Glad to help :)

Okay you are my hero Alok !
with your approach looping 10 times on this function went
from 1min5sec to 6sec !
thanks a lot !

Thanks Matt !
Interesting solution Alok, my issue is not the 2sec that it
takes to perform the seach but that I am looping on this
method about 20 times... so it makes sense to try something
like that ! I'll give it a try right now !

Maybe globally store the expressions with
their params in a hash (dictionary in Python)
and then do the reverse look up. Will not run faster but will save you
time for each call to getExpressionsDrivenByParameter()
In this case:
PARAM_EXPR_DICT = {}
for expr in Application.FindObjects(None,
"{12723EB2-7DDB-11D0-A57F-00A0C91412DE}"):
ports = expr.InputPorts
if not ports.Count:
continue
for port in in
ports :
paramName =
port.Target2.FullName
if not
PARAM_EXPR_DICT.has_key(paramName):
PARAM_EXPR_DICT[paramName] = []
PARAM_EXPR_DICT[paramName].append(expr)
Then you can test it for parameter simply by:
def getExpressionsDrivenByParameter( param ):
return (PARAM_EXPR_DICT[param.FullName] if
PARAM_EXPR_DICT.has_key(param.Name) else None)

Hi guys,
I was wondering what is your technique
to get all the expressions driven by a
parameter.
I'm trying to find the fastest way to
do it.
here is my code :
def
getExpressionsDrivenByParameter( param
):
allExpressions
= xsi.FindObjects(None,
"{12723EB2-7DDB-11D0-A57F-00A0C91412DE}")
result
= []
for
exp in allExpressions:
for
port in exp.InputPorts:
if
port.Target2.IsEqualTo(param) and
exp.OutputPorts.Count:
result.append(exp)
break
return
result
With around 5000 expressions in my
scene it takes about 2sec to get the
result. Anyone got a faster solution ?
cheers,
Jeremie
