Variable assignment in DSL
by Shyam, Pallav (MSCIBARRA)
I have a DSL
[condition][]There is a Volume where {constraints}=v : RawVolumeTs (
where {constraints} )
[condition][]where {attr} is "{value}"={attr} == "{value}"
[condition][]and {attr} is "{value}"=, {attr} == "{value}"
And here is my business rule using the above dsl(the dslr file)
dialect "java"
expander volume.dsl
rule "RT(2) against FT(32)"
when
There is a Volume where status is "NA" and sourceId is
"ABC"
There is a Volume where status is "NA" and sourceId is
"XYZ"
then
end
And here is the translated DRL
dialect "java"
rule "RT(2) against FT(32)"
when
v : RawVolumeTs (status == "NA", sourceId == "ABC")
v : RawVolumeTs (status == "NA", sourceId == "XYZ")
then
End
In the above example both the instances of RawVolumeTs as assigned to
variable v.
How do I write a dsl that each of these RawVolumeTs instances get
assigned to different variables.
For example:
The first statement -- There is a Volume where status is "NA" and
sourceId is "ABC" -- should assign it to variable V1
And the second statement -- There is a Volume where status is "NA" and
sourceId is "XYZ" -- should assign it to variable V2.
