Ampersand | Dynamic Type Support for Custom Fonts | iOS library

You can use a relatively simple pattern match to do this.

The interesting bit here is the \p{Hebrew}, which allows you to match every character with a specific Unicode property. The rest is just beginning ^ and end $ of string, and a quantifier + to say one or more.

this is a pointer that keeps the address of the current object. So dereferencing the pointer like *this you will get the lvalue of the current object itself. And the return type of the copy assignment operator of the presented class is A&. So returning the expression *this you are returning a reference to the current object.

According to the C++ 17 Standard (8.1.2 This)

1 The keyword this names a pointer to the object for which a non-static member function (12.2.2.1) is invoked or a non-static data member’s initializer (12.2) is evaluated.

Consider the following code snippet as an simplified example.

You have options.

You can change your form to something like this:

If you really want to replace the existing files but also know which ones where replaced, an alternative would be to redirect the verbose stream to the success stream and filter by those lines containing "Remove File". Expand-Archive when using -Verbose, will output the following when replacing (removing first and then creating) a file:

Performing the operation "Remove File" on target .....

In that sense, you can do the following:

I don't have access to an Azure tennant right now to test and I actually don't have experiences with the Azure CLI in general but I'd expect this to work:

Why do I have two methods, one with the const keyword, and one without it?

The const keyword sets a constraint that prevents the function from modifying the object. For example, if you use the const keyword in a setter, you'll get a compiler error.

So the first function won't allow any modification on the object and in this case it will return a copy of the accessed element. The first function is a getter in disguise, it is a read only access, so to speak.

What does the ampersand (&) in my second method do?

The second function, instead, has the ampersand after the type, which means that it will return a reference of the returned value and not a copy of it. The returned value is part of the object, so returning a reference to it implies a potential modification and the const keyword wouldn't allow it.

So this second function is a setter in disguise, it is a write access.

Why can I set a value at a given index using square brackets, when none of my methods are setters, and which of these two methods is invoked when I set a value?

As we've seen, the second function acts like a setter. When you use it, the returned value is a reference to the real element inside your object, and is valid for assignation (we call it a lvalue, more about them here).

The point of this overload is: whenever you use the operators for a read operation (right side of the assignation or as a parameter) the first function will be called. If you use it for a write operation, it will be the second. In fact, this is how the same operator works for the STL containers you are probably using in your code.

You are using the xsl:call-template inside of xsl:for-each select="tokenize($LOB_Hier, '\|')", that is, inside of a for-each over a sequence of strings (strings are atomic values) so in your called template the context item is a simple string. Yet you pretend you want to process child elements named Group with e.g. xsl:for-each select="Group" inside of the called template, presumably child elements of some input node.

So before the xsl:for-each select="tokenize($LOB_Hier, '\|')", you need to store a node, e.g. the context node with and pass that on also as a parameter to the template you call to then use $root-node/Group where you want to process the Group children or probably rather $root-node/RegionLOBs/Group if I read your document structure correctly.

In manpage of bash, it says:

When bash starts a job asynchronously (in the background), it prints a line that looks like:

The whole problem stems from the forwarding references using same symbols as rvalue ones, but not being the same.

Take the following code:
