Error::Hierarchy::Container - Container for hierarchical exceptions
my $my_exception = create_some_exception();
my %exception_args = (foo => 'bar');
my $uuid1 = gen_some_uuid();
my $uuid2 = gen_some_uuid();
my $container = Error::Hierarchy::Container->new;
This class implements a container for hierarchical exception objects. It is effectively a Data::Container but also has the following methods.
Takes an exception class name (a string) and a hash of arguments. First the exception is constructed with the given arguments, then it is added - using items_set_push() - to the container. It's really a shortcut that saves you from having to record the exception and then adding it to the container yourself.
Takes a list of uuid values and deletes all those exceptions from the container whose uuid appears in the given list.
Deletes duplicate exceptions. Two exceptions are considered to be the same if they are of the same class and have the same properties, as defined by the exception's properties_as_hash() method.
Overrides Data::Container's items_push() method by calling the before_push trigger before pushing. The list of items to be pushed is passed to the trigger. One possible use might be to warn if you try to push any items that are not derived from Error::Hierarchy. The trigger mechanism is based on Class::Trigger.
Similar to items_push().
