NAME

T2::Storage - Database handle, object cache

CONTENTS

SYNOPSIS



  # load the application schema, connect to the database
  my $storage = T2::Storage->open("MyApp");

  # store an object with a schema
  $storage->insert($object);



DESCRIPTION

The Tangram T2 Storage class. Currently, this is a subclass of Tangram::Storage, but it is planned to slowly move pieces of Tangram proper into this new core.

METHODS

<B>T2::Storage->open($site, B>$schema<B>)B> This function opens a connection to a named database source. It takes between one and two parameters:
<B>B>$site<B>B> The ‘site’ to connect to. This is a named data source, a bit like using ODBC but stored in a text file rather than an opaque registry. This should correspond to a file in etc/ called $site.dsn, as extracted by T2::Storage::get_dsn_info (see get_dsn_info).
<B>B>$schema<B>B> This should be either a Tangram::Schema object, or a T2::Schema object.

  Gets the database information for <B>B>$site_name<B>B>, in the form ($dsn, $username, $password, $schema); If $dont_get_schema is set, no attempt to load the Tangram schema is made.

Returns the site name that was used to connect to this database.

Save an object to the database (that is, do an insert if this is a new object or an update if it is already persistent).

unload_all()

A smarter version of unload_all() that really makes sure all objects are cleaned up from memory, using Class::Tangram’s clear_refs() method.

rollback_all

Make double damned sure that this instance of the Storage handle doesn’t hold any locks

dbi_handle()

Returns a current DBI handle, though you are not guaranteed to get Tangram’s own handle.
