Detailed Description

Constant class for string constants.

Contains an irep_idt representing the constant string.

Member Typedef Documentation

◆ kindt

using constant_string2t::kindt = constant_string_kindt

Constructor & Destructor Documentation

◆ constant_string2t() [1/2]

constant_string2t::constant_string2t	(	const type2tc &	type,
		const irep_idt &	stringref,
		constant_string_kindt	kind )

inline

Primary constructor.

Parameters

type	Type of this string; presumably an array_type2t.
stringref	String pool'd string we're dealing with
kind	The kind of string literal: DEFAULT: "" WIDE : L"" UNICODE: u8"", u"" and U""

◆ constant_string2t() [2/2]

constant_string2t::constant_string2t ( const constant_string2t & ref )

default

Member Function Documentation

◆ array_size()

size_t constant_string2t::array_size ( ) const

sizeof(literal)/sizeof(*literal), i.e., the number of elements in the underlying array, including the '\0' terminator

◆ at()

expr2tc constant_string2t::at ( size_t i ) const

Extract the i-th element from the string for i between 0 and to_array_type(this->type).array_size (not the same as value.c_str()[i] when to_array_type(this->type).subtype != char type).

◆ to_array()

expr2tc constant_string2t::to_array ( ) const

Convert string to a constant length array of characters.
