RuleMatrixSheetListener (Drools 4.0.0.11754MR2 API) - JBoss RULES 4.0.0.11754MR2 API 英文版文档
org.drools.decisiontable.parser
Class RuleMatrixSheetListener
java.lang.Object
org.drools.decisiontable.parser.DefaultRuleSheetListener
org.drools.decisiontable.parser.RuleMatrixSheetListener
- All Implemented Interfaces:
- RuleSheetListener, SheetListener
public class RuleMatrixSheetListener
- extends DefaultRuleSheetListener
- Author:
- Steven Williams Michael Neale
Define a ruleset spreadsheet which contains a matrix style decision tables.
This is an example of a custom RuleSheetListener. It differs from the standard
decision table in the following ways:
- AgendaGroup property so that all rules fall within the same agenda-group
- Precondition property which specifies a condition that is always included
if a rule is being generated
- Action property. Each cell within the decision table causes this action
to be triggered
- HorizontalCondition property. Each column header in the matrix
applies this condition
- VerticalCondition property. Each row header in the matrix applies this
condition
A table is identifed by a cell beginning with the text "RuleTable".
The cells after RuleTable in the same row identify the Horizontal Conditions.
The cells after RuleTable in the same column identify the Vertical Conditions.
The cells with the matrix identify the actions.
Wherever an action cell exists for a Vertical/Horizontal condition intersection
the following rule is created:
rule "rule_row_col"
agenda-group AgendaGroup
when
Precondition
VerticalCondition
HorizontalCondition
then
Action
end

RuleMatrixSheetListener
public RuleMatrixSheetListener()
newCell
public void newCell(int row,
int column,
String value,
int mergedColStart)
- Description copied from interface:
SheetListener
- Enter a new cell.
Do NOT call this event for trailling cells at the end of the line.
It will just confuse the parser. If all the trailing cells are empty, just
stop raising events.
- Specified by:
newCell
in interface SheetListener
- Overrides:
newCell
in class DefaultRuleSheetListener
- Parameters:
row
- the row numbercolumn
- the column alpha character labelvalue
- the string value of the cell
newRow
public void newRow(int rowNumber,
int columns)
- Description copied from interface:
SheetListener

postInitRuleTable
protected void postInitRuleTable(int row,
int column,
String value)
- Description copied from class:
DefaultRuleSheetListener
- Called after rule table initialisation. Subclasses may
override this method to do additional processing.
- Overrides:
