DESCRIPTION

MooseX::AttributeFilter is a port of MooX::AttributeFilter to Moose.

A filter a method that is called before an attribute value is set (by accessor or constructor). It is called before coercions, type checks, and triggers.

It is called as a method (so receives the object) with the new attribute value as its first parameter, and the old attribute value as the second parameter. (When called from constructor, no old value, so only one parameter.) Its return value is used as the attribute value.

It is even called when an attribute value is build by builder methods or defaults.

See MooX::AttributeFilter for more details and for use cases.

BUGS

Some parts don't work correctly in mutable classes. Mutable classes are slow anyway.
