void isc::flex_id::parseAndStoreExpression	(	bool	v6,
		const std::string &	expr )

Parses expression provided as text.

Parameters

memfile backend versions	Indicates if the expression refers to IPv6 or IPv4 case.
expr	Expression in the textual form.

void isc::flex_id::retrieveFlexId	(	CalloutHandle &	callout_handle,
		const Expression &	expression,
		PacketType &	pkt,
		std::vector< uint8_t > &	id )

Retrieves flexible identifier from the context or computes it.

Parameters

	callout_handle	Callout handle.
	expression	Expression to be applied for evaluation against the packet.
	pkt	Packet against which expression should be evaluated.
[out]	id	Reference to the storage into which the flexible identifier should be stored after evaluation.

storeConfiguration()

void isc::flex_id::storeConfiguration	(	bool	v6,

		const bool	apply_to_leases,
		const bool	ignore_iaid )

Stores expression.

Parameters

memfile backend versions	Indicates if the expression refers to IPv6 or IPv4 case.
expr	Expression in textual form.
apply_to_leases	Indicates if flexible identifier should be used to replace client supplied client identifier or DUID.
ignore_iaid	Indicates if IAID should be ignored.

Variable Documentation

flex_id_logger

isc::log::Logger isc::flex_id::flex_id_logger

(

"flex-id-hooks"

)

Flexible Identifier Logger.

Define the logger used to log messages. We could define it in multiple modules, but defining in a single module and linking to it saves time and space.
