intellij-idea Live Templates Insert the name of the current class
Example
Consider the utility class pattern:
a class with only static methods and no fields.
It's recommended to prevent instantiation of such classes by adding a private a constructor.
This live template example makes it easy to add a private constructor to an existing class, using the name of the enclosing class.
private $className$() {
throw new AssertionError("utility class, forbidden constructor");
}
Applicable in Java: declaration scope.
Click Edit variables to define the className variable as the built-in className() expression, and check the Skip if defined box to avoid prompting for a custom name, which is unnecessary in this example.
For example, inside a class like this:
class ListUtils {
// ...
}
When you type "utility_class" (the abbreviation), this will insert a constructor like this:
class ListUtils {
private ListUtils() {
throw new AssertionError("utility class, forbidden constructor");
}
// ...
}
