    • initialize

      public boolean initialize​(java.lang.String file)
      Description copied from interface: SimulationWriter
      Initializes the simulation writing.
      Specified by:
      initialize in interface SimulationWriter<U extends java.io.Serializable,​I extends java.io.Serializable,​P>
      Parameters:
      file - the name of the file where we want to store the simulation.
      Returns:
      true if everything went OK, false if something failed while configuring the writer.

      Parameters:
      simulation - the simulation.
      Returns:
      true if everything went OK, false if something failed while writing.
