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)
Alok.

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
