NSURL *url = [NSURL URLWithString:@"http://www.example.com/images/apple-tree.jpg"]; NSString *fileName = [url lastPathComponent]; // fileName = "apple-tree.jpg"

In this case, you want to have the expression compiled before the evaluations, so that each call to evaluate does not compile the same expression. The simple syntax would be: XPath xPath = XPathFactory.newInstance().newXPath(); //Make new XPath XPathExpression exp = xPath.compile("/documentat...

Prior to C++17, when writing a template non-type parameter, you had to specify its type first. So a common pattern became writing something like: template <class T, T N> struct integral_constant { using type = T; static constexpr T value = N; }; using five = integral_constant&l...

Prior to C++17, template deduction cannot deduce the class type for you in a constructor. It must be explicitly specified. Sometimes, however, these types can be very cumbersome or (in the case of lambdas) impossible to name, so we got a proliferation of type factories (like make_pair(), make_tuple(...

Suppose you have a collection elements, and you want to create another collection containing the same elements but with all duplicates eliminated: Collection<Type> noDuplicates = new HashSet<Type>(elements); Example: List<String> names = new ArrayList<>( Arrays....

// First load a product object $product->getSku(); $product->getName(); // Alternative method $product->getData('sku'); $product->getData('name');

// First load a collection object foreach($collection as $product) { $product->getSku(); $product->getName(); // Alternative method $product->getData('sku'); $product->getData('name'); }

Given below is a simple example to train a Caffe model on the Iris data set in Python, using PyCaffe. It also gives the predicted outputs given some user-defined inputs. iris_tuto.py import subprocess import platform import copy from sklearn.datasets import load_iris import sklearn.metrics ...

In many cases, we can avoid problems when an Activity is re-created by simply using fragments. If your views and state are within a fragment, we can easily have the fragment be retained when the activity is re-created: public class RetainedFragment extends Fragment { // data object we want to ...

Demonstrate how to embed a lua interpreter in C code, expose a C-defined function to Lua script, evaluate a Lua script, call a C-defined function from Lua, and call a Lua-defined function from C (the host). In this example, we want the mood to be set by a Lua script. Here is mood.lua: -- Get versi...

To setup a WebRTC-based communication system, you need three main components: A WebRTC signaling server To establish a WebRTC connections, peers need to contact a signaling server, which then provides the address information the peers require to set up a peer-to-peer connection. Signaling serv...

You can add an image to a view's layer simply by using its contents property: myView.layer.contents = UIImage(named: "star")?.CGImage Note that the UIImage needs to be converted to a CGImage. If you wish to add the image in its own layer, you can do it like this: let myLayer = CA...

Create a new class implementing IXposedHookLoadPackage and implement the handleLoadPackage method: public class MultiPatcher implements IXposedHookLoadPackage { @Override public void handleLoadPackage(XC_LoadPackage.LoadPackageParam loadPackageParam) throws Throwable { ...

When executing a Bash script, parameters passed into the script are named in accordance to their position: $1 is the name of the first parameter, $2 is the name of the second parameter, and so on. A missing parameter simply evaluates to an empty string. Checking for the existence of a parameter can...
