=head1 DESCRIPTION

This class represents organizations in Bricolage. Organizations may be the
companies for whom a person represented by a Bric::Biz::Person object works, or
an organization that owns the rights to a given asset, or with whom a product is
associated (this last use will be included in a future version).

The primary use for Bric::Biz::Org as of this writing, however, is to associate
people (Bric::Biz::Person objects) with companies and their addresses. These
associations are created by the Bric::Biz::Org add_object() method, and by the
Bric::Biz::Org::Person subclass it returns. See Bric::Biz::Org::Person for its
additions to the Bric::Biz::Org API.

=item my $org = Bric::Biz::Org->lookup({ id => $id })

Looks up and instantiates a new Bric::Biz::Org object based on the Bric::Biz::Org
object ID passed. If $id is not found in the database, lookup() returns
undef. If the ID is found more than once, lookup() throws an exception. This
should not happen.

=item my (@meths || $meths_aref) = Bric::Biz::Org->my_meths(0, TRUE)

Returns an anonymous hash of introspection data for this object. If called
with a true argument, it will return an ordered list or anonymous array of
introspection data. If a second true argument is passed instead of a first,
then a list or anonymous array of introspection data will be returned for
properties that uniquely identify an object (excluding C<id>, which is
assumed).

Each hash key is the name of a property or attribute of the object. The value
for a hash key is another anonymous hash containing the following keys:

=over 4

=item name

The name of the property or attribute. Is the same as the hash key when an
anonymous hash is returned.

=item disp

The display name of the property or attribute.

=item get_meth

attribute.

=item get_args

An anonymous array of arguments to pass to a call to get_meth in order to
retrieve the value of the property or attribute.

=item set_meth

A reference to the method that will set the value of the property or
attribute.

=item set_args

An anonymous array of arguments to pass to a call to set_meth in order to set
the value of the property or attribute.

=item type

The type of value the property or attribute contains. There are only three
types:

=over 4

=item short

=item date

=item blob

=back

=item len

If the value is a 'short' value, this hash key contains the length of the
field.

=item search

The property is searchable via the list() and list_ids() methods.

=item req

The property or attribute is required.

=item props

An anonymous hash of properties used to display the property or
attribute. Possible keys include:

=over 4

=item type

The display field type. Possible values are

=over 4

=item text

=item textarea

=item password

=item hidden

=item radio

=item checkbox

=item select

=back

=item length

The Length, in letters, to display a text or password field.

Bric::set() - Problems setting fields.

=back

B<Side Effects:> Deletes the Bric::Biz::Org::Parts::Address objects from the
Bric::Biz::Org object's internal structure, but retains a list of the IDs. These
will be used to delete the Bric::Biz::Org::Parts::Address objects from the database
when $org->save is called, then are deleted from the Bric::Biz::Org object's
internal structure. The Bric::Biz::Org::Parts::Address objects will not actually be
deleted from the database until $org->save is called.

B<Notes:> If called with a list of Bric::Biz::Org::Parts::Address object IDs,
del_address() will only delete those address object if they're associated with
the current Bric::Biz::Org object.

sub del_addr { &$get_addr_coll(shift)->del_objs(@_) }

=item $self = $org->save

Saves any changes to the Bric::Biz::Org object, including changes to associated address
(Bric::Biz::Org::Parts::Address) objects. Returns $self on success and undef on
failure.
