Hi all, I am looking at using the Matrix style decision tables. There is not a lot of documentation on these, but I have also found the spring config for them is lacking.
There is a test case here - https://github.com/droolsjbpm/drools/blob/master/drools-decisiontables/src/test/java/org/drools/decisiontable/SpreadsheetCompilerUnitTest.java that shows really that it complies to a DRL. The method call for building the compiler SpreadsheetCompiler.compile() takes an extra argument .. a spreadsheet listener. final SpreadsheetCompiler converter = new SpreadsheetCompiler(); final String drl = converter.compile( stream, InputType.XLS, new RuleMatrixSheetListener() ); But the Spring configuration doesn't seem to support that type.. (i.e. looking at the code in the UnitTest, a "RuleMatrixSheetListener" is passed to the compile. but the spring config won't support tat extra listener. <drools-spring:kbase id="kbase"> <drools-spring:resources> <drools-spring:resource type="DTABLE" source="classpath:myco/matrix_ruletable.xls" > <drools-spring:decisiontable-conf input-type="XLS"/> </drools-spring:resource> </drools-spring:resources> </drools-spring:kbase> I am considering making a patch to support a Matrix style spreadsheet. Which way would you suggest I head (a) add a new "decisionmatrixtable-conf to the schema a a new parser - because they are different (modify droolsjbpm-integration//drools-spring/src/main/java/org/drools/container/spring/namespace/ResourceDefinitionParser.java) (create a new DecisionTableConfiguration for Matrix sheets) (b) add a new input type to the DecisionTable .. (XLS_MATRIX) (c) add the ability to inject a "SheetLisner" as an optional parameter to "decisiontable-conf" (d) other. Something else I noted is that, when you do have a "SheetListener" passed to .compile( … ) you also cannot have a worksheetName ie: compile(stream, inputType, listener) compile(stream, inputType) compile(stream, string) Does that need a little uplift as well ? The assumption that (stream, string) is always an XLS doesn't seem right. regards Ramon Ramon Buckland ra...@thebuckland.com
