Description
| Class Summary | |
|---|---|
| Bucket | A Bucket defines an atomic value for a Dimension of a decision table. |
| BucketSet | A BucketSet is the set of values in a Dimension of a decision table. |
| BucketTable | A list of Buckets in a BucketSet. |
| Conflict | A Conflict is 2 rules with overlapping Dimension values in all dimensions, different actions, and no reference from one to the other in its noConflict, runBefore, or override lists. |
| Dimension | A Dimension defines a top-level ANDed term in the condition part of every rule in a decision table. |
| DimensionNode | A DimensionNode stores the dimension values for a "cell" in the decision table. |
| DimensionNodeTable | A list of DimensionNodes in the same Dimension. |
| DimensionTable | An ordered list of Dimensions in the decision table. |
| DTAction | A DTAction is an action that may be selected by any rule in the decision table, optionally with different parameters per rule. |
| DTActionNode | A DTActionNode tells each DTRule how to interpret its DTAction. |
| DTActionNodeTable | A list of DTActionNodes per DTAction. |
| DTActionTable | An ordered list of DTActions in the decision table. |
| DTComponentTable<T extends RuleComponent> | |
| DTRule | A DTRule contains conflict resolution information and provides methods for accessing the DimensionNodes and DTActionNodes for the rule. |
| DTRuleTable | A list of DTRules in the decision table. |
| Gap | A Gap specifies a missing rule using a DimensionNode (sibling) that is missing a sibling in order to cover all the Buckets in the sibling Dimension. |
| RuleSheet | A RuleSheet represents a decision table. |
A decision table is a RuleSheet and contents: DTRules, Dimensions, and DTActions.
Dimensions contain DimensionNodes, and DTActions contain DTActionNodes. DimensionNodes are linked together in a tree. DTRules refer to a DimensionNode per Dimension, and to a DTActionNode per DTAction.
The decision table package does not impose a particular layout. In fact, the "table" could even be represented as a tree or an N-dimensional pivot table.
One possible layout is shown below:
|
|
|
Rule1 | Rule2 | Rule3 |
|---|---|---|---|---|
|
Dimension1
|
age
|
[30..70]
|
<30, >70
|
|
|
Dimension2
|
gender
|
M
|
F
|
-
|
|
DTAction1
|
set risk
|
medium
|
low
|
high
|
DimensionNodes are in grey, and DTActionNodes are in yellow.
