=head1 NAME
|
|
|
|
C4::Category - objects from the categories table
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
use C4::Category;
|
|
my @categories = C4::Category->all;
|
|
print join("\n", map { $_->description } @categories), "\n";
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
Objects of this class represent a row in the C<categories> table.
|
|
|
|
Currently, the bare minimum for using this as a read-only data source has
|
|
been implemented. The API was designed to make it easy to transition to
|
|
an ORM later on.

=head3 C4::Category->new(\%opts)
|
|
|
|
Given a hashref, a new (in-memory) C4::Category object will be instantiated.
|
|
The database is not touched.
