How to get guice to provide a unique instance with a provider?

[Maatary Okouya]

Hi, 

I have an object A that does some important loading. I use a provider for it. I have object B that needs A for its initialization. However in an object C I want to pass A, and B, properly prepared. 

Would it be possible to get a provider to return the same instance all the time, or the guice module to keep that instance provided and stop right there?

Many thanks,

I have the following on the guice website with few explanation:

  @Provides @Singleton

  TransactionLog provideTransactionLog() {

    ...

  }

Is that the solution. Does the singleton apply to the provider or the provided. If it applies to the provider then, the solution would be to retain one instance and return it each time. But that would not work with a provide method.

Any help ?

Yes, @Singleton does what you want.
