NAME ^

AnyEvent::Subprocess::Role::WithDelegates - paramaterized role consumed by classes that have delegates

VERSION ^

DESCRIPTION ^

This role gives its consuming class the ability to have typed delegates. The type of the delegate is provide at application time via the type parameter.

Once applied, you get:

INITARGS ^

delegates

A list (arrayref) of delegates. A delegate can be an instance of a AnyEvent::Subprocess::Delegate class, a string (which will be resolved via AnyEvent::Subprocess::Role::WithDelegates::Manager, or a two-element hashref or arrayref of the delegate name and a hashref of delegate args. [ Name => { args } ] or { Name => { args } }. Name is treated like a string above, and the args are handled by the delegate's constructor or by the method supplied at delegate registration time. See AnyEvent::Subprocess::Role::WithDelegates::Manager for details.

METHODS ^

delegate($name)

Return the delegate named $name. Dies if there is no delegate by that name.

(This method is called by users of AnyEvent::Subprocess.)

_invoke_delegates($method, @args)

Invokes $delegate->$method($self, @args) on each delegate (in the order they were passed to the constructor). Returns a list of the return values of each delegate.

(This method is usually called internally by AnyEvent::Subprocess, not by end-users.)
