Quickstart

1) Criar um container​

Você pode usar um container local, ou o singleton global via GetInjector.

uses
  Inject;

var
  Injector: TInject;
begin
  Injector := TInject.Create;
  try
    // Registros e resoluções aqui
  finally
    Injector.Free;
  end;
end;

2) Registrar serviços​

Injector.Singleton<TMinhaClasse>;
Injector.SingletonLazy<TMinhaClassePesada>;
Injector.Factory<TMinhaClasseTransient>;

3) Resolver serviços​

var S1 := Injector.Get<TMinhaClasse>;
var S2 := Injector.Get<TMinhaClasse>;

4) Registrar e resolver interfaces​

type
  IMeuServico = interface
    ['{11111111-1111-1111-1111-111111111111}']
    procedure Execute;
  end;

  TMeuServico = class(TInterfacedObject, IMeuServico)
  public
    procedure Execute;
  end;

Injector.SingletonInterface<IMeuServico, TMeuServico>;

var Svc := Injector.GetInterface<IMeuServico>;
Svc.Execute;

1) Create a container​

You can use a local container or the global singleton via GetInjector.

uses
  Inject;

var
  Injector: TInject;
begin
  Injector := TInject.Create;
  try
    // registrations and resolutions
  finally
    Injector.Free;
  end;
end;

2) Register services​

Injector.Singleton<TMyService>;
Injector.SingletonLazy<THeavyService>;
Injector.Factory<TTransientService>;

3) Resolve services​

var S1 := Injector.Get<TMyService>;
var S2 := Injector.Get<TMyService>;

4) Register and resolve interfaces​

type
  IMyService = interface
    ['{11111111-1111-1111-1111-111111111111}']
    procedure Execute;
  end;

  TMyService = class(TInterfacedObject, IMyService)
  public
    procedure Execute;
  end;

Injector.SingletonInterface<IMyService, TMyService>;

var Svc := Injector.GetInterface<IMyService>;
Svc.Execute;
