java.lang.Object
de.japkit.test.members.constructor.ConstructorTemplate.nullCheck
Enclosing class:
ConstructorTemplate
@CodeFragment(condFun=hasNotNull.class,
              imports=java.util.Objects.class,
              code="Objects.requireNonNull(#{surrounded}, \"#{name} must not be null.\")")
class ConstructorTemplate.nullCheck
extends java.lang.Object
A code fragment that adds a null check to the field assignment if the field has a NotNull annotation. It expects the field (from the annotated class) as current src.

Since nullCheck is used as a fragment that surrounds other code, there is some special EL variable "surrounded" available here that contains the code to be surrounded.

If the field has no NotNull annotation, the fragments does nothing. For a surrounding fragment this means, the code to be surrounded is left as it is.
