I've just installed VirtualBox on my PC and installed OpenSolaris as a virtual machine within it. The PC connects to the internet via a router and uses DHCP to get its IP address. How do I configure the OpenSolaris virtual machine to use the same DHCP server so I can connect it to the net. At the... (4 Replies)

Moose::Cookbook::Basics::Immutable(3) User Contributed Perl Documentation Moose::Cookbook::Basics::Immutable(3)NAME
Moose::Cookbook::Basics::Immutable - Making Moose fast by making your class immutable
VERSION
version 2.1202
SYNOPSIS
package Point;
use Moose;
has 'x' => ( isa => 'Int', is => 'ro' );
has 'y' => ( isa => 'Int', is => 'rw' );
__PACKAGE__->meta->make_immutable;
DESCRIPTION
The Moose metaclass API provides a "make_immutable()" method. Calling this method does two things to your class. First, it makes it faster.
In particular, object construction and destruction are effectively "inlined" in your class, and no longer invoke the meta API.
Second, you can no longer make changes via the metaclass API, such as adding attributes. In practice, this won't be a problem, as you
rarely need to do this after first loading the class.
CONCLUSION
We strongly recommend you make your classes immutable. It makes your code much faster, with a small compile-time cost. This will be
especially noticeable when creating many objects.
