This generator assigns addresses sequentially from a provided network address; used in topology code.
static Ipv4Address NextAddress(const Ipv4Mask mask)
Allocate the next Ipv4Address for the configured network and mask.
static void InitAddress(const Ipv4Address addr, const Ipv4Mask mask)
Set the address for the given mask.
static void TestMode()
Used to turn off fatal errors and assertions, for testing.
static Ipv4Address NextNetwork(const Ipv4Mask mask)
Get the next network according to the given Ipv4Mask.
static void Reset()
Reset the networks and Ipv4Address to zero.
static bool AddAllocated(const Ipv4Address addr)
Add the Ipv4Address to the list of IPv4 entries.
static bool IsAddressAllocated(const Ipv4Address addr)
Check the Ipv4Address allocation in the list of IPv4 entries.
static Ipv4Address GetNetwork(const Ipv4Mask mask)
Get the current network of the given Ipv4Mask.
static void Init(const Ipv4Address net, const Ipv4Mask mask, const Ipv4Address addr="0.0.0.1")
Initialise the base network, mask and address for the generator.
static bool IsNetworkAllocated(const Ipv4Address addr, const Ipv4Mask mask)
Check if a network has already allocated addresses.
static Ipv4Address GetAddress(const Ipv4Mask mask)
Get the Ipv4Address that will be allocated upon NextAddress ()
Ipv4 addresses are stored in host order in this class.
