◆ getIPv6LeaseForDelete()

Lease6Ptr isc::lease_cmds::LeaseCmdsImpl::getIPv6LeaseForDelete ( const Parameters & parameters ) const

Convenience function fetching IPv6 address to be used to delete a lease.

The returned parameter depends on the query_type value stored in the passed object. Note that the HW address is not allowed and this query type results in an exception. If the query type is of the address type, the address is returned. If the type is set to DUID, this function will try to find the lease for this DUID and return the corresponding address.

Parameters

parameters parameters extracted from the command.

Returns: Lease of the lease to be deleted.

Exceptions

InvalidParameter	if the DUID is not found when needed to find the lease or if the query type is by HW address.
InvalidOperation	if the query type is unknown.

See Parameters class for detailed description of what is expected in the args structure.

Parameters

v6	whether addresses allowed are v4 (false) or v6 (true)
