Class InstanceFactory<T>

  • All Implemented Interfaces:
    Factory<T>, Lazy<T>, jakarta.inject.Provider<T>
    public final class InstanceFactory<T>
extends java.lang.Object
implements Factory<T>, Lazy<T>
    A Factory implementation that returns a single instance for all invocations of get().

    Note that while this is a Factory implementation, and thus unscoped, each call to get() will always return the same instance. As such, any scoping applied to this factory is redundant and unnecessary. However, using this with DoubleCheck#provider is valid and may be desired for testing or contractual guarantees.
