Mite will co-operate with Sub::HandlesVia to implement \f(CW\*(C`handles_via\*(C'\fR and avoid your project having a Sub::HandlesVia dependency! .SS "Which Methods Can Be Delegated To?" .IX Subsection "Which Methods Can Be Delegated To?" The \f(CW\*(C`handles_via\*(C'\fR option indicates which library of methods should be available. Valid values include Array, Blessed, Bool, Code, Counter, Enum, Hash, Number, Scalar, and String. .PP An arrayref can be provided for \f(CW\*(C`handles_via\*(C'\fR, though many of the options are conceptually contradictory. .PP .Vb 1 \& handles_via => [ \*(AqNumber\*(Aq, \*(AqScalar\*(Aq ] .Ve .ie n .SS """use Sub::HandlesVia""" .el .SS "\f(CWuse Sub::HandlesVia\fP" .IX Subsection "use Sub::HandlesVia" Mite goes to a lot of effort to avoid you needing to \f(CW\*(C`use Sub::HandlesVia\*(C'\fR directly in your classes and roles, and thus avoid you needing to add it as a dependency. .PP However, there are edge cases that it might not handle. In these cases, you should be able to \f(CW\*(C`use SubHandlesVia\*(C'\fR in your code \fIafter\fR your \&\f(CW\*(C`use MyApp::Mite\*(C'\fR and Sub::HandlesVia will intervene and make things work. This adds a dependency on Sub::HandlesVia though. .PP .Vb 3 \& package MyApp::Kitchen { \& use MyApp::Mite; \& use Sub::HandlesVia; \& \& has food => ( \& is => \*(Aqro\*(Aq, \& isa => \*(AqArrayRef[Str]\*(Aq, \& handles_via => \*(AqArray\*(Aq, \& default => sub { [] }, \& handles => { \& \*(Aqadd_food\*(Aq => \*(Aqpush\*(Aq, \& \*(Aqfind_food\*(Aq => \*(Aqgrep\*(Aq, \& }, \& ); \& } .Ve .PP Now Mite will no longer generate \f(CW\*(C`add_food\*(C'\fR and \f(CW\*(C`find_food\*(C'\fR methods in your \&\fIKitchen.pm.mite.pm\fR file when you run \f(CW\*(C`mite compile\*(C'\fR.
