[kepler-users] Query with the Expression actor

[hriyer at ncsu.edu]

Hi,

I had a query regarding the expression actor. Consider a scenario, where I
have an expression actor with 2 input ports, a1 and a2, and one output
port. The expression in the actor simply says a1, What is that supposed to
mean? a1 and a2 given as inputs are simply some strings that represent a
filename or something similar. So if the expression in the Expression
actor is the name of the input port, what does that mean?

Thanks,
Harini
