-
- LWP::MemberMixin - Member access mixin class
-
- =head1 SYNOPSIS
-
- package Foo;
- require LWP::MemberMixin;
- @ISA=qw(LWP::MemberMixin);
-
- =head1 DESCRIPTION
-
- A mixin class to get methods that provide easy access to member
- variables in the %$self.
- Ideally there should be better Perl language support for this.
-
- There is only one method provided:
-
- =over 4
-
- =item _elem($elem [, $val])
-
- Internal method to get/set the value of member variable
- C<$elem>. If C<$val> is present it is used as the new value
- for the member variable. If it is not present the current
- value is not touched. In both cases the previous value of
- the member variable is returned.
