Bio::Community::Role::Locked - Role for objects that can be locked (made read-only)


  package My::Package;

  use Moose;
  with 'Bio::Community::Role::Locked';

  # Use the lock() and unlock() methods as needed
  # ...



This role provides the capability to make objects of the class that consumes this role read-only. The lock() method can be invoked to make an object read-only, while unlock() restores the read/write properties of the object. If you try to call a method to modify an object that is locked or otherwise attempt to change its hash, you will get an error similar to this:

 Modification of a read-only value attempted at accessor Bio::Community::Member::foo
