Detailed Description

The type of an expression, extends irept.

Types may have subtypes. This is modeled with two subs named “subtype” (a single type) and “subtypes” (a vector of types). The class typet only adds specialized methods for accessing the subtype information to the interface of irept. For pre-defined types see std_types.h and mathematical_types.h.

◆ check()

static void typet::check	(	const typet &	,
		const	validation_modet = `validation_modet::INVARIANT`
	)

inlinestatic

Check that the type is well-formed (shallow checks only, i.e., subtypes are not checked)

Subclasses may override this function to provide specific well-formedness checks for the corresponding types.

The validation mode indicates whether well-formedness check failures are reported via DATA_INVARIANT violations or exceptions.

◆ validate()

static void typet::validate	(	const typet &	type,

		const validation_modet	vm = `validation_modet::INVARIANT`
	)

inlinestatic

Check that the type is well-formed, assuming that its subtypes have already been checked for well-formedness.

Subclasses may override this function to provide specific well-formedness checks for the corresponding types.

The validation mode indicates whether well-formedness check failures are reported via DATA_INVARIANT violations or exceptions.

◆ validate_full()

static void typet::validate_full	(	const typet &	type,
		const namespacet &	ns,
		const validation_modet	vm = `validation_modet::INVARIANT`
	)

inlinestatic

Check that the type is well-formed (full check, including checks of subtypes)

Subclasses may override this function, though in most cases the provided implementation should be sufficient.

The validation mode indicates whether well-formedness check failures are reported via DATA_INVARIANT violations or exceptions.
