c # – In Moq, lambda cannot be verified as a parameter

Functional Code:

_MyObj.MyMethod(l =>
                    {
                        l.Content.Headers.ContentType = new MediaTypeHeaderValue("json");                
                    }).Returns(value);

Test code:

_MyObj.Setup(m => m.MyMethod(
                It.IsAny>()).
                Callback>
                ((message) => saveObject = message).Return(value);

Using MOQ is there any way to verify that ContentType was established in new MediaTypeHeaderValue("json")? I can't seem to inspect saveOject.Content.Headers.ContentType as (psudeocode) Assert.AreEqual(saveObject.Content.Headers.ContentType, new MediaTypeHeaderValue("json")). saveObject It only has methods / properties like Invoke () available for my inspection.

Thank you!

lambda calculation – Reduction of the normal order – is the left-most order the left-most order just left?

This is a quick question. I have been reading about Lambda's calculation, and I see the normal order as "the outermost leftmost first," and the application order described as "the leftmost leftmost."

I think This makes sense to me, but I just want to make sure I understand. Is it the case that the first application in normal order will always be the leftmost lambda symbol within the lambda chain? (This assumes that there is something to apply to this lambda. If not, we would simply move on to the next one, from left to right).

c # – I have a problem with the test the lambda function after loading the zip file

Hi, I'm trying to execute the lambda function after successfully compiling and loading the lambda zip.

It is giving me an error like:
enter the description of the image here

What I get is the following:
{
"errorType": "LambdaException",
"ErrorMessage": "Could not find the assembly of the specified controller with the filename & # 39; LambdaTest, Culture = neutral, PublicKeyToken = null & # 39 ;. The assembly must be located in the root of the .zip file loaded".
}

How to find a lambda term to complete a function?

I tried to complete this exercise but I stopped …
Defining a $ lambda $-term M such that:
$$ () : simeq _ { beta} : $$

I chose $ M = lambda m lambda a lambda b lambda p , ((p) m) b : $ so I have to find a representation T of a function using M that value true if the sequence is empty and false if it is not A sequence is defined as:
$$ () = lambda x_0 lambda x_1 lambda z z \
(b) = lambda x_0 lambda x_1 lambda z (z) x_b \ (b_1 b_2) = lambda x_0 lambda x_1 lambda z ((z) x_ {b_1}) x_ {b_2} \
. \.
\.
\ (b_1 .. b_n) = lambda x_0 lambda x_1 lambda z (… ((z) x_ {b_1}) x_ {b_2} …) x_ {b_n} $$

So the exercise sequence is:
$$ (01101) = lambda x_0 lambda x_1 lambda z (((((z) x_0) x_1) x_1) x_0) x_1 $$
For example, T must be:
$ (T) (01101) simeq { beta} $ false While $ (T) () simeq { beta} $ true.
It really seems difficult. How can I do that?

python: allow the lambda call function through the use of the operator

I was thinking of a decorator that allows you to call a lambda function through an operation instruction, in this example, the @ one.

How about this:

def at(l):
    class At:
        def __rmatmul__(self, arg):
            return l(arg)

    return At()

Here is an executable example in Python Anywere

amazon web services – AWS Amplify – Pipeline Resolvers vs Lambda Resolvers

When you need to access multiple resources (e.g., Different DynamoDB tables) from a single custom gql operation with AWS Amplify, why would you use pipeline solvers on lambda solvers and vice versa? When reading, it seems that there is very little information about the advantages / disadvantages of each approach, as well as the use cases in which one could be better than the other.

I've read that debugging pipeline solvers is a nightmare because you can't print / console.log, so if that's true, that's a big drawback of pipeline solvers and a reason to use lambdas instead …

C ++ callback with lambda function

I am trying to pass a generic callback to a function and then call member functions of different objects within that callback. In this case, I am creating a closure with a lambda function to capture the objects and then within the lambda I am calling member functions.

Well, for example, the code is something like this:

#include 
#include 
#include  


class SomeClass
{

public:
    void someFunction() {
        std::cout << "Printing from SomeClass" << std::endl;
    }

};


class AnotherClass
{

public:
    void anotherFunction() {
        std::cout << "Printing from AnotherClass" << std::endl;
    }

};


void functionWithCallback(std::function callback)
{
    // Do some stuff ...

    callback();
}


int main() 
{
    SomeClass some_object = SomeClass();
    AnotherClass another_object = AnotherClass();

    std::function callback = (&some_object, &another_object)() {
        some_object.someFunction();
        another_object.anotherFunction();
    };

    functionWithCallback(callback);
}

My question is: is this the right way? Is there any more elegant way to do this?

c # – Cannot convert lambda expression to type 'Delegate' because it is not a delegate type

using (Linq) DataSet – I group and totalize it from one datatable to another, but I just want to grab a feature of an element as if adding, or anything but this error appears to me the code where I get an error is

DataRow row2 = dt.NewRow();
   row2("Nombre") = item.Key;
row2("pesoCOMPO") = item.Sum(x => Convert.ToInt32(x("pesoCOMPO")));
row2("CantidadoCOMPO") = item.Sum(x => Convert.ToInt32(x("CantidadoCOMPO")));
row2("Tipo") = item.First(x => x("Tipo").ToString());

type theory: in the lambda calculation with products and sums is $ f: [n] to [n]$ beta eta $ equivalent to $ f ^ n!

$ eta $-reduction is often described as the emergence of the desire for functions that are punctually equal to be syntactically equal. In a calculation simply typed with products is enough, but when it comes to sums, I don't see how to reduce the functions of equal points to a common term.

For example, it is easy to verify that any function $ f: (1 + 1) a (1 + 1) $ is punctual equal to $ lambda x.f (fx) $or more generally $ f $ is punctual equal to $ f ^ n!} when $ f: A a A $ Y $ A $ has exactly $ n $ inhabitants is it possible to reduce $ f ^ n!} to $ f $? If not, is there an extension of the simply typed calculation that allows this reduction?

AWS Lambda + SOAP + Self Signed Certs

I want to implement a client for a SOAP application that requires a series of digital certificates to access the API.

I plan to develop it in Java with JAX-RS since it facilitates the implementation of the function in AWS, (As I have read).
But I'm not sure if I can validate the certificates from the lambda, since I also read that API Gateway is not compatible with SOAP.
Anyone know what is the best way to do this development.

Thank you.
