# URI::NamespaceMap::ReservedLocalParts(3pm)

Permissible local parts for NamespaceMap

## NAME

URI::NamespaceMap::ReservedLocalParts - Permissible local parts for NamespaceMap

## VERSION

Version 1.10

## SYNOPSIS

```
    my $r = URI::NamespaceMap::ReservedLocalParts->new(disallowed => [qw/uri/]);
    say $r->is_reserved('isa'); # 1
    say $r->is_reserved('uri'); # 1
    say $r->is_reserved('foo'); # 0
```

## DESCRIPTION

URI::NamespaceMap::ReservedLocalParts is an accompanying distribution to URI::NamespaceMap. It's goal is to check for forbidden names used for local parts.

Rather than creating a blacklist that needs to be maintained, it instantiates a new Moo object, and calls `"can"` on the invocant. Using this technique, it means that every method on every Perl object (`"isa, can, VERSION"`), and Moo objects (`"BUILD, BUILDARGS"`) will be automatically black listed.

## ATTRIBUTES

URI::NamespaceMap::ReservedLocalParts implements the following attributes.

### allowed

A whitelist of local part names. Defaults to `"allowed"`, `"disallowed"` and `"is_reserved"` so that when `"can"` is called on the instance, it doesn't return a false positive for other method names associated with this package.

### disallowed

A blacklist of local part names. Does not have a default set, but usually defaults to `"uri"` when called from URI::NamespaceMap.

## METHODS

URI::NamespaceMap::ReservedLocalParts implements the following methods.

### is\_reserved

```
    my $r = URI::NamespaceMap::ReservedLocalParts->new(disallowed => [qw/uri/]);
    say $r->is_reserved('isa'); # 1
    say $r->is_reserved('uri'); # 1
    say $r->is_reserved('foo'); # 0
```

Checks if the first argument passed is reserved or not. Returns a `"boolean"`.
