Class Method Details

.from_h(hash) ⇒ Content::Base

Deserialize a content object from a Hash by dispatching on the type field.

Parameters:

• hash (Hash) —

  a Hash with string keys including a “type” field

Returns:

• (Content::Base) —

  the deserialized content object

Raises:

• (InvalidItemError) —

  if the type is unknown

# File 'lib/prompt_builder/content/base.rb', line 27

def from_h(hash)
  type = hash["type"]
  class_name = TYPES[type]
  raise InvalidItemError, "Unknown content type: #{type.inspect}" unless class_name

  Content.const_get(class_name).from_h(hash)
end

Instance Method Details

#to_h ⇒ Hash

Serialize the content object to a Hash with string keys.

Returns:

• (Hash) —

  the hash representation

Raises:

• (NotImplementedError)

# File 'lib/prompt_builder/content/base.rb', line 39

def to_h
  raise NotImplementedError
