EMF operation invocation in an ATL module [message #1075395]

Hi there,

rule rule_getDevice{
from
a: source!DeviceItem
to
p:target!Device(
name <- a.Name,
s7DeviceReference<-a.DeviceReference,
isSelectedWithinStep7 <-a.stringToBool(a.IsSelected)
)

}

stringToBool() defined in the source EMF meta-model. I set the Operation Reflection feature of the gen model to True.

I get the following error, When I run this transformation using ATL Run configuration,

org.eclipse.m2m.atl.engine.emfvm.VMException: Operation not found: IN!<unnamed>.stringToBool(java.lang.String)

Any help is appreciated.

Cheers,
Kosala

Hello,

Invoking such Java-implemented operations is generally not a recommended practice in ATL.
However, the refInvokeOperation operation allows to do so when really needed.

Hi Hugo,

Thanks. Do you have any clue how to use refInvokeOperation in the above example?

isSelectedWithinStep7 <-a.stringToBool(a.IsSelected)

Cheers,

As explained in the manual, something like: a.refInvokeOperation('stringToBool',Sequence{a.IsSelected})

Best regards,
