any file to Mac OS X Lion 64-bit
May a copy of the same program's executable code be copied to Lion 64 bit Lion OS X? Will the modifications on the file(s) copied to Lion OS X affect Lion 64-bit?
A:
No. Your Mac software is read-only. You can't write any data to a Mac software without modifying it. You can however write data to a file with that software, so if you want to share a modified file you'll need to use another format than a file.
The executable code for the Mac software is also read-only. It's copied to a temporary directory on your disk, just like any other data that you copy to it. The code is not copied to the disk at all.
The article you cite, is a bit out of date. Lion 64-bit runs on 10.6.8 and earlier and is completely different.
Q:
What is the advantage of Angular Custom Pipe?
Angular 2 provides some built in Pipe which you can use. But we can implement a custom Pipe also. I am not able to understand what is the difference between a custom Pipe and a built in Pipe.
A built-in Pipe is one of the two basic building blocks of the Angular Framework:
[the] change detection mechanism
A built-in Pipe is a simple mechanism that triggers the change detection for each of its subscribers, all in a single pass.
[the] selector mechanism
A built-in Pipe is a component that selects a given property of a given class from an array of objects.
One of the main reasons to use a built-in Pipe is when you want to change the data flow. For example:
Your pipe supports searching for a username from your database (or any other source) and return the user.
return [searchUser];
return "user";
return "no user found";
Using the "User" Pipe in the first example doesn't have any effect on the change detection since the data will remain unchanged.
The second example will affect the change detection since you are passing a new value.
It's also possible to implement a custom Pipe that triggers a change detection when
