See [1] for description and protocol documentation. The material should be moved here and rewritten into a specification.
Links to specification details should go right here.
Specification exits
The CapTP specification, per se, does not specify these choices:
- The Miranda protocol all objects exposed over CapTP are expected to respond to. CapTP requires at least __whenMoreResolved.
- The format in which CapTP messages are serialized for transmission over a byte stream.
- The format in which objects embedded in CapTP messages are serialized in that stream.
- The set of graph exits; that is, those objects/makers which both ends know about and can refer to in their serialized objects. The ad-hoc serialization comity proposal would mitigate this.
- The format in which objects embedded in CapTP messages are serialized in that stream.
In an E system, these holes are specified to be filled with, respectively:
- Miranda protocol
- XXX Write this specification. See CapTP impl in E-on-CL
- Data-E, with CapTP-specific details as below.
Data-E configuration
CapTP as fully implemented in E-on-Java uses Java serialization. The work-in-progress implementation of CapTP in E uses Data-E to serialize CapTP message arguments:
(This has all been made up by User:Kevin Reid; please critique.)
The graph exits which are CapTP-specific are:
-
"CapTP_1_descs"
- The uncall recipient for all descriptors. For example, an ImportDesc is represented in Data-E as
CapTP_1_descs.import(importPos)
. -
"CapTP_1_locatorUnum"
- The local presence of the LocatorUnum.
XXX Specify exactly what other graph exits should be available. for now it's the subgraph kit's default scope plus Ref and import__uriGetter.
