deep_transform_keys(&block) Instance Public methods Returns a new hash with all keys converted by the block operation. This includes the keys from the root hash and from all nested hashes and arrays. hash = { person: { name: 'Rob', age: '28' } } hash.deep_transform_keys{ |key| key.to_s.upcase } # => {"PERSON"=>{"NAME"=>"Rob", "AGE"=>"28"}}

except!(*keys) Instance Public methods Replaces the hash without the given keys.

slice(*keys) Instance Public methods Slice a hash to include only the given keys. This is useful for limiting an options hash to valid keys before passing to a method: def search(criteria = {}) criteria.assert_valid_keys(:mass, :velocity, :time) end search(options.slice(:mass, :velocity, :time)) If you have an array of keys you want to limit to, you should splat them: valid_keys = [:mass, :velocity, :time] search(options.slice(*valid_keys))

printf(format, *opts) Instance Public methods Extends IO#printf to format the given opts for Kernel#sprintf using parse_printf_format

prefix() Instance Public methods BSTR prefix the prefix for the namespace applying to the node
