Specio::Constraint::ObjectIsa - A class for constraints which require an object that inherits from a specific class
version 0.37
my $type = Specio::Constraint::ObjectIsa->new(...); print $type->class;
This is a specialized type constraint class for types which require an object that inherits from a specific class.
This class provides all of the same methods as Specio::Constraint::Simple, with a few differences:
The parent parameter is ignored if it passed, as it is always set to the Defined type.
parent
Defined
The inline_generator and constraint parameters are also ignored. This class provides its own default inline generator subroutine reference.
inline_generator
constraint
This class overrides the message_generator default if none is provided.
message_generator
Finally, this class requires an additional parameter, class. This must be a single class name.
class
Returns the class name passed to the constructor.
This class does the Specio::Constraint::Role::IsaType, Specio::Constraint::Role::Interface, and Specio::Role::Inlinable roles.
