def self.all
  @semantic_fields ||= Scraper.instance.get_all(SemanticField, "/category/", [
    [:code, 'td[1]/a/text()'],
    [:path, 'td[1]/a/@href'],
    [:name, 'td[2]/a/text()'],
    [:count, 'td[3]/text()']
  ])
end

.count ⇒ Integer

Counts the number of SemanticFields within Pollex

Returns:

  • (Integer) —

    number of SemanticFields in Pollex

end

.find(id) ⇒ SemanticField

Looks up SemanticField corresponding to a given internal ID

Parameters:

  • id (Integer) —

    ID of SemanticField to find

Returns:

# File 'lib/pollex/semantic_field.rb', line 45

def self.find(id)
  self.all.select { |sf| sf.id == id }[0] rescue nil
end

.find_by_name(name) ⇒ Array<SemanticField>

Note:

Pollex has no built-in search for SemanticFields, so this method is simply a filter over SemanticField.all.

Looks up all SemanticFields matching a given name.

Parameters:

  • name (String) —

    term to search for

Returns:

  • (Array<SemanticField>) —

    array of SemanticFields matching the search term
