NAME

POE::Component::ResourcePool::Resource::TryList - Delegate to a number of resources.

SYNOPSIS

        use POE::Component::ResourcePool::Resource::TryList;

        my $good = POE::Component::ResourcePool::Resource::Good->new( ... );

        my $better = POE::Component::ResourcePool::Resource::Better->new( ... );

        my $best = POE::Component::ResourcePool::Resource::TryList->new(
                resources => [ $better, $good ],
        );

DESCRIPTION

This class allows you to specify fallback lists for resources easily.

The resources will be delegated to appropriately.

The only difference is that sometimes resources that return false from could_allocate will still have try_allocating called on them, because the try list only requires that one of the sub resources return true from could_allocate.

It is trivial to subclass and override it such that could_allocate only returns true if all the sub resources do, thus resolving this issue. However, this seems to have a diminished practical value to me.

ATTRIBUTES
