[Phptmapi-discuss] Construct::equals() and Construct::hashCode()

[Johannes S. <top...@fr...>]

Hi all,
as PHPTMAPI is aligned to TMAPI I now wanted to update 
Construct::equals() and Construct::hashCode() according to updated 
semantics of equals() and hashCode() in final RC of TMAPI 2.0 [1]. Well, 
I am not really satisfied with this changing but missed the discussion 
on TMAPI mailing list. In final RC the semantics of equals() has changed 
from comparing the identity of TM CONSTRUCTS towards comparing the 
identity of (Java) OBJECTS. This is significantly different. Identity of 
TM constructs is "materialized" by TM system specific arbitrary 
identifiers [2]. IMO in federation of different topic maps from 
different TM systems processing of such construct identifiers must be 
omitted; focus is on processing the identity of subjects.
To be honest: I'd like to preserve current semantics of PHPTMAPI 
equals(). Implementors will know how to identify PHP objects [3]. Thoughts?

Best regards,
Johannes
