This is not too hard to do by hand, but will depend on the size of your interface. The cases where I’ve done it were to enable use of our C++ library from within pure C code, and thus SWIG was not much help. (Well maybe SWIG can be used to do this, but I’m … Read more
Decorate the class with a function that walks through the class’s attributes and decorates callables. This may be the wrong thing to do if you have class variables that may happen to be callable, and will also decorate nested classes (credits to Sven Marnach for pointing this out) but generally it’s a rather clean and … Read more
Others have mentioned that certain constructs such as Collections require objects and that objects have more overhead than their primitive counterparts (memory & boxing). Another consideration is: It can be handy to initialize Objects to null or send null parameters into a method/constructor to indicate state or function. This can’t be done with primitives. Many … Read more
You can also update task wrapper(type: Wrapper) { gradleVersion = ‘4.4’ distributionUrl = distributionUrl.replace(“bin”, “all”) } to wrapper { gradleVersion = ‘4.4’ distributionUrl = distributionUrl.replace(“bin”, “all”) } As Overriding built-in tasks deprecated in 4.8 now produces an error. Attempting to replace a built-in task will produce an error similar to the following: Cannot add task … Read more
The JVM is caching Integer values. Hence the comparison with == only works for numbers between -128 and 127. Refer: #Immutable_Objects_.2F_Wrapper_Class_Caching
Update: I’ve succeeded in linking a small test C++ class with Go If you wrap you C++ code with a C interface you should be able to call your library with cgo (see the example of gmp in $GOROOT/misc/cgo/gmp). I’m not sure if the idea of a class in C++ is really expressible in Go, … Read more
In general, a wrapper class is any class which “wraps” or “encapsulates” the functionality of another class or component. These are useful by providing a level of abstraction from the implementation of the underlying class or component; for example, wrapper classes that wrap COM components can manage the process of invoking the COM component without … Read more
