Detailed Description

Base Memfile derivation of the statistical lease data query.

This class provides the functionality such as results storage and row fetching common to fulfilling the statistical lease data query.

Constructor & Destructor Documentation

isc::dhcp::MemfileLeaseStatsQuery::MemfileLeaseStatsQuery ( )

inline

Constructor for all subnets query.

Definition at line 263 of file memfile_lease_mgr.cc.

isc::dhcp::MemfileLeaseStatsQuery::MemfileLeaseStatsQuery ( const SubnetID & subnet_id )

inline

Constructor for single subnet query.

Parameters

subnet_id ID of the desired subnet

Definition at line 270 of file memfile_lease_mgr.cc.

isc::dhcp::MemfileLeaseStatsQuery::MemfileLeaseStatsQuery	(	const SubnetID &	first_subnet_id,
		const SubnetID &	last_subnet_id
	)

inline

Constructor for subnet range query.

Parameters

first_subnet_id	ID of the first subnet in the desired range
last_subnet_id	ID of the last subnet in the desired range

Definition at line 278 of file memfile_lease_mgr.cc.

virtual isc::dhcp::MemfileLeaseStatsQuery::~MemfileLeaseStatsQuery ( )

inlinevirtual

Destructor.

Definition at line 283 of file memfile_lease_mgr.cc.

Member Function Documentation

virtual bool isc::dhcp::MemfileLeaseStatsQuery::getNextRow ( LeaseStatsRow & row )

inlinevirtual

Fetches the next row in the result set.

Once the internal result set has been populated by invoking the the start() method, this method is used to iterate over the result set rows. Once the last row has been fetched, subsequent calls will return false.

Parameters

row	Storage for the fetched row

Returns: True if the fetch succeeded, false if there are no more rows to fetch.

Reimplemented from isc::dhcp::LeaseStatsQuery.

int isc::dhcp::MemfileLeaseStatsQuery::getRowCount ( ) const

inline

Returns the number of rows in the result set.
