NAME

MooX::TaggedAttributes::Cache - Extract information from a Tagged Attribute Cache

VERSION

version 0.10

SYNOPSIS

$cache = MooX::TaggedAttributes::Cache->new( $class );

$tags = $cache->tags;

DESCRIPTION

MooX::TaggedAttributes caches attribute tags as objects of this class. The user typically never instantiates objects of MooX::TaggedAttributes::Cache. Instead, they are returned by the _tags method added to tagged classes, e.g.

$cache = $class->_tags;

CLASS METHODS

new

$cache = MooX::TaggedAttributes::Cache( $class );

Create a cache object for the $class, which must have a _tag_list method.

METHODS

tag_hash

$tags = $cache->tag_hash;

Returns a reference to a hash keyed off of the tags in the cache. The values are hashes which map attribute names to tag values.

Do Not Modify This Hash.

attr_hash

$tags = $cache->tag_hash;

Returns a reference to a hash keyed off of the attributes in the cache. The values are hashes which map tag names to tag values.

Do Not Modify This Hash.

tags

# return all of the tags as an array reference
$tags = $cache->tags;

# return the tags for the specified attribute as an array reference
$tags = $cache->tags( $attr );

Returns a reference to an array containing tags.

Do Not Modify This Array.

value

$value = $cache->value( $attr, $tag );

Return the value of a tag for the given attribute.

OVERLOAD

%{}

The object may be treated as a hash reference. It will operate on the reference returned by "tag_hash". For example,

keys %{ $cache };

is equivalent to

keys %{ $cache->tag_hash };
