note stvn <BLOCKQUOTE><I> How do I set read-only variables in BUILD? </I></BLOCKQUOTE> <P> Why not just make a private writer, like this <CODE> has 'foo' => ( is => 'ro', isa => 'Something', writer => '_set_foo', lazy => 1, build => '_build_foo', ); </CODE> </P> <BLOCKQUOTE><I> Which is called first, BUILD or the attribute_builders? </I></BLOCKQUOTE> <P> The entire object instance is created and finalized before BUILD is called. When it gets to BUILD you can be sure you have a complete object (minus any non-initialized lazy attrs, etc). </P> <div class="pmsig"><div class="pmsig-315586"> -stvn </div></div> 877225 877225
