When you reference a class that has not been imported, IntelliJ IDEA helps you locate this file and add it to the list of imports. You can import a single class or an entire package, depending on your settings. The import statement adds to the imports section, but the cursor does not move from the current position, and your current editing session does not interrupt. This feature is known as the Import Assistant.
The same possibility applies to the XML, JSP, and JSPX files. When you type a tag with an unbound namespace, import assistant suggests to create a namespace and offers a list of appropriate choices.
When you reference a PHP class that is defined outside the current file, IntelliJ IDEA locates the class definition, whereupon you can do one of the following:
- Have IntelliJ IDEA automatically complete the fully qualified class name, including the namespace the class is defined in. This will result in littering your code.
- Have IntelliJ IDEA automatically complete the short class name and import the namespace the class is defined in.
- Import the namespace manually using a quick fix.
