overriding

问题 Overriding Woocommerce files from my child theme is not working at all. I am sure everything is 100% right, really frustrating. I am following every step in a video at this page: https://docs.woocommerce.com/document/template-structure/ 回答1: Ah, it was so simple. Go to this path: WP Dashboard -> WooCommerce -> System Status -> Tools and then uncheck the "Template debug mode": 回答2: If someone is still interested in this topic I have found what was causing this issue on my theme. Just add the

问题 To give you some context, yesterday I came across this post. I found the problem quite interesting, so I tried to find a solution that would keep the syntax as close as possible to what was asked. Here is what I came up with: class DummyCube: cubes = [] @classmethod def __getattribute__(cls, name): print('is this called?') attributes = [getattr(cube, name) for cube in cls.cubes] return attributes class Cube: def __init__(self, volume): DummyCube.cubes.append(self) self.volume = volume a =

问题 I'm trying to introduce Kotlin into my current project. I've decided to begin with entities, which seem to map perfectly to data classes. For example I have a data class: data class Video(val id: Long, val ownerId: Long, val title: String, val description: String? = null, val imgLink: String? = null, val created: Date? = null, val accessKey: String? = null, val views: Long? = null, val comments: Long? = null, val videoLink: String? = null): Entity Which implements Java interface: public

问题 For example: class Base { virtual void my_function() = 0; }; class Derived : Base { void my_function() override; }; From what I read, the override keyword is used to make sure that we have the correct signature in the function that we are overriding, and it seems to be its only use. However, in the case of a pure virtual function, the compiler would throw an error if we used an incorrect signature in the Derived class (or Base class, depending on how one see things). So, is there any point in

问题 I'm trying to change the background color of the menuitem popover. But I am unable to remove paddingtop and paddingBottom from menuitem. It's kind of annoying because some materialui components inherit styles from paper, list, menu and etc. Is there a clean and efficient way to work around this? For eg, using overrides in theme and etc. I have experiment and I know it can be done using inline styles/classes but i do not wish to use that method. I've tried using ListProps={{disablePadding:

问题 Basis: I want to write a procedure which make some operation for any input array type: integer, real(4), real(8) , etc. The only idea i read on StackOverflow is to imitate C++ templates, using generic procedures for overriding and preprocessor for including duplicating code. But searching for API of popular I/O software, i found this in manual: function nf90_put_var(ncid, varid, values, start, count, stride, map) integer, intent(in) :: ncid, varid any valid type, scalar or array of any rank,

问题 I override both the hashCode() and equals(), but I don't modify anything inside the overridden methods . @Override public int hashCode() { int hash = 7; hash = 67 * hash + Objects.hashCode(this.model); hash = 67 * hash + this.year; return hash; } @Override public boolean equals(Object obj) { if (obj == null) { return false; } if (getClass() != obj.getClass()) { return false; } final PC other = (PC) obj; if (!Objects.equals(this.model, other.model)) { return false; } if (this.year != other

问题 I am doing some experimentation with C++. I've been imporessioned by some behaviours with polymorphism. In other languages (such as c#), when I assign an object based on a derived class to an object of BaseType: this object starts working with the derived class code. Or If I have a list of BaseType objects and I put derived class based objects in it: every element works according to the specific Type. In c++ no... I obtained this behaiviour in C++ just using pointers. Is there an alternative
