Functions ¶
func GetPowerUpFactory ¶
func GetPowerUpFactory(name string) (types.PowerUpFactory, error)
GetPowerUpFactory retrieves a power-up factory by name.
func GetTriggerFactory ¶
func GetTriggerFactory(name string) (types.TriggerFactory, error)
GetTriggerFactory retrieves a trigger factory by name.
func MustGet ¶
MustGet retrieves an item and panics if not found This is useful when the item must exist
func MustRegister ¶
MustRegister registers an item and panics if registration fails This is useful for init() functions where registration errors are programming errors
func RegisterPowerUpFactory ¶
func RegisterPowerUpFactory(name string, factory types.PowerUpFactory) error
RegisterPowerUpFactory registers a factory function for creating power-ups.
func RegisterTriggerFactory ¶
func RegisterTriggerFactory(name string, factory types.TriggerFactory) error
RegisterTriggerFactory registers a factory function for creating triggers.
Types ¶
type Registry ¶
type Registry[T any] interface { // Register adds an item to the registry Register(name string, item T) error // Get retrieves an item from the registry Get(name string) (T, error) // Remove removes an item from the registry Remove(name string) error // List returns all registered names List() []string // Has checks if an item is registered Has(name string) bool // Clear removes all items from the registry Clear() // Count returns the number of registered items Count() int }
Registry is a generic, thread-safe registry for storing and retrieving items by name
Example ¶
Example usage
// Create a registry for string handlers
reg := New[func() string]()
// Register some handlers
_ = reg.Register("greeting", func() string { return "Hello, World!" })
_ = reg.Register("farewell", func() string { return "Goodbye!" })
// List all registered handlers
names := reg.List()
sort.Strings(names)
fmt.Println("Registered handlers:", names)
// Get and execute a handler
if handler, err := reg.Get("greeting"); err == nil {
fmt.Println(handler())
}
Output: Registered handlers: [farewell greeting] Hello, World!
func GetRegistry ¶
GetRegistry returns the global registry for the specified type. It uses a type switch to return the correct singleton instance.
