virtual void spot::evtgba_reachable_iterator_depth_first::add_state ( const state s) [virtual]
virtual void spot::evtgba_reachable_iterator::end ( ) [virtual, inherited]

Called by run() once all states have been explored.

Called by run() to obtain the.

Implements spot::evtgba_reachable_iterator.

virtual void spot::evtgba_reachable_iterator::process_link ( int  in,
int  out,
const evtgba_iterator si 
) [virtual, inherited]

Called by run() to process a transition.

Parameters:
inThe source state number.
outThe destination state number.
siThe spot::evtgba_iterator positionned on the current transition.
virtual void spot::evtgba_reachable_iterator::process_state ( const state s,
int  n,
evtgba_iterator si 
) [virtual, inherited]

Called by run() to process a state.

Parameters:
sThe current state.
nAn unique number assigned to s.
siThe spot::evtgba_iterator for s.

Iterate over all reachable states of a spot::evtgba.

This is a template method that will call add_state(), next_state(), start(), end(), process_state(), and process_link(), while it iterate over state.

virtual void spot::evtgba_reachable_iterator::start ( int  n) [virtual, inherited]

Called by run() before starting its iteration.

Parameters:
nThe number of initial states.
