Member Function Documentation

int64_t ns3::RandomDiscPositionAllocator::AssignStreams ( int64_t stream )

virtual

Assign a fixed random variable stream number to the random variables used by this model. Return the number of streams (possibly zero) that have been assigned.

This method must be implement in subclasses.

Parameters

stream first stream index to use

Returns: the number of stream indices assigned by this model

Implements ns3::PositionAllocator.
