Sandro Martini commented on PIVOT-82:
-------------------------------------
Hi,
in some cases could be useful to have definitions like these:
// generic data structures, to use as placeholder instead of null
public static final Object[] EMPTY_ARRAY = new Object[0];
public static final List EMPTY_LIST = Collections.EMPTY_LIST;
public static final Map EMPTY_MAP = Collections.EMPTY_MAP;
public static final Set EMPTY_SET = Collections.EMPTY_SET;
These are taken for my code, and are related to standard Java Collections,
maybe a similar thing could be done inside Pivot Collection classes, and use
them as placeholders, when/if required ... or could be moved in some Utility
class, but I'd prefer the first approach.
