Ate Douma created SCXML-259:
-------------------------------
Summary: Complete implementation and handling of system variables
_event and _ioprocessors
Key: SCXML-259
URL: https://issues.apache.org/jira/browse/SCXML-259
Project: Commons SCXML
Issue Type: New Feature
Reporter: Ate Douma
Assignee: Ate Douma
Fix For: 2.0
The SCXML [System
Variables|https://www.w3.org/TR/2015/REC-scxml-20150901/#SystemVariables]
_event was only minimally implemented so far.
The _event.sendid, _event.origin, _event.origintype, _event.invokeid all need
to be set and handled accordingly to the external communication requirements,
including their proper error handling and feedback/return values from an
invoked process.
The SCXML [Event I/O
Processors|https://www.w3.org/TR/2015/REC-scxml-20150901/#eventioprocessors]
implementation and handling was also not complete yet.
Besides completing the handling of the #_internal, #_parent and #_invokeid
processors, also
the 'location' field for the standard CXMLEventProcessor needs to be made
available.
To support the extended _event variable handling a new EventBuilder class will
be introduced, which can/should be used to build a TriggerEvent instead of
instantiating these directly.
Furthermore to align with the specification naming, the TriggerEvent#payload
field and getter method will be renamed to #data (getData()).
Finally, this also requires better, and fixed, handling of the management and
communication (bi-directionally) with the Invoker and the statemachine invoked.
As result the AsyncTrigger class no longer is (nor can be) used and will be
dropped.
Alltogether this will fix another 12+ W3C SCXML IRP tests!
