Constructor & Destructor Documentation

Hold() [1/2]

anonymous_namespace{sample-show-progress.cc}::Hold::Hold ( Time  wait, Time  interval  )

inline

Create a Hold with mean inter-event time wait, changing workload every interval.

Parameters

wait	The mean inter-event time.
interval	How often to change work load. This should be an order of magnitude larger than wait.

Definition at line 64 of file sample-show-progress.cc.

Hold() [2/2]

anonymous_namespace{sample-show-progress.cc}::Hold::Hold ( Ptr< RandomVariableStream >  rng )

inline

Create a hold with a specified random number generator for the wait time.

The RNG value will be interpreted as seconds.

Parameters

rng	The random variable generator to use for the inter-event time.

Definition at line 78 of file sample-show-progress.cc.

Member Function Documentation

Event()

void anonymous_namespace{sample-show-progress.cc}::Hold::Event ( void  )

inline

The Hold event.
