Detailed Description

An implementation of spot::twa_reachable_iterator that browses states breadth first.

Member Function Documentation

add_state()

virtual void spot::twa_reachable_iterator_breadth_first::add_state ( const state *  s )

overridevirtual

Called by run() to obtain the next state to process.

Implements spot::twa_reachable_iterator.

end()

virtual void spot::twa_reachable_iterator::end ( )

virtualinherited

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

next_state()

virtual const state * spot::twa_reachable_iterator_breadth_first::next_state ( )

overridevirtual

Called by run() to obtain the next state to process.

Implements spot::twa_reachable_iterator.

process_link()

virtual void spot::twa_reachable_iterator::process_link ( const state *  in_s, int  in, const state *  out_s, int  out, const twa_succ_iterator *  si  )

virtualinherited

Called by run() to process a transition.

Parameters

in_s	The source state
in	The source state number.
out_s	The destination state
out	The destination state number.
si	The spot::twa_succ_iterator positioned on the current transition.

The in_s and out_s states are owned by the spot::twa_reachable_iterator instance and destroyed when the instance is destroyed.

process_state()

virtual void spot::twa_reachable_iterator::process_state ( const state *  s, int  n, twa_succ_iterator *  si  )

virtualinherited

Called by run() to process a state.

Parameters

s	The current state.
n	A unique number assigned to s.
si	The spot::twa_succ_iterator for s.

run()

virtual void spot::twa_reachable_iterator::run ( )

virtualinherited

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

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

start()

virtual void spot::twa_reachable_iterator::start ( )

virtualinherited

Called by run() before starting its iteration.

want_state()

virtual bool spot::twa_reachable_iterator::want_state ( const state *  s ) const

virtualinherited

Called by add_state or next_states implementations to filter states. Default implementation always return true.
