    • parse

      public void parse() throws IOException
      Description copied from interface: SubParser
      Method each sub parser is required to use to begin parsing their respective commands.
      Specified by:
      parse in interface SubParser
      Throws:
      IOException - Invalid input.

    • recParser

      private HashMap<String,String> recParser(int arg, HashMap<String,String> map) throws IOException
      Recursively parse through the command.
      Parameters:
      arg - Index of command argument to reference.
      map - Hashmap to store identify information of the given command.
      Returns:
      The Hashmap.
      Throws:
      IOException

    • passThroughEquation

      private void passThroughEquation(cs350s22.support.Identifier id)
      Creates mapper id that does not remap the raw value. This is equivalent to CREATE MAPPER id EQUATION SCALE 1.
      Parameters:
      id - Name of the mapper object to be created.

    • scaleEquation

      private void scaleEquation(cs350s22.support.Identifier id, int value)
      Creates mapper id that remaps the raw value by the linear coefficient value.
      Parameters:
      id - Name of the mapper object to be created.
      value - The linear coefficient value passed to the mapper.

    • normalizeEquation

      private void normalizeEquation(cs350s22.support.Identifier id, int valueOne, int valueTwo)
      Creates mapper id that remaps the raw value onto a percentage scale as defined by the lower limit valueOne and upper limit valueTwo.
      Parameters:
      id - Name of the mapper object to be created.
      valueOne - Lower limit of the mapper.
      valueTwo - Upper limit of the mapper.

    • linearInterpolation

      private void linearInterpolation(cs350s22.support.Identifier id, cs350s22.support.Filespec filename) throws IOException
      Creates mapper id that remaps the raw value based on the comma-delimited interpolation table defined in string. Each row defines a point in the two-dimensional graph. The first value is the raw sensor value; the second is its mapped value. LINEAR mode does linear interpolation; SPLINE does a smoother nonlinear interpolation.
      Parameters:
      id - Name of the mapper object to be created.
      filename - Name of the file to be used.
      Throws:
      IOException - Invalid input.

    • splineInterpolation

      private void splineInterpolation(cs350s22.support.Identifier id, cs350s22.support.Filespec filename) throws IOException
      Creates mapper id that remaps the raw value based on the comma-delimited interpolation table defined in string. Each row defines a point in the two-dimensional graph. The first value is the raw sensor value; the second is its mapped value. LINEAR mode does linear interpolation; SPLINE does a smoother nonlinear interpolation.
      Parameters:
      id - Identifier for the command type.
      filename - Name of the file to be used.
      Throws:
      IOException - Invalid input.
