void dfa_state_init

(

DFA_INFO *

dinfo

)

Initialize and allocate DFA state information list in the grammar.

Parameters:

dinfo

[i/o] DFA grammar

void dfa_state_expand	(	DFA_INFO *	dinfo,
		int	needed
	)

Expand the state information list to the required length.

Parameters:

	dinfo	[i/o] DFA grammar
	needed	[in] required new length

boolean rddfa	(	FILE *	fp,
		DFA_INFO *	dinfo
	)

Top loop function to read DFA grammar via file pointer.

Parameters:

	fp	[in] file pointer that points to the DFA grammar data
	dinfo	[out] the read data will be stored in this DFA grammar structure

Returns:

TRUE on success, FALSE on failure.

boolean rddfa_fd	(	int	fd,
		DFA_INFO *	dinfo

Top loop function to read DFA grammar via file descriptor.

Parameters:

	fd	[in] file descriptor that points to the DFA grammar data
	dinfo	[out] the read data will be stored in this DFA grammar structure

Returns:

TRUE on success, FALSE on failure.

boolean rddfa_sd	(	int	sd,
		DFA_INFO *	dinfo
	)

Top loop function to read DFA grammar via socket descriptor.

Parameters:

	sd	[in] socket descriptor that points to the DFA grammar data
	dinfo	[out] the read data will be stored in this DFA grammar structure

Returns:

TRUE on success, FALSE on failure.

boolean rddfa_line	(	char *	line,
		DFA_INFO *	dinfo,
		int *	state_max,
		int *	arc_num,
		int *	terminal_max
	)

Parse the input line and set grammar information, one by line.

Parameters:

	line	[in] text buffer that holds a line of DFA file
	dinfo	[i/o] the read data will be appended to this DFA data
	state_max	[i/o] maximum number of state id appeared, will be updated
	arc_num	[i/o] number of read arcs, will be updated
	terminal_max	[i/o] maximum number of state id appended, will be updated

Returns:

TRUE if the line was successfully parsed, FALSE if failed.

void dfa_append	(	DFA_INFO *	dst,
		DFA_INFO *	src,
		int	soffset,
		int	coffset
	)

Append the DFA state information to other.

Parameters:

	dst	[i/o] DFA grammar
	src	[i/o] DFA grammar to be appended to dst
	soffset	[in] offset state number in dst where the new state should be stored
	coffset	[in] category id offset in dst where the new data should be stored
