JSON::RPC::Legacy::Procedure - JSON-RPC Service attributes
=head1 SYNOPSIS
package MyApp;
use base ('JSON::RPC::Legacy::Procedure');
sub sum : Public {
my ($s, @arg) = @_;
return $arg[0] + $arg[1];
}
# or
sub sum : Public(a, b) {
my ($s, $obj) = @_;
return $obj->{a} + $obj->{b};
}
# or
sub sum : Number(a:num, b:num) {
my ($s, $obj) = @_;
return $obj->{a} + $obj->{b};
}
# private method can't be called by clients
sub _foobar : Private {
# ...
}
