20 | =head1 SYNOPSIS
|
---|
21 |
|
---|
22 | package Foo;
|
---|
23 | require LWP::MemberMixin;
|
---|
24 | @ISA=qw(LWP::MemberMixin);
|
---|
25 |
|
---|
26 | =head1 DESCRIPTION
|
---|
27 |
|
---|
28 | A mixin class to get methods that provide easy access to member
|
---|
29 | variables in the %$self.
|
---|
30 | Ideally there should be better Perl language support for this.
|
---|
31 |
|
---|
32 | There is only one method provided:
|
---|
33 |
|
---|
34 | =over 4
|
---|
35 |
|
---|
36 | =item _elem($elem [, $val])
|
---|
37 |
|
---|
38 | Internal method to get/set the value of member variable
|
---|
39 | C<$elem>. If C<$val> is present it is used as the new value
|
---|
40 | for the member variable. If it is not present the current
|
---|
41 | value is not touched. In both cases the previous value of
|
---|
42 | the member variable is returned.
|
---|
43 |
|
---|
44 | =back
