Hi all,
It is possible to find in a "matched rule" (A) a target model
element (by resolveTemp) created by a "called rule" called by
another "matched rule" (B) ?
thx,
Ben.

Hi Ben,
No, it is not possible as called rule are not matched !! You must use
matched rule or lazy rule (restrictions exist in this case).

Hi Mikael,
Thx you for your response. In fact, my concrete problem is the fallowing :
rule A2B {
from MMa!A
to
..... -- target elements creation for all A
do {
if ( A.isXXX ) {
thisModule.myCalledRule(A) -- target elements creation when A is XXX
}
}
}
And now, i would like to find target elements created when A is XXX in another
rule.
Indeed, i can use two matched rule (A_WhichIsXXX2B and A_WhichIsNotXXX2B) but
i repeat all the common part :(
have you got some solutions ?
Regards,
ben.

Thx you for your help Mikael.
I resolve my problem by the use of rule inheritance.

Hi Benoit,
I'm glad to see that you solved your problem.
There are restrictions when you have multiple lazy rules matching the
same model element: ATL is not able to determine which one has to be
selected.

Mikael

Hi Mikael,
In my work, I've one lazy rule called by one matched rule (A).
In another matched rule (B), I try to find the target element created
by the lazy rule.
I've an execution error :
"message: ERROR: could not find operation including on Module
having supertypes: [OclAny]"
Have you got an example with a lazy rule called by a first matched rule
and a second matched rule which use resolveTemp to find the target element
created by the lazy rule ?
Regards,
Ben.

Hello Benoit,
It is possible that resolveTemp does not always work correctly with lazy
rules, I will have to look into this.
However, there is a relatively simple way to make this work: splitting
the lazy rule (see example below).
If you have something like:
rule A {
from
s : MMa!A
to
t : MMb!A (
b <- thisModule.B(s.b),
-- may not work, and apparently does not
-- work in your case
c <- thisModule.resolveTemp(s.b, 't2')
)
}
-- Note that referring to several target elements of a lazy rule
-- mostly makes sense when this rule is *unique*, otherwise it would
-- mean invoking the rule once again.
unique lazy rule B {
from
s : MMa!B
to
t : MMb!B (
c <- t2
),
t2 : MMb!C
}
You may rewrite it into:
rule A {
from
s : MMa!A
to
t : MMb!A (
b <- thisModule.B_1(s.b),
c <- thisModule.B_2(s.b)
)
}
unique lazy rule B_1 { -- or B2B
from
s : MMa!B
to
t : MMb!B (
c <- thisModule.B_2(s)
)
}
unique lazy rule B_2 { -- or B2C
from
s : MMa!B
to
t : MMb!C
}
