Returns a new hash with all keys downcased and converted to symbols.

Returns:

def normalize_keys
  transform_keys { |key| key.downcase.to_sym rescue key }
end

#recursively_normalize_keys ⇒ Hash

Returns a new Hash, recursively downcasing and converting all keys to symbols.

Returns:

def recursively_normalize_keys
  recursively_transform_keys { |key| key.downcase.to_sym rescue key }
end

#recursively_transform_keys(&block) ⇒ Hash

Returns a new hash, recursively converting all keys by the block operation.

Returns:

# File 'lib/delphix/utils.rb', line 94

def recursively_transform_keys(&block)
  _recursively_transform_keys_in_object(self, &block)
end

#transform_keys ⇒ Hash

Returns a new hash with all keys converted using the block operation.

Examples:

hash = { name: 'Tigie', age: '15' }
hash.transform_keys{ |key| key.to_s.upcase }
  # => { "AGE" => "15", "NAME" => "Tigie" }
