    public class DefaultRuleSheetListener
extends Object
implements RuleSheetListener
    An object of this class is prepared to receive calls passing it the contents of a spreadsheet containing one or more decision tables. Each of these tables is then expanded into a set of similar rules, varying to a degree with respect to the patterns and actions. A "rule set" starts with some overall definitions such as imports, globals, functions and queries. 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 pattern of the condition or an action for the consequence, or an attribute. The second row contains optional pattern type declarations. If cells in this row are merged, then all snippets below the merged stretch become part of the same pattern, as separate constraints. The third row identifies the java code block associated with the condition or consequence. This code block should include one or more parameter markers for the insertion of values defined in cells of that column. The third row is available for comments on the purpose of the column. All subsequent rows identify rules with the set, providing values to be inserted where there are markers in the code snippets defined in the third row, or for the attribute identified by the column header. href="mailto:michael.neale@gmail.com"> Michael Neale
