NAME
MooX::Role::CloneSet - create updated copies of immutable objects
SYNOPSIS
DESCRIPTION
MooX::Role::CloneSet
is a role for immutable objects, providing an easy way to create a new object with some modified properties. It provides the cset()
method that creates a new object with the specified changes, shallowly copying all the rest of the original object's properties.
METHODS
cset(field => value, ...)
Shallowly clone the object, making the specified changes to its attributes.
Note that this method obtains the names and values of the current attributes by dereferencing the object as a hash reference; since Moo does not provide metaclasses by default, it cannot really get to them in any other way. This will not work for parameters that declare an
init_arg
; seeMooX::Role::CloneSet::BuildArgs
for an alternative if using truly immutable objects.
