interface

问题 I am struggling with explicit interfaces in Fortran. In one instance, the compiler has requested that I write an explicit interface when I attempt to use an assumed-shape array as a dummy argument for a function or subroutine (i.e., procedure): Explicit interface required for ... assumed-shape argument . For example, this would appear like REAL, INTENT(IN OUT) :: dummy_array(:) in a subroutine. The (:) in the declaration of the array means that the compiler takes care of passing information

问题 I have a function that takes a few parameters and generates objects that will be passed into an external process. Sine I have no control over the shapes that need to be ultimately created, I have to be able to take some varying parameters to my function and assemble them into the appropriate objects. Here's a really basic example that exhibits the issue I'm having: interface T1A { type: 'type1'; index: number; } interface T1B { type: 'type1'; name: string; } interface T2A { type: 'type2';

问题 It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center. Closed 8 years ago . I have two classes that need to extend one class. I am getting a compiler error since this cannot happen in Java. I know that you can implement as many interfaces you want to in Java but can only extend one other

问题 In Golang, after asserting to a slice, how is one able to remove an element from said slice? For example, the following returns the error cannot assign to value.([]interface {}) value.([]interface{}) = append(value.([]interface{})[:i],value.([]interface{})[i+1:]...) 回答1: If you have a slice value wrapped in an interface, you can't change it. You can't change any value wrapped in interfaces. When an interface value is created to wrap a value, a copy is made and stored in the interface. When

问题 I know that there are similar questions on StackOverflow but I've tried all of them and none of them worked. On my laptop, I have an Apache server, a website built with PHP and a Python script. Attempts: 1) system $mystring = system('python myscript.py myargs', $retval); 2) and 3) JSON and $temp = exec($command, $output); php: #first case command= 'C:\wamp\www\com\non.py file'; $temp = exec($command, $output); echo(" output "); echo $output; echo " hello "; echo $temp; #second case // Execute

问题 I'm typing up a localization-library, and I'm aiming to have it strongly typed (as it will be re-used in multiple angular-applications) and - at the same time - backwards compatible so that we won't have to re-write all existing localization-files. However, the structure of said localization-files is causing me a bit of a headache. Per example: { 'any-random-key': 'This is a string', 'another-random-key': { 'random-key': 'This is a string' }, 'yet-another-random-key': { 'random-key-2': 'This
