NAME

Elastic::Model::Meta::Class::Model - A meta-class for Models

VERSION

version 0.52

DESCRIPTION

Holds static information about your model: namespaces and their types, and char_filters, tokenizers, filters and analyzers for analysis.

You shouldn't need to use this class directly. Everything you need should be accessible via Elastic::Model or Elastic::Model::Role::Model.

METHODS

is_default()

$bool = $meta->is_default($type => $name);

Returns true if $name is a $type (analyzer, tokenizer, filter, char_filter) available in Elasticsearch by default.

Default analyzers

standard, simple, whitespace, stop, keyword, pattern, snowball, and the language analyzers: arabic, armenian, basque, brazilian, bulgarian, catalan, chinese, cjk, czech, danish, dutch, english, finnish, french, galician, german, greek, hindi, hungarian, indonesian, italian, latvian, norwegian, persian, portuguese, romanian, russian, spanish, swedish, thai, turkish

Default tokenizers

edge_ngram, keyword, letter, lowercase, ngram, path_hierarchy, pattern, standard, uax_url_email, whitespace

Default token filters

asciifolding, dictionary_decompounder, edge_ngram, elision, hyphenation_decompounder, icu_collation, icu_folding, icu_normalizer, kstem, length, lowercase, ngram, pattern_replace, phonetic, porterStem, reverse, shingle, snowball, standard, stop, synonym, trim, truncate, unique, word_delimiter

Default character filters

html_strip, mapping

analysis_for_mappings()

$analysis = $meta->analysis_for_mappings($mappings)

Used to generate the analysis settings for an index, based on which analyzers are used in the mappings for all types in the index.

wrapped_class_name()

$new_class = $meta->wrapped_class_name($old_class);

Generates a semi-anonymous classname with the format Elastic::Model::__WRAPPED_::$n

ATTRIBUTES

namespaces

\%namespaces    = $meta->namespaces;
\%namespace     = $meta->namespace($name);
$bool           = $meta->has_namespace($name);
@names          = $meta->all_namespaces;

A hash ref containing all namespaces plus their configuration, eg:

{
    myapp => {
        types => {
            user => 'MyApp::User'
        }
    }
}

unique_index

$index = $meta->unique_index

The name of the index where unique keys will be stored, which defaults to unique_key. A different value can be specified with has_unique_index.

See Elastic::Manual::Attributes::Unique for more.

analyzers

\%analyzers     = $meta->analyzers;
\%analyzer      = $meta->analyzer($name);
$bool           = $meta->has_analyzer($name);
@names          = $meta->all_analyzers;

A hash ref containing all analyzers plus their configuration, eg:

{
    my_analyzer => {
        type        => 'custom',
        tokenizer   => 'standard',
        filter      => ['lower']
    }
}

tokenizers

\%tokenizers    = $meta->tokenizers;
\%tokenizer     = $meta->tokenizer($name);
$bool           = $meta->has_tokenizer($name);
@names          = $meta->all_tokenizers;

A hash ref containing all tokenizers plus their configuration, eg:

{
    my_tokenizer => {
        type    => 'pattern',
        pattern => '\W'
    }
}

filters

\%filters       = $meta->filters;
\%filter        = $meta->filter($name);
$bool           = $meta->has_filter($name);
@names          = $meta->all_filters;

A hash ref containing all filters plus their configuration, eg:

{
    my_filter => {
        type        => 'edge_ngram',
        min_gram    => 1,
        max_gram    => 20
    }
}

char_filters

\%char_filters  = $meta->char_filters;
\%char_filter   = $meta->char_filter($name);
$bool           = $meta->has_char_filter($name);
@names          = $meta->all_char_filters;

A hash ref containing all char_filters plus their configuration, eg:

{
    my_char_filter => {
        type        => 'mapping',
        mappings    => ['ph=>f','qu=>q']
    }
}
