FMECurve.snip() function deprecation

Interestingly, the current fmeobjects documentation does not mention the deprecation of the snip() method:

https://docs.safe.com/fme/html/fmepython/api/fmeobjects/geometry/_curves/fmeobjects.FMECurve.html#fmeobjects.FMECurve.snip

Neither does the FME deprecations page: https://support.safe.com/hc/en-us/articles/25407729702029-FME-Deprecations

Maybe reach out to Safe support for up to date information.

Try something like this, using the FMEGeometryTools.snip() method as suggested in the warning:

import fmeobjects, math

class LineDivider(object):
    def __init__(self):
        self.geomTools = fmeobjects.FMEGeometryTools()

    def input(self, feature):
        is3D = (feature.getAttribute('__linedivider.dim') == '3D')
        mode = feature.getAttribute('__linedivider.mode')
        value = float(feature.getAttribute('__linedivider.value'))
        output = feature.getAttribute('__linedivider.output')
        for attr in ['dim', 'mode', 'value', 'output']:
            feature.removeAttribute('__linedivider.' + attr)
        coordSys = feature.getCoordSys()
        outputLines = output.startswith('Lines')
        outputPoints = output.startswith('LinesAndPoints') or output.startswith('Points')
        outputEndNodes = outputPoints and not output.endswith('ExceptEndNodes')
        length = float(feature.performFunction('@Length(3)') if is3D else feature.performFunction('@Length(2)'))
        numLines = int(round(value) if mode == 'ToNumber' else math.ceil(length / value))
        segLen = value if mode == 'ToLength' else length / numLines

        sourceGeom = feature.getGeometry()

        for (beg, end) in [(i * segLen, (i + 1) * segLen) for i in range(numLines)]:
            snipEnd = end if end < length else -1
            snipped = self.geomTools.snip(
                sourceGeom, fmeobjects.SNIP_DISTANCE, is3D, beg, snipEnd
            )
            if outputLines:
                line = feature.cloneAttributes()
                line.setGeometry(snipped)
                line.setCoordSys(coordSys)
                self.pyoutput(line)
            if outputPoints and (0.0 < beg or outputEndNodes):
                point = feature.cloneAttributes()
                point.setGeometry(snipped.getStartPoint())
                point.setCoordSys(coordSys)
                self.pyoutput(point)

        if outputEndNodes:
            point = feature.cloneAttributes()
            point.setGeometry(sourceGeom.getEndPoint())
            point.setCoordSys(coordSys)
            self.pyoutput(point)

    def close(self):
        pass

Caveat emptor: I haven’t tested it myself :-)

Note, the python you’ve posted here is not the same as the python in the current iteration of the transformer (same error though).

Does the warning actually cause the job to fail if run on flow?
