Member Function Documentation

virtual void cWeightedStdDev::clearResult (   )  [virtual]

Clears the results collected so far. Reimplemented from cStdDev.

virtual void cWeightedStdDev::collect (  double  val  )  [inline, virtual]

Collects one value. Reimplemented from cStdDev.

virtual void cWeightedStdDev::collect2 (  double  val, double  weight )  [virtual]

Collects one value with a given weight. Reimplemented from cStatistic.

virtual cObject* cWeightedStdDev::dup (   )  const [inline, virtual]

Creates and returns an exact copy of this object. See cObject for more details. Reimplemented from cStdDev.

virtual void cWeightedStdDev::loadFromFile (  FILE *   )  [virtual]

Reads the object data from a file, in the format written out by saveToFile(). Reimplemented from cStdDev.

virtual double cWeightedStdDev::mean (   )  const [inline, virtual]

Returns the mean of the samples collected. Reimplemented from cStdDev.

virtual void cWeightedStdDev::netPack (  cCommBuffer *  buffer  )  [virtual]

Serializes the object into a PVM or MPI send buffer. Used by the simulation kernel for parallel execution. See cObject for more details. Reimplemented from cStdDev.

virtual void cWeightedStdDev::netUnpack (  cCommBuffer *  buffer  )  [virtual]

Deserializes the object from a PVM or MPI receive buffer Used by the simulation kernel for parallel execution. See cObject for more details. Reimplemented from cStdDev.

cWeightedStdDev& cWeightedStdDev::operator= (  const cWeightedStdDev &  res  )

Assignment operator. The name member doesn't get copied; see cObject's operator=() for more details.

virtual void cWeightedStdDev::saveToFile (  FILE *   )  const [virtual]

Writes the contents of the object into a text file. Reimplemented from cStdDev.

virtual double cWeightedStdDev::variance (   )  const [virtual]

Returns the variance of the samples collected. Reimplemented from cStdDev.

virtual double cWeightedStdDev::weights (   )  const [inline, virtual]

Returns the sum of weights of the samples collected. Reimplemented from cStdDev.
