Object::PadX::Role::AutoMarshal
This role adds an ADJUST sub that reads the MarshalTo attributes to try
to instantiate new objects with the listed class. It doesn't require
that the subobjects to be made with Object::Pad but it does require the
constructor to be expecting all parameters as a hash, not a hashref or
positional arguments.
CAVEATS
* This module is VERY opinionated. All constructors of sub-objects
must be expecting a hash as their only input.
* It only handles fields at object creation time. Assignment later
does not get considered, so you can overwrite the field with a
different type/class.
* IT DOES NOT CHECK TYPES. Do not use this module if you are expecting
type checking.
* It relies on experimental APIs and will likely break.
IMPORTS
use Object::PadX::Role::AutoMarshal '-toplevel';
class Foo :does(AutoMarshal) {
...
}
This is the only import right now, it creates a top level namespace role
AutoJSON for lazy people (like me). This is a bad idea, don't do it it
pollutes this globally since there is no such thing as lexical role
imports.
ATTRIBUTES
* :MarshalTo(ClassName)
Set the type of object to be instantiated during object creation.
It'll get called as "ClassName->new($field_value->%*)", expecting
the field to have been set with a hashref on the original ->new call
to your class.
* :MarshalTo([ClassName])
Create this as an array ref of ClassName objects. It'll iterate
through the field value as an array ref and call
"ClassName->new($element->%*)". All elements of the array are
expected to be hash-refs that will be dereferenced for creating the
subobjects.
* :MarshalTo({ClassName})
Create this as a hash ref of ClassName objects. It'll iterate
through the field value as an hash setting each $key and call
"ClassName->new($value->%*)" for each value. All elements of the top
level hash-ref are expected to be hash-refs that will be
dereferenced for creating the subobjects.
