  • Method Summary

    Modifier and Type
    Method
    Description
    default double
    getAsDouble()
     
    default int
    getDimension()
    Get the sample vector dimension.
    default double[]
    getNext()
    Get the next sample vector of dimension n, where n is getDimension.
    double
    nextDouble()

  • Method Details

    • nextDouble

      double nextDouble()
      Thread safe implementation returning the next double value of this random number generator.
      Returns:
      The next double value of this random number generator

    • nextDoubleFast

      default double nextDoubleFast()
      Possibly faster, non-thread safe implementation returning the next double value of this random number generator. The user of this method has to ensure synchronization if this generator is shared by different threads.
      Returns:
      The next double value of this random number generator

    • getNext

      default double[] getNext()
      Description copied from interface: RandomNumberGenerator
      Get the next sample vector of dimension n, where n is getDimension. An implementation has to be thread safe.
      Specified by:
      getNext in interface RandomNumberGenerator
      Returns:
      The next sample vector of dimension n, where n is getDimension.

    • getDimension

      default int getDimension()
      Description copied from interface: RandomNumberGenerator
      Get the sample vector dimension.
      Specified by:
      getDimension in interface RandomNumberGenerator
      Returns:
      The sample vector dimension n.

    • getAsDouble

      default double getAsDouble()
      Specified by:
      getAsDouble in interface DoubleSupplier
