Package org.incendo.cloud.injection

Interface ParameterInjector<C,T>

Type Parameters:
C - command sender type
T - Type of the value that is injected by this injector
All Known Implementing Classes:
ParameterInjector.ConstantInjector
Functional Interface:
This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
@FunctionalInterface @API(status=STABLE) public interface ParameterInjector<C,T>
Injector that injects parameters into Command annotated methods

  • Method Details

    • constantInjector

      @API(status=STABLE) static <C, T> @NonNull ParameterInjector<C,T> constantInjector(@NonNull T value)
      Returns a parameter injector that always injects value.
      Type Parameters:
      C - command sender type
      T - type of the value
      Parameters:
      value - value to inject
      Returns:
      the injector

    • create

      @Nullable T create(@NonNull CommandContext<C> context, @NonNull AnnotationAccessor annotationAccessor)
      Attempts to create a value that should then be injected into the Command annotated method.

      If the injector cannot (or shouldn't) create a value, it is free to return null.

      Parameters:
      context - command context that is requesting the injection
      annotationAccessor - annotation accessor proxying the method and parameter which the value is being injected into
      Returns:
      the value if it could be created, else null in which case no value will be injected by this particular injector
