bool ns3::SeedManager::CheckSeed |
( |
uint32_t |
seed | ) |
|
|
static |
Check if seed value is valid if wanted to be used as seed.
- Returns:
- true if valid and false if invalid
uint32_t ns3::SeedManager::GetRun |
( |
void |
| ) |
|
|
static |
- Returns:
- the current run number
- See also:
- SetRun
uint32_t ns3::SeedManager::GetSeed |
( |
| ) |
|
|
static |
Get the seed value.
- Returns:
- the seed value
Note: returns the first of the six seed values used in the underlying RNG
References NS_ASSERT.
void ns3::SeedManager::SetRun |
( |
uint32_t |
run | ) |
|
|
static |
Set the run number of simulation.
int N = atol(argv[1]);
UniformVariable x(0,10);
ExponentialVariable y(2902);
In this example, N could successivly be equal to 1,2,3, etc. and the user would continue to get independent runs out of the single simulation. For this simple example, the following might work:
./simulation 0
...Results for run 0:...
./simulation 1
...Results for run 1:...
void ns3::SeedManager::SetSeed |
( |
uint32_t |
seed | ) |
|
|
static |
set the seed it will duplicate the seed value 6 times
UniformVariable x(2,3);
ExponentialVariable y(120);
- Parameters:
-
seed | Note, while the underlying RNG takes six integer values as a seed; it is sufficient to set these all to the same integer, so we provide a simpler interface here that just takes one integer. |
