[node8-android] Instantiation of JavaObjects

Global resources:

• #ClassMap: Java class name -> s8 supporting class, mapping

Local resources:

• #cachedInstance: property of handle where supporting s8 class is cached
• delegationChain: a collection of all Java superclass names ordered from (handle #getClass #getName) to java.lang.Object), where aClassName is before than anotherClassName if aClassName is more concrete than anotherClassName

Algorithm

• if handle is nil then ^nil
• if (isObject: handle) then ^handle
• if (typeOf: handle#hashCode = 'undefined') then ^PoolDictionary @ handle
• if handle has a hashCode
  • then
    • if handle has #cachedInstance then ^aClass at handle#cachedInstance cache
  • else
    • choices := delegationChain removeLast ("exclude java.lang.Object")
    • foundClass := nil
    • for each javaClassName in choices do:
      • if ClassMap includesKey: javaClassName
        • then foundClass := ClassMap at: javaClassName
        • else
          • for each subclass of self do:
            • if (subclass javaFullName = javaClassName)
              • then
                • foundClass := subclass
                • break
          • end loop
      • foundClass notNil
        • then
          • ClassMap at: javaClassName put: foundClass. ("put found in ClassMap for next search")
          • wrapper := foundClass basicNew: handle.
          • put wrapper in handle#chachedInstance
          • ^wrapper
    • end loop
    • ^" Missing s8 support for handle "
