Create @NotNull or @RequiresNonNull annotation to allow null checks with custom exception ----------------------------------------------------------------------------------------- Key: LOGTOOL-109 URL: https://issues.jboss.org/browse/LOGTOOL-109 Project: Log Tool Issue Type: Feature Request Reporter: James Perkins Use an {{@NotNull}} or {{@RequiresNonNull}} annotation on a method to generate a {{null}} check and throw, by default, an {{IllegalArgumentException}} if null. Also clean the stack trace. {code:java|title=Example Interface} @Message(id = 123, value = "Name cannot be null") @NotNull(IllegalArgumentException.class) void requireNotNull(String name); {code} {code:java|title=Example Generated Code} @Override public void requireNotNull(final String name) { if (name == null) { final IllegalArgumentException result = new IllegalArgumentException(String.format(invalidUser$str(), name)); final StackTraceElement[] st = result.getStackTrace(); result.setStackTrace(Arrays.copyOfRange(st, 1, st.length)); } } {code} The {{@Param}} annotation could be used along with {{@Pos}} for formatting possibly.
