Functions
The Node Operation Functions
A function for each of the 15 different types of nodes defined by the SABNF grammar. These functions are for internal, parser use only. They are never to be called directly by the application.

Function Documentation

vAbg()

void vAbg	(	parser *	spCtx,
		const opcode *	spop
	)

Definition at line 233 of file operators-sabnf.c.

vAen()

void vAen	(	parser *	spCtx,
		const opcode *	spop
	)

Definition at line 249 of file operators-sabnf.c.

vAlt()

void vAlt	(	parser *	spCtx,
		const opcode *	spop
	)

Definition at line 66 of file operators-abnf.c.

vAnd()

void vAnd	(	parser *	spCtx,
		const opcode *	spop
	)

Definition at line 106 of file operators-sabnf.c.

vBka()

void vBka	(	parser *	spCtx,
		const opcode *	spOp
	)

The positive look-behind operator. Looks for a pattern match by iteratively working back from the current parser offset to the beginning of the input string (even if a sub-string is being parsed that does not begin and the beginning of the string) or the maximum look-behind length specified in the parser configuration.

1. BKA exists mainly to support a pattern-matching engine.
2. This is not an efficient procedure. BKA should be avoided if parsing speed is imperative.
3. Look behind stops at the first (and shortest) phrase matched.
4. If the look-behind phrase can accept an empty string BKA will always succeed.

Definition at line 189 of file operators-sabnf.c.

vBkn()

void vBkn	(	parser *	spCtx,
		const opcode *	spOp
	)

The negative look-behind operator. Looks for a pattern match by iteratively working back from the current parser offset to the beginning of the input string (even if a sub-string is being parsed that does not begin and the beginning of the string) or the maximum look-behind length specified in the parser configuration.

1. BKN exists mainly to support a pattern-matching engine.
2. This is not an efficient procedure. BKN should be avoided if parsing speed is imperative.
3. Look behind stops at the first (and shortest) phrase matched.
4. If the look-behind phrase can accept an empty string BKN will always fail.
