=head1 NAME
|
|
|
|
Bugzilla::WebService::Util - Utility functions used inside of the WebService
|
|
code. These are B<not> functions that can be called via the WebService.
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
This is somewhat like L<Bugzilla::Util>, but these functions are only used
|
|
internally in the WebService code.
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
filter({ include_fields => ['id', 'name'],
|
|
exclude_fields => ['name'] }, $hash);
|
|
|
|
validate(@_, 'ids');
|
|
|
|
=head1 METHODS
|
|
|
|
=over
|
|
|
|
=item C<filter_fields>
|
|
|
|
This helps implement the C<include_fields> and C<exclude_fields> arguments
|
|
of WebService methods. Given a hash (the second argument to this subroutine),
|
|
this will remove any keys that are I<not> in C<include_fields> and then remove
|
|
any keys that I<are> in C<exclude_fields>.
|
|
|
|
=item C<validate>
|
|
|
|
This helps in the validation of parameters passed into the WebSerice
|
|
methods. Currently it converts listed parameters into an array reference
|
|
if the client only passed a single scalar value. It modifies the parameters
|
|
hash in place so other parameters should be unaltered.
