Examples of org.drools.decisiontable.parser.DefaultRuleSheetListener

org.drools.decisiontable.parser.DefaultRuleSheetListener
@author Shaun Addison Michael Neale Define a ruleset spreadsheet which contains one or more decision tables. Stay calm, deep breaths... this is a little bit scary, its where it all happens. A table is identifed by a cell beginning with the text "RuleTable". The first row after the table identifier defines the column type: either a condition ("C") or consequence ("A" for action), and so on. The second row contains ObjectType declarations (optionally, or can be left blank). If cells are merged, then all snippets below the merged bit will become part of the same column as seperate constraints. The third row identifies the java code block associated with the condition or consequence. This code block will include a parameter marker for the attribute defined by that column. The third row is a label for the attribute associated with that column. All subsequent rows identify rules with the set.
