backwards-compatibility

问题 How can I achieve something like this: <xs:element name="getSubjectProductsResponse"> <xs:complexType> <xs:sequence minOccurs="0" maxOccurs="unbounded"> <xs:element name="Products"> <xs:complexType> <xs:sequence> <xs:element name="Date" type="xs:date"/> <xs:element name="Branch" type="xs:date" minOccurs="0"/> <xs:element name="State" type="xs:string"> <xs:element name="ProductDetail"> <xs:complexType> **<xs:choice> <xs:element name="Account" type="ns:TAccount"/> <xs:element name="KK" type="ns

问题 I'm migrating a C++ Visual Studio Project from VS2017 to VS2019. I'm getting an error now, that didn't occur before, that can be reproduced with these few lines of code: struct Foo { Foo() = default; int bar; }; auto test = Foo { 0 }; The error is (6): error C2440: 'initializing': cannot convert from 'initializer list' to 'Foo' (6): note: No constructor could take the source type, or constructor overload resolution was ambiguous The project is compiled with /std:c++latest flag. I reproduced

问题 I have MASM synchronizing code for an application which runs on both Intel and AMD x86 machines. I'd like to enhance it using the Intel TSX prefixes, specifically XACQUIRE and XRELEASE. If I modify my code correctly for Intel, what will happen when I attempt to run it on AMD machines? Intel says that these were designed to be backwards compatible, presumably meaning they do nothing on Intel CPUs without TSX. I know that AMD has not implemented TSX. But are these prefixes safe to run on AMD

问题 I'm a newbie to Android Development. Even though I referred the android developer website, I didn't figure out. On the customize Activity dialog box, when I unchecked the Backwards Compatiblity(Appcompat) in Android Studio 2.3.1 It gave me a hint as: If false, this activity base class will be Activity instead of AppCompatActivity Generally, what do android developers prefer? enabling backwards compatibility or without it? Can anyone explain me which one is better. 回答1: Android apps can be

问题 I often need to target Mac OS X versions that are older than the one I'm currently running. As I prefer to work with a bash shell and Makefiles, I do not use Xcode. Apple explicitly supports targeting older OS X versions, but I've always been confused by the redundancy of the two configuration steps that are usually taken to target older platforms: gcc is started using --macosx-version-min : gcc --mmacosx-version-min=10.6 .... The MACOSX_DEPLOYMENT_TARGET environment variable is set to the

问题 Is adding a variadic parameter to an existing Go function a breaking change? For example: // Old function func Foo(a int) // Updated to: func Foo(a int, params ...string) Callers of the API can omit the new parameter, so I would think the API is backwards-compatible. Can anyone provide an example where a user of the old API could not use the new API without changing their code? 回答1: I. Changing functions Calling them will continue to work without modification, but since the function
