| Pointcut Detail |
Specify what the application code is that should be subject to the pattern test.
Ex: pointcut applicationCode(): within(patterntesting.sample.*)
Specify which code is allowed to have null parameters.
Ex: execution(@NullArgsAllowed * *..*(*, ..)) || execution(@NullArgsAllowed *..new(*, ..))
Specify which methods may return null. Some methods (like find methods or getters) may return a null value.
Ex: execution(@MayReturnNull Object+ *..*(..))
Addresses all methods (or constructors) with at least one argument which should not be given as null parameter. For performance reason this is limited only to public methods (or constructors)
| Advice Detail |
before(): invalidNullParameter..
If a (null) parameter is detected something is wrong with the application code. Inner classes will be skipped because they are handled different by the compiler (for private static inner classes it adds an additional argument for the default constructor. But this additional argument is always null).
