Detailed Description

The expression_char class is used to represent an abstract character-valued expression node.

Constructor & Destructor Documentation

virtual expression_char::~expression_char

(

)

[virtual]

The destructor.

expression_char::expression_char	(	const location &	locn,
		unsigned char	value
	)

The constructor.

Parameters:

	locn	the source code location of the expression.
	value	the value of the character constant

expression_char::expression_char

(

)

[private]

The default constructor. Do not use.

expression_char::expression_char

(

const expression_char &

)

[private]

The copy constructor. Do not use.

Member Function Documentation

void expression_char::logical_traversal	(	int	pprec,
		label::pointer &	true_branch,
		label::pointer &	false_branch,
		bool	fall_through_preference
	)			[protected]

int expression_char::get_precedence

(

)

const [protected, virtual]

The get_precedence method is used to obtain the precedence of this expression node.

The highest precedence has the highest absolute value, the lowest precedence gets the lowest absolute value.

Implements expression.

type::pointer expression_char::get_type

(

)

const [protected, virtual]

The get_type method is used to get the type of this expression.

Implements expression.

bool expression_char::is_lvalue

(

)

const [protected, virtual]

The is_lvalue method is used to determine whether or not this expression is suitable to appear on the left hand side of an assignment expression.

Implements expression.

side_effect_t expression_char::has_side_effect

(

)

const [protected, virtual]

The has_side_effect method is used to determine if an expression has any effect. It is used by the parse to produce "statement with no effect" warnings.

Implements expression.

bool expression_char::is_constant

(

)

const [protected, virtual]

The is_constant method may be used to determine whether this expression node is a constant, or this tree would evaluate to a constant.

The default implementation is conservative, and always returns false.

Returns:

bool; true if constant, false if not.

Reimplemented from expression.

long expression_char::get_integer_value

(

)

const [protected, virtual]

The get_integer_value method is used to obtain the integer value of an expression node. It is an error, and the results are undefined (probably rm -rf or worse), if this is not a constant integer expression node.

Reimplemented from expression.

expression_char& expression_char::operator=

(

const expression_char &

)

[private]

The assignment operator. Do not use.
