Annotation Type NotNull


  • @Documented
    @Retention(RUNTIME)
    @Target({FIELD,LOCAL_VARIABLE,PARAMETER,METHOD})
    public @interface NotNull
    This annotation type is used to indicate that the associated field, local variable, method or constructor parameter, or method return value is not allowed to be null. This annotation type is not strictly enforced by the compiler, but development environments may be configured to warn or reject attempts to use null values where non-null values are expected.

    This annotation type will appear in the generated Javadoc documentation for classes and interfaces that include it.
