGE__, tangram => { table => 'Foo' } ); $metadata->add_attribute(name => 'attr1', type => 'string'); $metadata->add_attribute(name => 'attr2', type => 'string'); # class-specific methods defined ... # # Fill in $schema with all added_attributes and discover other metadata $metadata->activate_class; ### Entity class usage use Myco::Foo; # Constructor $obj = Myco::Foo->new; $obj = Myco::Foo->new(attr1 => value, attr2 => value); # Access class metadata (see Myco::Entity::Meta) $meta = Myco::Foo->introspect; $meta = $obj->introspect; # Accessors $obj->get_attr1; # get attribute value $obj->set_attr1('value'); # set attribute value # Instance methods $id = $obj->save; # update object's state in persistent # storage, create new record if needed; # returns object's Tangram id $obj->destroy; $obj->modify(attr1 => val, attr2 => val); $object_id = $obj->id; $obj->is_transient; # returns true if object is in Tangram # transient storage ## object retrieval (see class Myco documentation # for full detail) $obj = Myco->load($object_id); # fetch all objects of given type @objects = Myco->select(ref $obj);Provides, via inheritence, common interface in support of basic lifecycle needs for myco entity objects.This is accomplished through the encapsulation of the CPAN module Class::Tangram which provides a basis for "in-memory" object behavior. Consult its documentation for details on schema definition syntax, getter/setter behavior, check functions, etc.The common interface for object persistence behavior (referred within myco as "transaction" behavior) is provided through defintion of a handful of related instance methods. This is done with reliance on the services of the class Myco, which encapsulates the functionality of Tangram::Storage and provides system-wide connection handling. Requirements: · Perl
