VERSION

version 0.32

SUBROUTINES

parse_pars

( $mpars, $ipars, $spars ) = parse_params( \%args  );

Returns the model interface signal parameters from %args.

can_meth

$code = can_meth( $obj, @method, ?\%pars );

Scans an object to see if it provides one of the specified methods. For each $method in @methods, it probes for __$method__, then $method.

By default, it returns a reference to the first method it finds, otherwise undef if none was found.

The return value can be altered using %pars.

name

return the name of the method.

code

return the coderef of the method. (Default)

If both code and name are specified, both are returned as a list, name first:

($name, $code ) = can_meth( $obj, @methods, {name => 1, code => 1 } );

resolve_meth

$code = resolve_meth( $target, $method, @fallbacks );

Return a coderef to the specified method or one of the fallbacks.

If $method is a coderef, it is returned.

If $method is defined and is not a coderef, it is checked for directly via $target-can>. If it does not exist, a Iterator::Flex::Failure::parameter error is thrown.

If $method is not defined, then can_meth( $target, @fallbacks ) is returned.

load_module

$module = load_module( $module, ?\@namespaces );

Loads the named module. If $module begins with a + it is assumed to be a fully qualified module name, otherwise it is searched for in the namespaces provided by @namespaces (which defaults to the namespaces returned by the _namespaces class method).

Throws Iterator::Flex::Failure::class if it couldn't require the module (for whatever reason).

load_role

$module = load_role( $role, @namespaces );

Loads the named role. If $role begins with a +, it is assumed to be a fully qualified name, otherwise it is searched for in the @namespaces
