Constructor & Destructor Documentation

◆ element_address_exprt() [1/2]

element_address_exprt::element_address_exprt	(	const exprt &	base,
		exprt	index )

constructor for element addresses.

The base address must be a pointer to an element. The index is expected to have an integer type.

Definition at line 158 of file pointer_expr.cpp.

◆ element_address_exprt() [2/2]

element_address_exprt::element_address_exprt	(	exprt	base,
		exprt	index,
		pointer_typet	type )

constructor for element addresses.

The base address must be a pointer to an element. The index is expected to have an integer type.
