Detailed Description

Functions to support the faster expression parser used by CHP/dataflow bodies.

Function Documentation

act_free_a_fexpr()

void act_free_a_fexpr

(

void *

)

External parser for fast expression parsing: free returned data

act_init_fexpr()

void act_init_fexpr

(

LFILE *

)

External parser for fast expression parsing: initialization function

act_is_a_fexpr()

int act_is_a_fexpr

(

LFILE *

)

External parser for fast expression parsing: return 1 if next symbol could be the start of an expression

act_parse_a_fexpr()

void * act_parse_a_fexpr

(

LFILE *

)

External parser for fast expression parsing: parse an expression, returning NULL on error, or data structure otherwise (returns an Expr *)

act_walk_X_fexpr()

void * act_walk_X_fexpr	(	ActTree *	,
		void *
	)

External parser for fast expression parsing: walk the parser data structure, returning the walked fexpr type (which is also an Expr ). This just calls the act_walk_X_expr() function, since it returns the same data structure as a standard expression.

Variable Documentation

expr_parse_basecase_extra

Expr *(* expr_parse_basecase_extra) (LFILE *l) ( LFILE *  l )
