Method Details

checkNonNull

static void checkNonNull(Object obj,
 String name)

This method is similar to Objects.requireNonNull(). But this one is available for JDK 1.6 which is the current target of args4j. I didn't want to break compatibility with JDK 1.6.

Parameters:

obj - the object to check for null value.

name - the object name. If obj is null, then an exception is constructed from this name.
