NAME

Oak::Persistent - Implements persistency in object properties

DESCRIPTION

This module is the base for all objects that needs persistency. It implements the basic functions to store the object data.

METHODS

Oak::Persistent inherits all Oak::Object methods and implements/overrides the following

after_construction

Overwritten only to call load_initial_properties, you need to call SUPER at the beggining of the function if you overrides it

load_initial_properties

This function is called at after_construction to load the properties that always will be used by the object. Simply call get with all the properties you need.

get_hash(NAME,NAME,...)

Overriden just to call load_property if the requested property is not in the object property hash.

set(NAME=>VALUE,NAME=>VALUE,...)

Overriden to call chooseFiler and store with the selected filer.

feed(NAME=>VALUE,NAME=>VALUE,...)

Defines a property without using any filer. Usefull at constructor, when you want to set the properties you will use to create the filer. Or for objects created that you already have the data (you made a optimized sql, and you have the data of severall objects), this will make the object not to use the filer to access this property.

choose_filer(NAME)

Selects the filer which works with NAME property of object. Returns the name of the filer.

test_filer(NAME)

Create the filer NAME unless exists and defined.

Oak::Persistent::Error::ErrorCreatingFiler

The filer was still undef after the creation.

EXAMPLES

use base qw(Oak::Persistent);
