C4::Branch - Koha branch module
=head1 SYNOPSIS
use C4::Branch;
=head1 DESCRIPTION
The functions in this module deal with branches.
=head1 FUNCTIONS
=cut
@ISA = qw(Exporter);
@EXPORT = qw(
&GetBranchCategory
&GetBranchName
&GetBranch
&GetBranches
&GetBranchDetail
&get_branchinfos_of
&ModBranch
&CheckBranchCategorycode
&GetBranchInfo
&GetCategoryTypes
&GetBranchCategories
&GetBranchesInCategory
&ModBranchCategoryInfo
&DelBranch
&DelBranchCategory
);
=head2 GetBranches
$branches = &GetBranches();
returns informations about ALL branches.
Create a branch selector with the following code
IndependantBranches Insensitive...
GetBranchInfo() returns the same information without the problems of this function
(namespace collision, mainly). You should probably use that, and replace GetBranches()
with GetBranchInfo() where you see it in the code.
