Generic method usage in Spaces API
----------------------------------
Key: RIVER-384
URL: https://issues.apache.org/jira/browse/RIVER-384
Project: River
Issue Type: Improvement
Components: com_sun_jini_outrigger, net_jini_space
Reporter: James Grahn
Priority: Minor
Use generics in the method signatures to minimize casting, in this manner:
public <T extends Entry> T read(T template, Transaction txn, long timeout)
(Similar transforms could be made to the majority of the methods within
Javaspace.)
The generic is defined at the method-level, enforcing that the type returned is
the type of the template (and that template extends Entry).
This is precisely the current contractual obligation of the method.
This would have the following benefits:
1) Users no longer have to cast everything they receive from a read or take
method.
2) The compiler can enforce part of the contract that was previously only
covered by documentation.
