public interface RandomVariableRVNOps<T extends Number,RV extends RandomVariableOps<T>> extends RandomVariableRVOps<T,RV>
Interface for random variables that generates another random variable that in turn generates numbers. The type parameter T indicates the type of number and the type parameter RV indicates the type of the random variable that generates the number.

  • Method Details

    • getMinimumRV

      T getMinimumRV()
      Get the minimum value that will be set for random variables that the current object generates.
      Returns:
      the minimum value

    • getMaximumRV

      T getMaximumRV()
      Get the maximum value that will be set for random variables that the current object generates.
      Returns:
      the maximum value.

    • getMinimumClosed

      Boolean getMinimumClosed()
      Determine if a random variable's lower bound can be generated. The value returned applies to the bound that will be set for the random numbers that this class generates.
      Specified by:
      getMinimumClosed in interface RandomVariableOps<T extends Number>
      Returns:
      true if it can be generated; false if it cannot be generated; null if this cannot be determined

    • getMaximumClosed

      Boolean getMaximumClosed()
      Determine if a random variable's upper bound can be generated. The value returned applies to the bound that will be set for the random numbers that this class generates.
      Specified by:
      getMaximumClosed in interface RandomVariableOps<T extends Number>
      Returns:
      true if it can be generated; false if it cannot be generated; null if this cannot be determined

    • next

      RV next() throws RandomVariableException
      Get the next value for a random variable.
      Specified by:
      next in interface RandomVariableOps<T extends Number>
      Returns:
      the next value (a random variable)
      Throws:
      RandomVariableException - a failure occurred while attempting to set a range restriction

    • setMinimum

      void setMinimum(T min, boolean closed) throws UnsupportedOperationException, IllegalArgumentException
      Set the minimum value for a random variable. The minimum value will be set for the random variable returned by a call to next()
      Parameters:
      min - minimum value.
      closed - true if the minimum value is part of the range; false if it is a lower bound on the range
      Throws:
      UnsupportedOperationException - the random variable's type does not have an order imposed on it or the operation is not supported for implementation reasons
      IllegalArgumentException - an argument is out of range

    • setMaximum

      void setMaximum(T max, boolean closed) throws UnsupportedOperationException, IllegalArgumentException
      Set the maximum value for a random variable. The maximum value will be set for the random variable returned by a call to next()
      Parameters:
      max - maximum value.
      closed - true if the minimum value is part of the range; false if it is a lower bound on the range
      Throws:
      UnsupportedOperationException - the random variable's type does not have an order imposed on it or the operation is not supported for implementation reasons
      IllegalArgumentException - an argument is out of range

    • tightenMinimum

      void tightenMinimum(T min, boolean closed) throws UnsupportedOperationException, IllegalArgumentException
      Set the manimum value for a random variable, provided the new value is higher than the previous value.
      Parameters:
      min - minimum value.
      closed - true if the minimum value is part of the range; false if it is a lower bound on the range
      Throws:
      UnsupportedOperationException - the random variable's type does not have an order imposed on it or the operation is not supported for implementation reasons
      IllegalArgumentException - an argument is out of range

    • tightenMaximum

      void tightenMaximum(T max, boolean closed) throws UnsupportedOperationException, IllegalArgumentException
      Set the maximum value for a random variable, provided the new value is lower than the previous value.
      Parameters:
      max - maximum value.
      closed - true if the minimum value is part of the range; false if it is a lower bound on the range
      Throws:
      UnsupportedOperationException - the random variable's type does not have an order imposed on it or the operation is not supported for implementation reasons
      IllegalArgumentException - an argument is out of range
