[jboss-jira] [JBoss JIRA] Commented: (JBRULES-2455) Process variable length comma separated lists within cells

Graham Gear commented on JBRULES-2455:
--------------------------------------
Discussed with Mark Proctor and decided to implement in a generic manner to support
pluggable logical operations via a paramaterised forall reserved word:
property = $forall(,)
property = $forall(&&)
property = $forall(||)
etc
I have developed a patch against trunk (33335) localised to:
M
drools-decisiontables/src/test/java/org/drools/decisiontable/parser/LhsBuilderTest.java

drools-decisiontables/src/main/java/org/drools/decisiontable/parser/LhsBuilder.java

Process variable length comma separated lists within cells
----------------------------------------------------------
Key: JBRULES-2455
URL: https://jira.jboss.org/browse/JBRULES-2455
Project: Drools
Issue Type: Feature Request
Security Level: Public(Everyone can see)
Components: drools-decisiontables
Affects Versions: 5.1.0.M1
Reporter: Graham Gear
Assignee: Mark Proctor
Attachments: VariableLengthListDecisionTablePatch.diff
Given a decision table column:
VALUE1, VALUE2, VALUE3
VALUE4, VALUE5
It is required that a DRL snippet could be constructed to utilise all available comma
separated tokens and not have to hard code $1, $2 etc references.
Eg a snippet could be:
property == $forall_param_and
resulting in the compiled snippet:
property == "VALUE1" && property == "VALUE2" &&
property == "VALUE3"
property == "VALUE4" && property == "VALUE5"
