Samuel,
thanks for the advices!

As for this, well, I must be missing something fairly obvious, but... how on
earth could be just anything (globalID-based or not) faster than my cache-in-EO
code, which (somewhat simplified for better readability) looks essentially like
this:
class OCSEnterpriseObject extends ERXGenericRecord {
private NSMutableDictionary archivedObjectsCache=nil
def unarchivedObjectForKey(String archivedkey) {
def obj=this.@archivedObjectsCache[archivedkey]
if (obj==NSKeyValueCoding.Null) return nil
if (obj==nil) {
NSData d=storedValueForKey(archivedkey)
if (d!=nil) obj=Archivation.objectFromArchivedData(d)
if (this.@archivedObjectsCache==nil)
this.@archivedObjectsCache=NSMutableDictionary.dictionary
this.@archivedObjectsCache[archivedkey]=obj!=nil?obj:NSKeyValueCoding.Null
}
obj
}
void setUnarchivedObjectForKey(obj,String archivedkey) {
if (this.@archivedObjectsCache==nil)
this.@archivedObjectsCache=NSMutableDictionary.dictionary
this.@archivedObjectsCache[archivedkey]=obj!=nil?obj:NSKeyValueCoding.Null
if (obj!=nil) obj=Archivation.archivedDataFromObject(obj)
takeStoredValueForKey(obj,archivedkey)
}
}
? I can see memory possibly saved with some sharing if more different EOs
happen to have same attributes (but it would complicate the code by forcing
some kind of copy-on-write-if-differs behaviour, and I rather suspect it would
not be worth the effort), but I simply can't see any possible speedup.
What am I overlooking?
Thanks and all the best,
OC
