Rule Examples
This section contains examples of how to use the eConfigurator Rule Assembly Language to create rules. Some of the rules show item names consisting of both the product name and its configuration ID (Cfg ID). Basic Rules
The following table shows how create basic rules using Rule Assembly Language.
|
|
A requires B noncumulatively |
req(A, B)
|
A requires B cumulatively |
inc(A,B)
|
A excludes B |
excl(A,B)
|
A provides the amount B to C |
inc(*(A,B),C)
|
A consumes the amount B from C |
inc(*(A,-(B)),C)
|
A's minimum quantity is B, enforced |
>=(A,B)
|
A's maximum quantity is B, enforced |
<=(A,B)
|
A recommends B |
rec(req(A,B))
|
Boolean and Comparison Operators
The following table shows how to create rules using Boolean and comparison operators.
|
|
A AND B =C |
==(and(A,B),C)
|
A OR B = C |
==(or(A,B),C)
|
NOT (A = B) |
xor(A,B)
|
(A < B) requires C |
req(<(A,B),C)
|
(A <= B) requires C |
req(<=(A,B),C)
|
(A = B) requires C |
req(==(A,B),C)
|
(A != B) requires C |
req(!=(A,B),C)
|
(A >=B) requires C |
req(>=(A,B),C)
|
(A >B) requires C |
req(>(A,B),C)
|
(A + B) contributes to C |
inc(+(A,B),C)
|
(A - B) contributes to C |
inc(-(A,B),C)
|
(A * B) contributes to C |
inc(*(A,B),C)
|
(A/B) contributes to C |
inc(/(A,B),C)
|
(A MIN B) contributes to C |
inc(min(A,B),C)
|
(A MAX B) contributes to C |
inc(max(A,B),C)
|

|
|
Constrain |
con(>(Item A),1)) |
Constrain (quantity of
Item A> 1) to be true. |
Constrain Conditionally |
if(>(Item A), 1), >=
(Item B), 2), excl(Item C, Item D)) |
When (quantity of
Item A> 1)(quantity of Item B >= 2), otherwise Selection of Item C excludes selection of
Item D. |
Constrain Product Quantity |
==(Item A, 2) |
The quantity of Item A = 2. |
Consume |
inc(*(Item A), -(1)), Resource B) |
Each Item A consumes 1 from Resource B. |
Exclude |
excl(Item A, Item B) |
Selection of Item A excludes selection of Item B. |
Exclude List |
excl(Item A, Item B, Item C)) |
Item A excludes (selection of Item B, selection of Item C). |
Message |
msg(>(Item A, 1)) |
When (Item A > 1), display this rule's description. |
Preference |
prefer(Item A, 1) |
When possible, constrain Item A is selected to be true with a priority of 1. |
Provide |
inc(*(Item A), 1),
Resource B) |
Each Item A provides 1 to Resource B. |
Recommends |
chk(req(Item A, Item B), "Item B is recommended") |
Selection of Item A recommends selection of at least one Item B by displaying "Item B is recommended". |
Requires |
req(Item A, Item B) |
Item A requires Item B. |
Requires (Mutual) |
eqv(Item A, Item B) |
Item A requires Item B AND Item B requires Item A. |
Constrain Attribute Value |
==(@.[Class A]
([Item B]).[Day], "Monday") |
The attribute Class A
"Item B" Attribute C = Monday. |
