Functions ¶
func ClearRegistry ¶
func ClearRegistry()
func MarshalPolymorphicJSON ¶
func MarshalPolymorphicJSON(obj Polymorphic) ([]byte, error)
Marshal an object with a discriminator
func Register ¶
func Register[T Polymorphic](factory func() T)
func RegisterType ¶
func RegisterType[T any]()
func RegisterWithDiscriminator ¶
func RegisterWithDiscriminator(discriminator string, factory TypeFactory)
Register stores a factory function with its discriminator.
Types ¶
type Envelope ¶
Envelope holds type info and raw JSON data
func NewEnvelope ¶
func NewEnvelope(obj Polymorphic) *Envelope
Create a new Envelope with a discriminator and content
func (*Envelope) MarshalJSON ¶
Implements json.Marshaler
func (*Envelope) UnmarshalJSON ¶
Implements json.Unmarshaler UnmarshalJSON is a custom JSON unmarshaler for the Envelope type. It extracts the raw JSON data into a map and looks for a discriminator field named "$type" to determine the concrete type of the content. The content is then unmarshaled into the appropriate type using a factory function registered for the discriminator. If any required fields are missing or if unmarshaling fails, an error is returned.
Parameters: - data: The JSON-encoded data to be unmarshaled.
Returns: - error: An error if unmarshaling fails or if required fields are missing.
type Polymorphic ¶
type Polymorphic interface {
GetDiscriminator() string
}
Polymorphic ensures types implement GetDiscriminator().
func CreateInstance ¶
func CreateInstance(discriminator string) (Polymorphic, error)
CreateInstance creates an instance based on the discriminator.
type TypeFactory ¶
type TypeFactory = func() any
TypeFactory creates instances of registered types.
func LoadFactory ¶
func LoadFactory(discriminator string) (TypeFactory, error)
