Passing CRC attributes as a published parameter

Hi Sami,

 

 

I don't think there is a way to pass a user parameter to the attribute list of the CRCCalculator. But you can use the FMEFunctionCaller (or Python / Tcl scripting) to call the @CRC function passing a user parameter as its argument.

 

e.g. assuming that $(CRC_ATTR) is comma separated attribute names:

 

-----

 

@CRC(ATTRIBUTES,$(CRC_ATTR))

 

 

 

See this page to learn more about the @CRC function.

Hi @takashi, how would I include the feature geometry in this function. Would I need to use the GeometryExtractor transformer first? Is this answer still relevant with FME 2018? I can't see any options to select "All Attributes" with the CRCCalculator transformer.

I just discovered the answer... The @CRC function can be altered to accept GEOM as a parameter, or the ALL option can be used to calculate a CRC value on All attributes and geometry.
