FW: [rules-users] Variable assignment in DSL
by Shyam, Pallav (MSCIBARRA)
Hi Matt,
Going by the below example I have come across a senario which seems like
a bug to me.
Here is my dsl
[condition][]{varname} is a Volume where {constraints}={varname} :
RawVolumeTs ( where {constraints} )
[condition][]where {attr} is "{value}"={attr} == "{value}"
[condition][]and {attr} is {value}=, {attr} == {value}
Now,
v1 is a Volume where status is "NV" and sourceId is 2
Translates to
v1 : RawVolumeTs (status == "NV", sourceId == 2 )
Only when I put an extra space after and. Otherwise the ending quote of
"NV" get cut-off resulting in
v1 : RawVolumeTs (status == "NV, sourceId == 2 )
Also
v1 is a Volume where status is "NV" and sourceId is 2 and volume is
1000
Give a totally incorrect drl
v1 : RawVolumeTs (status == "NV", sourceId == 2 and volume is 1000 )
Thanks
Pallav

how about changing the first line of your DSL map to...
[condition][]{varname} is a Volume where {constraints} = {varname} :
RawVolumeTs (where {constraints} )
That way, your DSL would read...
rule "RT(2) against FT(32)"
when
V1 is a Volume where status is "NA" and sourceId is "ABC"
V2 is a Volume where status is "NA" and sourceId is "XYZ"
then
end
and the resulting DRL would read...
rule "RT(2) against FT(32)"
when
V1 : RawVolumeTs (status == "NA", sourceId == "ABC")
V2 : RawVolumeTs (status == "NA", sourceId == "XYZ")
then
End
