Detailed Description

Common CQL and Lease Data Methods.

The CqlLease4Exchange and CqlLease6Exchange classes provide the functionality to set up binding information between variables in the program and data extracted from the database. This class is the common base to both of them, containing some common methods.

Member Function Documentation

virtual void isc::dhcp::CqlLeaseExchange::createBindForSelect	(	AnyArray &	data,
		StatementTag	statement_tag = `NULL`
	)

overridepure virtual

Create BIND array to receive C++ data.

Used in executeSelect() to retrieve from database

Parameters

data	array of bound objects representing data to be retrieved
statement_tag	prepared statement being executed; defaults to an invalid index

Implements isc::db::CqlExchange.

Implemented in isc::dhcp::CqlLease6Exchange, and isc::dhcp::CqlLease4Exchange.

virtual boost::any isc::dhcp::CqlLeaseExchange::retrieve ( )

overridepure virtual

Copy received data into the derived class' object.

Copies information about the entity to be retrieved into a holistic object. Called in executeSelect(). Not implemented for base class CqlExchange. To be implemented in derived classes.
