      public Observation(double[] obsList, int ID)
      Constructor, creates an instance of observation which contains the values passed through obsList double list.
      Parameters:
      obsList - Elements of observation

  • Method Details

    • getID

      public int getID()

    • setID

      public void setID(int ID)

    • compareTo

      public int compareTo(Object obj)
      Comparable interface method overridden, to allow to sort observations according to sortIndex value
      Specified by:
      compareTo in interface Comparable<Object>
      Parameters:
      obj - element to compare to this instance
      Returns:
      a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object.

    • getIndex

      public double getIndex(int Index) throws ArrayIndexOutOfBoundsException
      Return to Ith element stored in the observation instance
      Parameters:
      Index - element position
      Returns:
      Ith element
      Throws:
      ArrayIndexOutOfBoundsException - Index out of the range allowed

    • setIndex

      public void setIndex(int Index, double val) throws ArrayIndexOutOfBoundsException
      Stores the val value passed in the Index-th element of the instance
      Parameters:
      Index - element position
      val - value to store
      Throws:
      ArrayIndexOutOfBoundsException - Index out of the range allowed

    • getSize

      public int getSize()
      Returns the size ( number of elements ) of the observation
      Returns:
      Size of the observation

    • setSorter

      public void setSorter(int Index) throws ArrayIndexOutOfBoundsException
      Sets up element on which perform compareTo method
      Parameters:
      Index - index of element
      Throws:
      ArrayIndexOutOfBoundsException - if the operation cannot be completed

    • toString

      public String toString()
      Overrides:
      toString in class Object

    • setValid

      public void setValid(boolean b)
      Sets the validity of the observation. This method is used to apply sampling operation without the loss of the original observation and to sync on these values all variables
      Parameters:
      b - validity value

    • isValid

      public boolean isValid()
      Getter
      Returns:
      validity of the observation
