virtual spot::saba_reachable_iterator::~saba_reachable_iterator (  )  [virtual]

Member Function Documentation

virtual void spot::saba_reachable_iterator::add_state ( const saba_state s  )  [pure virtual]
virtual void spot::saba_reachable_iterator::end (  )  [virtual]

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

virtual const saba_state* spot::saba_reachable_iterator::next_state (  )  [pure virtual]

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

Implemented in spot::saba_reachable_iterator_depth_first, and spot::saba_reachable_iterator_breadth_first.

virtual void spot::saba_reachable_iterator::process_link ( const saba_state in_s,
int  in,
const saba_state out_s,
int  out,
const saba_state_conjunction sc,
int  sc_id,
const saba_succ_iterator si 
) [virtual]

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.
sc The spot::saba_state_conjunction positionned on the current conjunction.
sc_id An unique number for the this transition assigned to sc.
si The spot::saba_succ_iterator positionned on the current transition.

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

virtual void spot::saba_reachable_iterator::process_state ( const saba_state s,
int  n 
) [virtual]

Called by run() to process a state.

Parameters:
s The current state.
n A unique number assigned to s.
virtual void spot::saba_reachable_iterator::process_state_conjunction ( const saba_state in_s,
int  in,
const saba_state_conjunction sc,
int  sc_id,
const saba_succ_iterator si 
) [virtual]

Called by run() to process a conjunction of states.

Parameters:
in_s The current state.
in An unique number assigned to in_s.
sc The spot::saba_state_conjunction positionned on the current conjunction.
sc_id An unique number for the this transition assigned to sc.
si The spot::saba_succ_iterator positionned on the current transition.
void spot::saba_reachable_iterator::run (  ) 

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

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

virtual void spot::saba_reachable_iterator::start (  )  [virtual]

Called by run() before starting its iteration.

virtual bool spot::saba_reachable_iterator::want_state ( const saba_state s  )  const [virtual]

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