Member Function Documentation

virtual void spot::tgba_reachable_iterator::add_state ( const state s)
pure virtual
virtual void spot::tgba_reachable_iterator::end ( )
virtual

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

virtual const state* spot::tgba_reachable_iterator::next_state ( )
pure virtual

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

Implemented in spot::tgba_reachable_iterator_breadth_first, and spot::tgba_reachable_iterator_depth_first.

virtual void spot::tgba_reachable_iterator::process_link ( const state in_s,
int  in,
const state out_s,
int  out,
const tgba_succ_iterator si 
)
virtual

Called by run() to process a transition.

Parameters
in_sThe source state
inThe source state number.
out_sThe destination state
outThe destination state number.
siThe spot::tgba_succ_iterator positionned on the current transition.

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

virtual void spot::tgba_reachable_iterator::process_state ( const state s,
int  n,
tgba_succ_iterator si 
)
virtual

Called by run() to process a state.

Parameters
sThe current state.
nA unique number assigned to s.
siThe spot::tgba_succ_iterator for s.
void spot::tgba_reachable_iterator::run ( )

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

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

virtual void spot::tgba_reachable_iterator::start ( )
virtual

Called by run() before starting its iteration.

virtual bool spot::tgba_reachable_iterator::want_state ( const state s) const
virtual

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