The PreProcessPluginContext
is constructed each time rule execution is requested. The following data components are contained within the context:
evalTime
clientLanguage
clientTimeZoneOffset
focalPersonId
assertions
- This object is a set of strings, or more specifically,
Set<String>
, and is a placeholder for assertions and is instantiated and given to Drools as a global variable. Drools may write to this set to provide the calling code with the information about the inferencing performed on the input data. (As of today--2014-09-20) the assertions object is not being used external to Drools, as there is a rule that is commonly being used which assembles the assertions into a comma-delimited list, as part of the vMR output.)
- This object is a set of strings, or more specifically,
globals
- This (new) object is a Map of String to Object, or more specifically,
Map<String, Object>
. The key of each map entry may be any given String, which is typically used as a Global within the Drools context. Names are restricted to any value other than the following:- read-only:
evalTime
,clientLanguage
,clientTimeZoneOffset
,focalPersonId
- read-write:
assertions
, andnamedObjects
- read-only:
- This (new) object is a Map of String to Object, or more specifically,
allFactLists
- This object is a Map of Class to List, or more specifically,
Map<Class<?>, List<?>>
. The key of each map entry may be aClass
of any given type, though Plugins should restrict the types to OpenCDS-internal components of the vMR. - Fact Lists are the facts that Drools uses for inferencing–these contain data from the vMR.
- All facts that are submitted are returned unless they are retracted by the rules. They are returned to OpenCDS, but OpenCDS only puts them into the output XML if they are flagged to be returned (using
ClinicalStatement
fields:clinicalStatementToBeRoot
and/ortoBeReturned
; aClinicalStatement
marked asclinicalStatementToBeRoot
andtoBeReturned
will return all child elements).
- This object is a Map of Class to List, or more specifically,
- namedObjects
- This object is a Map of String to Object, or more specifically,
Map<String, Object>
. The key of each map entry may be any given String, which is typically used within Drools. - Named objects are currently (at the University of Utah) used by Drools rules for obtaining result fact lists.
globals
- This object is a Map of String to Object, or more specifically,

,clientLanguage

,focalPersonId

as follows:- adds named objects to what is found to be returned in submitted
allFactLists
.
- adds named objects to what is found to be returned in submitted
- This object is a Map of String to Object, or more specifically,
- cache
- Cache is a cache of data within an OpencdsCache cache region, where plugins may store the data they support for future processing, as in the case of, e.g., SupportingData.

The PostProcessPluginContext
is constructed each time rule execution has completed. The following data components are contained within the context:
evalTime
clientLanguage
clientTimeZoneOffset
focalPersonId
assertions
- This object is a set of strings, or more specifically,
Set<String>
, and is a placeholder for assertions and is instantiated and given to Drools as a global variable.

- This object is a set of strings, or more specifically,

- This object (created and added to the
PreProcessPluginContext
) is a Map of String to Object, or more specifically,Map<String, Object>
. The key of each map entry may be any given String, which is typically used as a Global within the Drools context. Names are restricted to any value other than the following:- read-only:
evalTime

- read-write:
assertions
, andnamedObjects
- read-only:
- This object (created and added to the
resultFactLists
- This object is a Map of String to List, or more specifically,
Map<String, List<?>>
. Data contained by this map are the result fact lists, which are the final return value of the DroolsAdapter.getOneResponse method and OpenCDS post processing. - Effectively this is a copy of
allFactLists
(above) with any changes made by Drools, and the contents ofnamedObjects
(added by OpenCDS after Drools processing).namedObjects
informs the output XML generator to determine which elements should be included in the output XML.- Note: elements of namedObjects will not cause rules to fire, and hence must also be added to the fact lists.
