  • Constructor Details

    • GPVector

      public GPVector(GPVector e)

    • GPVector

      public GPVector(GVector v)
      Creates a new GPVector based on the GVector passed as argument.
      Note: this constructor uses a COPY of the vector, so if you need to change some parameters of the vector, you'll need to use:
      Parameters:
      v - the vector used as base
      Throws:
      IllegalArgumentException - if v is null

    • GPVector

      public GPVector(int x, int y, double l, double a)
      Creates a new GPVector
      Parameters:
      x - x coordinate of the application point of the vector
      y - y coordinate of the application point of the vector
      l - vector modulus
      a - vector angle (in degrees)

    • setModulus

      public void setModulus(double x, double y)
      Sets a new modulus and argument to the main vector based on the modulus of the orthogonal components
