Classes
struct	infix_opt
class	format_expr_configt

Functions
static bool	bracket_subexpression (const exprt &sub_expr, const exprt &expr)
	We use the precendences that most readers expect (i.e., the ones you learn in primary school), and stay clear of the surprising ones that C has.
static std::ostream &	format_rec (std::ostream &os, const multi_ary_exprt &src)
	This formats a multi-ary expression, adding parentheses where indicated by bracket_subexpression.
static std::ostream &	format_rec (std::ostream &os, const binary_exprt &src)
	This formats a binary expression, which we do as for multi-ary expressions.
static std::ostream &	format_rec (std::ostream &os, const unary_exprt &src)
	This formats a unary expression, adding parentheses very aggressively.
static std::ostream &	format_rec (std::ostream &os, const constant_exprt &src)
	This formats a constant.
std::ostream &	fallback_format_rec (std::ostream &os, const exprt &expr)
std::ostream &	format_rec (std::ostream &os, const exprt &expr)
	Formats an expression in a generic syntax that is inspired by C/C++/Java, and is meant for debugging.

Variables

Function Documentation

bracket_subexpression()

static bool bracket_subexpression ( const exprt &  sub_expr, const exprt &  expr  )

static

We use the precendences that most readers expect (i.e., the ones you learn in primary school), and stay clear of the surprising ones that C has.

fallback_format_rec()

std::ostream & fallback_format_rec	(	std::ostream &	os,
		const exprt &	expr
	)

Definition at line 211 of file format_expr.cpp.

format_rec() [1/5]

static std::ostream & format_rec ( std::ostream &  os, const binary_exprt &  src  )

static

This formats a binary expression, which we do as for multi-ary expressions.

Definition at line 133 of file format_expr.cpp.

format_rec() [2/5]

static std::ostream & format_rec ( std::ostream &  os, const constant_exprt &  src  )

static

This formats a constant.

format_rec() [3/5]

std::ostream & format_rec	(	std::ostream &	os,
		const exprt &	expr
	)

Formats an expression in a generic syntax that is inspired by C/C++/Java, and is meant for debugging.

Definition at line 509 of file format_expr.cpp.

format_rec() [4/5]

static std::ostream & format_rec ( std::ostream &  os, const multi_ary_exprt &  src  )

static

This formats a multi-ary expression, adding parentheses where indicated by bracket_subexpression.

Definition at line 93 of file format_expr.cpp.

format_rec() [5/5]

static std::ostream & format_rec ( std::ostream &  os, const unary_exprt &  src  )
