# Zonemaster::NSArray(3pm)

Class implementing arrays that lazily looks up name server addresses from their names

## NAME

Zonemaster::NSArray - Class implementing arrays that lazily looks up name server addresses from their names

## SYNOPSIS

```
    tie @ary, 'Zonemaster::NSArray', @ns_names
```

## DESCRIPTION

This class is used for the `"glue"` and `"ns"` attributes of the Zonemaster::Zone class. It is initially seeded with a list of names, which will be expanded into proper Zonemaster::Nameserver objects on demand. Be careful with using Perl functions that act on whole arrays (particularly `"foreach"`), since they will usually force the entire array to expand, negating the use of the lazy-loading.

## METHODS

These are all methods implementing the Perl tie interface. They have no independent use.
