Constructor & Destructor Documentation

CSubNet() [1/4]

CSubNet::CSubNet

(

)

Construct an invalid subnet (empty, Match() always returns false).

Definition at line 914 of file netaddress.cpp.

CSubNet() [2/4]

CSubNet::CSubNet	(	const CNetAddr &	addr,
		uint8_t	mask
	)

Construct from a given network start and number of bits (CIDR mask).

Parameters

[in]	addr	Network start. Must be IPv4 or IPv6, otherwise an invalid subnet is created.
[in]	mask	CIDR mask, must be in [0, 32] for IPv4 addresses and in [0, 128] for IPv6 addresses. Otherwise an invalid subnet is created.

Definition at line 920 of file netaddress.cpp.

Here is the call graph for this function:

CSubNet() [3/4]

CSubNet::CSubNet	(	const CNetAddr &	addr,
		const CNetAddr &	mask
	)

Construct from a given network start and mask.

Parameters

[in]	addr	Network start. Must be IPv4 or IPv6, otherwise an invalid subnet is created.
[in]	mask	Network mask, must be of the same type as addr and not contain 0-bits followed by 1-bits. Otherwise an invalid subnet is created.

Definition at line 961 of file netaddress.cpp.

Here is the call graph for this function:

CSubNet() [4/4]

CSubNet::CSubNet ( const CNetAddr &  addr )

explicit

Construct a single-host subnet.

Parameters

[in]

addr

The sole address to be contained in the subnet, can also be non-IPv[46].
