buildCheckerIfNeeded

public static IgnorePropertiesUtil.Checker buildCheckerIfNeeded(Set<String> toIgnore,
 Set<String> toInclude)

Factory method for creating and return a IgnorePropertiesUtil.Checker instance if (and only if) one needed.

Parameters:

toIgnore - Set of property names to ignore (may be null)

toInclude - Set of only property names to include (if null, undefined)

Returns:

Checker, if validity checks are needed; null otherwise

combineNamesToInclude

public static Set<String> combineNamesToInclude(Set<String> prevToInclude,
 Set<String> newToInclude)

Helper that encapsulates logic for combining two sets of "included names": default logic is to do intersection (name must be in both to be included in result)

Parameters:

prevToInclude - Existing set of names to include, if defined; null means "not defined"

newToInclude - New set of names to included, if defined; null means "not defined"

Returns:

Resulting set of names, using intersection if neither null; or the non-null one (if only one is null); or null if both arguments null.
