sort_operands()

bool sort_operands

(

sort operands of an expression according to ordering defined by operator<

parameters: operand list

Returns

modifies operand list returns true iff nothing was changed

try_get_string_data_array()

std::optional< std::reference_wrapper< const array_exprt > > try_get_string_data_array	(	const exprt &	content,
		const namespacet &	ns
	)

Get char sequence from content field of a refined string expression.

If content is of the form &id[e], where id is an array-typed symbol expression (and e is any expression), return the value of the symbol id (as given by the value field of the symbol in the namespace ns); otherwise return an empty optional.

Parameters

content	content field of a refined string expression
ns	namespace

Returns

array expression representing the char sequence which forms the content of the refined string expression, empty optional if the content cannot be determined
