NAME
DustyDB::Meta::Attribute - Moose meta-class for DustyDB::Record attributes
VERSION
version 0.06
DESCRIPTION
For any model class (one that uses DustyDB::Object and does DustyDB::Record), all the attributes will be given this Moose meta-class role. These attributes are used to help with encoding and decoding types that might not be easily stored directly within DBM::Deep.
ATTRIBUTES
encode
This is a subroutine used to transform a Perl object into a something else you want to store. Since we use DBM::Deep to store the objects, this can be much more flexible than just a scalar.
Be careful, though, not to store a hash with a class_name
key or very bad things might happen.
This subroutine should expect the decoded value in $_
and return whatever value should be stored.
decode
This is a subroutine used to transform the previously encoded and stored "thing" into the object that is stored in the column.
This subroutine should expect the encoded value in $_
and return whatever value should be loaded into the model attribute.
METHODS
perform_encode
This is a helper method to make sure that encoding is performed properly.
perform_decode
This is a helper method to make sure that decoding is performed properly.
