JAX-RS writer interceptor works for every response even with NameBinding

假如想象 提交于 2020-03-03 13:00:14
问题 I need to intercept a response from the server that was generated for a specific API call and change it. I used the JAX-RS 'WriterInterceptor' for this and I have created a NameBinding as well. But the server is intercepting every response out from the server. What am I doing wrong here? Shown below is the code I have tried. Why is the name binding does not work? (I have verified that when calling other API resources the particular method that I have use name binding is not called.) Name

Python; name bindings are not object references?

问题 I am trying to understand what exactly a Python name binding is, and when this binding is interpreted. In c, include <stdio.h> int main() { int X = 42; int* Y[1]; Y[0] = &X; X = 666; printf("%d", *Y[0]); return 0; } prints 666. I was expecting the block of Python code: X = 42 L = [] L.append(X) #3 X = 666 print(L) #5 to do the same, but it does not. What exactly happens between the lines labeled 3 and 5? Does #3 make another reference to the object known as "42", like X, lets call it X', and

问题 Need help with understanding the following sentence from PEP 227 and the Python Language Reference If a variable is referenced in an enclosed scope, it is an error to delete the name. The compiler will raise a SyntaxError for 'del name'. Lack of examples caused I couldn't reproduce an error at compile time, so an explanation with examples is highly desirable. 回答1: The following raises the execption: def foo(): spam = 'eggs' def bar(): print spam del spam because the spam variable is being

point of instantiation and name binding

I am confused about the point of instantiation with the following example: #include <iostream> void f(int){std::cout<<"int"<<std::endl;}//3 template <typename T> void g(T t) { f(t);//4 } void f(double){std::cout<<"double"<<std::endl;} int main() { g<int>(1);//1.point of instantiation for g<int> g<double>(1.1);//2.point of instantiation for g<double>, so f(double) is visible from here? return 0; } I though f is a dependent name and 1. is the point of instantiation for g< int > and 2. is the point of instantiation for g< double >, so f(double) is visible for g(1.1), however the output is int int

What happens when JavaScript variable name and function name is the same?

I have the following code, where I declare a function and after it, a variable with the same name as the function: function a(x) { return x * 2; } var a; alert(a); I expected this to alert undefined , but if I run it, the alert will display the following: function a(x) { return x * 2 } If I assign a value to the variable (like var a = 4 ), the alert will display that value ( 4 ), but without this change a will be recognized as a function. Why is this happening? Functions are a type of object which are a type of value . Values can be stored in variables (and properties, and passed as arguments
