To create a Behavior just extend the CoordinatorLayout.Behavior class. Extend the CoordinatorLayout.Behavior Example: public class MyBehavior<V extends View> extends CoordinatorLayout.Behavior<V> { /** * Default constructor. */ public MyBehavior() { ...

You can use the CoordinatorLayout.Behavior to create dependencies between views. You can anchor a View to another View by: using the layout_anchor attribute. creating a custom Behavior and implementing the layoutDependsOn method returning true. For example, in order to create a Behavior for m...

Using a list object you can create a fully functional generic Stack with helper methods such as peeking and checking if the stack is Empty. Check out the official python docs for using list as Stack here. #define a stack class class Stack: def __init__(self): self.items = [] ...

Smack (Java) Using Smack 4.1 It is recommended to include Smack as Maven dependency in your project (e.g. by using gradle or Maven). Otherwhise the following Smack artifacts/jars have to be added manually to the classpath: smack-core, smack-extensions, smack-experimental, smack-im, smnack-tcp,...

When you really need to script ssh connection, piping the password into the ssh command does not work (echo passw0rd | ssh host). It is because the password is not read from standard input, but directly from TTY (teleprinter, teletypewriter, Teletype for historical reasons). But there is sshpass to...

Generic arrays in Kotlin are represented by Array<T>. To create an empty array, use emptyArray<T>() factory function: val empty = emptyArray<String>() To create an array with given size and initial values, use the constructor: var strings = Array<String>(size = 5, init ...

# creates a function with no arguments, which returns 3 get_three = () -> return 3 # same as above get_three = -> 3 # creates a function with arguments add_three = (num) -> num + 3 # multiple arguments, etc. add = (a, b) -> a + b

We can define a function to perform function composition using anonymous function syntax: f ∘ g = x -> f(g(x)) Note that this definition is equivalent to each of the following definitions: ∘(f, g) = x -> f(g(x)) or function ∘(f, g) x -> f(g(x)) end recalling that in Julia,...

One application of closures is to partially apply a function; that is, provide some arguments now and create a function that takes the remaining arguments. Currying is a specific form of partial application. Let's start with the simple function curry(f, x) that will provide the first argument to a ...

This method works by incrementing an integer from 0 to the greatest index in the array. $colors = ['red', 'yellow', 'blue', 'green']; for ($i = 0; $i < count($colors); $i++) { echo 'I am the color ' . $colors[$i] . '<br>'; } This also allows iterating an array in reverse order wi...

Direct loop foreach ($colors as $color) { echo "I am the color $color<br>"; } Loop with keys $foods = ['healthy' => 'Apples', 'bad' => 'Ice Cream']; foreach ($foods as $key => $food) { echo "Eating $food is $key"; } Loop by reference In the fo...

Profiles permit the programmer to organize maps into classes, enhancing code readability and maintainability. Any number of profiles can be created, and added to one or more configurations as needed. Profiles can be used with both the static and instance-based APIs. public class User { public...

If there is no need for frontend in your next project, you can run sails new with additional flag --no-frontend. sails new NameOfProject --no-frontend This will generate everything needed for backend and will omit view, assets and grunt files. More about command line and sails-new: http://sails...

In the extension code you can use any chrome.* API if you decalared the required permissions. In addition, some API's works only from background pages, and some API's works only from content scripts. You can use most of chrome.tabs methods declaring any permissions. Now we focus on chrome.tabs.crea...

Merge Sort is a divide-and-conquer algorithm. It divides the input list of length n in half successively until there are n lists of size 1. Then, pairs of lists are merged together with the smaller first element among the pair of lists being added in each step. Through successive merging and through...
