Detailed Description

Arc class.

Holds a single arc in a graph/FSM. With each graph, there is an implicitly associated GmmSet and an explicitly associated SymbolTable (see Graph::get_word_sym_table()). An arc holds a destination state; an optional GMM index (corresponding to a GMM in the GmmSet); an optional word index (corresponding to a word in the SymbolTable); and a log prob (base e). Source state information is not present; if you have the arc ID (see Graph::get_first_arc_id(), Graph::get_arc()), you can look this up using Graph::get_src_state().

)

[inline]

Ctor; initializes fields to default values.

Arc::Arc	(	unsigned	dst,

		int	wordIdx,
		double	logProb
	)			[inline]

Ctor; explicitly initializes all fields.

Member Function Documentation

void Arc::assign	(	unsigned	dst,
		int	gmmIdx,
		int	wordIdx,
		double	logProb
	)			[inline]

Sets all values in arc.

The argument dst should be the destination state; gmmIdx should be the index of the associated GMM (or -1 if not present); wordIdx should be the index of the associated word (or -1 if not present); and logProb should be the log prob base e of the arc.

unsigned Arc::get_dst_state

(

)

const [inline]

Returns dest state index.

To find src state, see Graph::get_src_state().

int Arc::get_gmm

(

)

const [inline]

Returns assoc GMM index, or -1 if not present.

unsigned Arc::get_word

(

)

const [inline]

Returns assoc word index, or 0 if not present/epsilon.

To find the corresponding word spelling, see Graph::get_word_sym_table().

double Arc::get_log_prob

(

)

const [inline]

Returns assoc log prob base e.
