[kepler-dev] [kepler-users] SDF Firing Order

[Dan Higgins]

Hi Ken,
    The error you report was occurring in the Kepler nightly build over 
the weekend and then disappeared. I assume it was a bug fixed in one of 
the recent Ptolemy code updates. I suggest you download a new version of 
the Ptolemy.

   

ptolemy.actor.lib.io is a package in Ptolemy, not a class. LineWriter is a class in that package and FileWrite extends that class. Any extension runs some of the code in the class it is extended from. So Kepler is running org.geon.FileWrite whihch inherits most of its methods from LineWriter. You can always run the LineWriter actor directly if you do not need the output port added in FileWrite.
