Member Function Documentation

Pool4Ptr isc::dhcp::Pool4::create	(	const isc::asiolink::IOAddress &	first,
		const isc::asiolink::IOAddress &	last
	)

static

Factory function for creating an instance of the Pool4.

This function should be used to create an instance of the pool within a hooks library in cases when the library may be unloaded before the object is destroyed. This ensures that the ownership of the object by the Kea process is retained.

Parameters

first	the first address in a pool
last	the last address in a pool

Returns: Pointer to the Pool4 instance.

Definition at line 92 of file pool.cc.

Pool4Ptr isc::dhcp::Pool4::create	(	const isc::asiolink::IOAddress &	prefix,
		uint8_t	prefix_len
	)

static

Factory function for creating an instance of the Pool4.

This function should be used to create an instance of the pool within a hooks library in cases when the library may be unloaded before the object is destroyed. This ensures that the ownership of the object by the Kea process is retained.

Parameters

prefix	specifies prefix of the pool.
prefix_len	specifies length of the prefix of the pool.

Returns: Pointer to the Pool4 instance.

Definition at line 97 of file pool.cc.

data::ElementPtr isc::dhcp::Pool4::toElement ( ) const

virtual

Unparse a Pool4 object.

Returns: A pointer to unparsed Pool4 configuration.

Reimplemented from isc::dhcp::Pool.

Definition at line 134 of file pool.cc.
