Greetings,
I'm not exactly sure what its called but for example, when using
mod_perl, I
see the following:
$r->prev->uri
my $c = $r->connection;
etc..
How do you create something like this?
Easy, for instance you create an attribute "prev":
$self->{prev} = $something_that_responds_to_uri;
and then a standard getter/setter:
sub prev {
my $self = shift;
$self->{prev} = shift if @_;
$self->{prev};
}
The point is that one uses the fact that perl forgives the parens in
the getter method call:
$r->prev->uri
The "prev" in the middle is seen as a method call.
