Interface Output<T>

  • All Superinterfaces:
    com.pulumi.core.internal.Copyable<Output<T>>
    public interface Output<T>
extends com.pulumi.core.internal.Copyable<Output<T>>
    Output<T> is a key part of how Pulumi tracks dependencies between Resources. Because the values of outputs are not available until resources are created, these are represented using the special Output<T> type, which internally represents two things:
    1. An eventually available value of the output
    2. The dependency on the source(s) of the output value
    In fact, Output<T> is quite similar to CompletableFuture. Additionally, they carry along dependency information.

    The output properties of all resource objects in Pulumi have type Output<T>.

    • Method Detail

      • apply

        <U> Output<U> apply​(java.util.function.Function<T,​Output<U>> func)
        Transforms the data of this Output<T> with the provided func. The result remains an Output<T> so that dependent resources can be properly tracked.

        func is not allowed to make resources.

        func can return other Output<T>s. This can be handy if you have an Output<SomeType> and you want to get a transitive dependency of it. i.e.:
        Output<SomeType> d1 = ...; Output<OtherType> d2 = d1.apply(v -> v.otherOutput); // getting an output off of 'v'.

        In this example, taking a dependency on d2 means a resource will depend on all the resources of d1. It will not depend on the resources of v.x.y.OtherDep.

        Importantly, the Resources that d2 feels like it will depend on are the same resources as d1.

        If you need have multiple Output<T>s and a single Output<T> is needed that combines both set of resources, then all(Output[]) or tuple(Output, Output, Output) should be used instead.

        This function will only be called during execution of a pulumi up request. It will not run during pulumi preview (as the values of resources are of course not known then).

        Type Parameters:
        U - type of the Output returned by func
        Parameters:
        func - the function to apply to the current value
        Returns:
        an Output after applying func

      • applyValue

        default <U> Output<U> applyValue​(java.util.function.Function<T,​U> func)
        Type Parameters:
        U - type returned by func
        Parameters:
        func - the function to apply to the current value
        Returns:
        an Output after applying func
        See Also:

        Takes in a formattableString with potential Output in the 'placeholder holes'. Conceptually, this method unwraps all the underlying values in the holes, combines them appropriately with the formattableString, and produces an Output containing the final result.

        Similarly, if any of the Outputs are secrets, then the final result will be a secret.

        Parameters:

        T5 - type of item5
        T6 - type of item6
        T7 - type of item7
        T8 - type of item8
        Parameters:
        item1 - the 1st item ot the tuple
