actual annotation

The actual annotation marks a member as refining an inherited member.

Usage 

class Example() {
    shared actual String string = "example";
}

Description

Methods, attributes, and member classes may be annotated actual, and only when the member that they are refining was annotated default for formal.

Because a member that is refinable must be visible outside the scope of the type it's defined in, an actual member is necessarily shared.

actual is the Ceylon equivalent of Java's @Override annotation, but unlike @Override it must be used when refining a member.
