The Java Native Interface (JNI) allows you to call Java functions from native code. Here is a simple example of how to do it: Java code: package com.example.jniexample; public class JNITest { public static int getAnswer(bool) { return 42; } } Native code: int getTheAnswer(...

private static void saveItem(List<EventTracker> items) { List<WriteRequest> wrList = new ArrayList<>(); try { for (EventTracker item : items) { WriteRequest wreqItem; wreqItem = getWriteRequest(item); wrList.add(wreqItem);...

private static WriteRequest getWriteRequest(EventTracker event) { WriteRequest wreq = null;// = new WriteRequest(); if (event != null) { Map<String, AttributeValue> attributeMap = new HashMap<String, AttributeValue>(); addAttribute(attributeMap, "ev...

This example shows multiple producers and consumers sharing the same buffer. Protected entries in Ada implement a queue to handle waiting tasks. The default queuing policy is First In First Out. ------------------------------------------------------------------ -- Multiple producers and consumers ...

To simply open a URL, use the webbrowser.open() method: import webbrowser webbrowser.open("http://stackoverflow.com") If a browser window is currently open, the method will open a new tab at the specified URL. If no window is open, the method will open the operating system's default b...

The webbrowser module also supports different browsers using the register() and get() methods. The get method is used to create a browser controller using a specific executable's path and the register method is used to attach these executables to preset browser types for future use, commonly when mu...

Detailed instructions on getting activemq set up or installed.

Currently (as of version 2.11.0) there is no built-in functionality to move an already existing worktree. This is listed as an official bug (see https://git-scm.com/docs/git-worktree#_bugs). To get around this limitation it is possible to perform manual operations directly in the .git reference fil...

To include the base64 module in your script, you must import it first: import base64 The base64 encode and decode functions both require a bytes-like object. To get our string into bytes, we must encode it using Python's built in encode function. Most commonly, the UTF-8 encoding is used, howeve...

The base64 module also includes encoding and decoding functions for Base32. These functions are very similar to the Base64 functions: import base64 # Creating a string s = "Hello World!" # Encoding the string into bytes b = s.encode("UTF-8") # Base32 Encode the bytes e = b...

The base64 module also includes encoding and decoding functions for Base16. Base 16 is most commonly referred to as hexadecimal. These functions are very similar to the both the Base64 and Base32 functions: import base64 # Creating a string s = "Hello World!" # Encoding the string into...

Adobe created it's own encoding called ASCII85 which is similar to Base85, but has its differences. This encoding is used frequently in Adobe PDF files. These functions were released in Python version 3.4. Otherwise, the functions base64.a85encode() and base64.a85encode() are similar to the previous...

Just like the Base64, Base32, and Base16 functions, the Base85 encoding and decoding functions are base64.b85encode() and base64.b85decode(): import base64 # Creating a string s = "Hello World!" # Encoding the string into bytes b = s.encode("UTF-8") # Base85 Encode the byte...

Understanding the concept To understand content negotiation in Web API, it is important to understand the term Resource. On the web, any information that we can access can be referred as HTTP resource. There is a tremendous amount of material to view on the web which has different content type suc...

The following example is an example of a basic server: # Imports the Flask class from flask import Flask # Creates an app and checks if its the main or imported app = Flask(__name__) # Specifies what URL triggers hello_world() @app.route('/') # The function run on the index route def hello...

The two most common HTTP methods are GET and POST. Flask can run different code from the same URL dependent on the HTTP method used. For example, in a web service with accounts, it is most convenient to route the sign in page and the sign in process through the same URL. A GET request, the same that...
