Detailed Description

Implements a unique set or dictionary of states.

This class provides the means to construct and access a unique set of states. This provide the ability to validate state values, look up their text labels, and their handlers.

Member Function Documentation

◆ add()

void isc::util::StateSet::add	(	const int	value,
		const std::string &	label,
		StateHandler	handler,
		const StatePausing &	state_pausing
	)

Adds a state definition to the set of states.

Parameters

value	is the numeric value of the state
label	is the text label to assign to the state
handler	is the bound instance method which handles the state's
state_pausing	state pausing mode for the given state.

Exceptions

StateModelError if the value is already defined in the set, or if the label is null or blank.
