Annotation Type SemiStrict

@Target(value={METHOD,TYPE})
 @Retention(value=RUNTIME)
public @interface SemiStrict

Annotation applied to a user-defined function that indicates that the function always returns null if one or more of its arguments are null but also may return null at other times.

Compare with Strict:

• A strict function returns null if and only if it has a null argument
• A semi-strict function returns null if it has a null argument
