---------------------------------------
Summary: Ability to set NilReason on Boolean, Integer, Double and
String objects
Key: SIS-115
URL: https://issues.apache.org/jira/browse/SIS-115
Project: Spatial Information Systems
Issue Type: Improvement
Components: Utilities
Affects Versions: 0.3
Reporter: Martin Desruisseaux
Assignee: Martin Desruisseaux
Fix For: 0.4
In SIS 0.3, {{NilReason}} are stored by implementations of the
{{org.apache.sis.xml.NilObject}} interface. However we can not implement this
interface for {{Boolean}}, {{Integer}}, {{Double}}, {{String}} and other JDK
classes that are {{final}}.
The proposed workaround is to provide an internal {{PrimitiveTypeProperties}}
class which will assign {{NilReason}} to a specific instance of {{Boolean}} or
other JDK classes, using an {{IdentityHashMap}}. Inconvenient is that testing
{{if (object instanceof NilObject)}} is no longer sufficient - we now need to
use the {{NilReason.forObject(Object)}} method.
