VERSION
version 0.46DESCRIPTION
This is a decorator object that contains an underlying type constraint. We use this to control access to the type constraint and to add some features.METHODS
This class defines the following methods.new
Old school instantiation__type_constraint ($type_constraint)
Set/Get the type_constraint.isa
handle "$self->isa" since "AUTOLOAD" can't - this tries both the type constraint, and for a class type, the class.can
handle $self->can since AUTOLOAD can't._throw_error
properly delegate error messagesDESTROY
We might need it laterAUTOLOAD
Delegate to the decorator target, unless this is a class type, in which case it will try to delegate to the type object, then if that fails try the class. The method 'new' is special cased to only be permitted on the class; if there is no class, or it does not provide a new method, an exception will be thrown.AUTHOR
