With Clipping and Masking you can make some specified parts of elements transparent or opaque. Both can be applied to any HTML element.
Clipping
Clips are vector paths. Outside of this path the element will be transparent, inside it's opaque. Therefore you can define a clip-path property on elemen...
+ dictionaryWithCapacity:
Creates and returns a mutable dictionary, initially giving it enough allocated memory to hold a given number of entries.
NSMutableDictionary *dict = [NSMutableDictionary dictionaryWithCapacity:1];
NSLog(@"%@",dict);
- init
Initializes a newly allocated mut...
- removeObjectForKey:
Removes a given key and its associated value from the dictionary.
NSMutableDictionary *dict = [NSMutableDictionary dictionaryWithDictionary:@{@"key1":@"Easy",@"key2": @"Tutorials"}];
[dict removeObjectForKey:@"key1"];

A declaration introduces an identifier and describes its type, be it a type, object, or function. A declaration is what the compiler needs to accept references to that identifier. These are declarations:
extern int bar;
extern int g(int, int);
double f(int, double); /* extern can be omitted for f...
When writing a copy assignment operator, it is very important that it be able to work in the event of self-assignment. That is, it has to allow this:
SomeType t = ...;
t = t;
Self-assignment usually doesn't happen in such an obvious way. It typically happens via a circuitous route through vario...
The InputRange concept has three functions, example:
struct InputRange(T) {
@property bool empty();
@property T front();
void popFront();
}
In short, a way to
check if the range is empty
get the current element
move to the next element
To make our own type a InputRange, w...
A data race or race condition is a problem that can occur when a multithreaded program is not properly synchronized. If two or more threads access the same memory without synchronization, and at least one of the accesses is a 'write' operation, a data race occurs. This leads to platform dependent, p...
To create an build target that creates an library, use the add_library command:
add_library(my_lib lib.cpp)
The CMake variable BUILD_SHARED_LIBS controls whenever to build an static (OFF) or an shared (ON) library, using for example cmake .. -DBUILD_SHARED_LIBS=ON. However, you can explicitly se...
In this example will render five <li> tags
<ul id="render-sample">
<li v-for="n in 5">

</ul>
The =~ operator attempts to match a regular expression (set apart by /) to a string:
my $str = "hello world";
print "Hi, yourself!\n" if $str =~ /^hello/;
/^hello/ is the actual regular expression. The ^ is a special character that tells the regular expression to start with ...
(Copy an item and send the copies to every block that it’s linked to)
Unlike BufferBlock, BroadcastBlock’s mission in life is to enable all targets linked from the block to get a copy of every element published, continually overwriting the “current” value with those propagated to it.
Additionally,...
(Readonly variable: Memorizes its first data item and passes out copies of it as its output. Ignores all other data items)
If BufferBlock is the most fundamental block in TPL Dataflow, WriteOnceBlock is the simplest.
It stores at most one value, and once that value has been set, it will never be r...
(Select, one-to-one)
As with ActionBlock, TransformBlock<TInput, TOutput> enables the execution of a delegate to perform some action for each input datum; unlike with ActionBlock, this processing has an output. This delegate can be a Func<TInput, TOutput>, in which case processing of t...
(SelectMany, 1-m: The results of this mapping are “flattened”, just like LINQ’s SelectMany)
TransformManyBlock<TInput, TOutput> is very similar to TransformBlock<TInput, TOutput>.
The key difference is that whereas a TransformBlock<TInput, TOutput> produces one and only one outpu...
(FIFO Queue: The data that comes in is the data that goes out)
In short, BufferBlock provides an unbounded or bounded buffer for storing instances of T.
You can “post” instances of T to the block, which cause the data being posted to be stored in a first-in-first-out (FIFO) order by the block.

Primary Constructor
In Scala the primary constructor is the body of the class. The class name is followed by a parameter list, which are the constructor arguments. (As with any function, an empty parameter list may be omitted.)
class Foo(x: Int, y: String) {
val xy: String = y * x
/* now...
