ASTNode

typedef struct ASTNode ASTNode

Component of the abstract syntax tree built during parsing.

Function Documentation

add_position_info()

void add_position_info	(	ASTNode *	dest,
		position	p
	)

Add position information to an ASTNode.

Parameters

dest	Destination ASTNode pointer
p	Position information

ast_debug_level_order()

void ast_debug_level_order	(	ASTNode *	root,
		LogLevel	log_level
	)

Print out an AST's level order traversal.

Parameters

root	Root of AST
log_level	Log level to print at

create_ast_identifier_leaf()

ASTNode * create_ast_identifier_leaf	(	TokenType	ttype,
		char *	symbol_name
	)

Constructs a new AST Leaf Node with the provided values for a token that is an identifier.

Parameters

ttype	TokenType of the new AST Node
symbol_name	The identifier for the provided Token information

Returns

ASTNode* The pointer to a new AST Leaf Node with the provided values

create_ast_node()

ASTNode * create_ast_node	(	TokenType	ttype,
		ASTNode *	left,
		ASTNode *	mid,

		Type	type,
		char *	symbol_name
	)

Constructs a new AST Node with the provided values.

Parameters

ttype	TokenType of the new AST Node
left	Left child subtree of the new AST Node
mid	Middle child subtree of the new AST Node
right	Right child subtree of the new AST Node
type	Type of the new AST Node
symbol_name	The identifier for the provided Token information

Returns

ASTNode* The pointer to a new AST Node with the provided values

create_ast_nonidentifier_leaf()

ASTNode * create_ast_nonidentifier_leaf	(	TokenType	ttype,
		Type	type
	)

Constructs a new AST Leaf Node with the provided values for a token that is not an identifier.

Parameters

ttype	TokenType of the new AST Node
type	Type of the new AST Node

Returns

ASTNode* The pointer to a new AST Leaf Node with the provided values

create_unary_ast_node()

ASTNode * create_unary_ast_node	(	TokenType	ttype,
		ASTNode *	child,
		Type	type,
		char *	symbol_name
	)

Constructs a new AST Unary Parent Node with the provided values.

Parameters

ttype	TokenType of the new AST Node
child	The AST Node's single child
type	Type of the new AST Node
symbol_name	The identifier for the provided Token information

Returns

ASTNode* The pointer to a new AST Unary Parent Node with the provided values
