firstNonNull

@SafeVarargs

public static <T> T firstNonNull(@Nullable @NullableElements
 T... objects)

Return the first from a list of arguments that is non-null, or null if all arguments are null.

This is similar to Guava's MoreObjects.firstNonNull(Object, Object), except it takes more than 2 arguments, and also doesn't throw a null pointer exception if all arguments are null.

Type Parameters:

T - the type of arguments being evaluated

Parameters:

objects - the list of object references to evaluate

Returns:

the first non-null argument, or null if all arguments are null
