Member Function Documentation

std::ostream& spot::free_list::dump_free_list ( std::ostream &  os) const
inherited

Dump the list to os for debugging.

virtual int spot::bdd_dict::anon_free_list::extend ( int  n)
virtual

Allocate n integer.

This function is called by register_n() when the free list is empty or if n consecutive integers could not be found. It should allocate more integers, possibly changing the list, and return the first integer on a range of n consecutive integer requested by the user.

Implements spot::free_list.

int spot::free_list::free_count ( ) const
inherited

Return the number of free integers on the list.

void spot::free_list::insert ( int  base,
int  n 
)
inherited

Extend the list by inserting a new pos-lenght pair.

int spot::free_list::register_n ( int  n)
inherited

Find n consecutive integers.

Browse the list of free integers until n consecutive integers are found. Extend the list (using extend()) otherwise.

Returns
the first integer of the range
void spot::free_list::release_n ( int  base,
int  n 
)
inherited

Release n consecutive integers starting at base.

void spot::free_list::remove ( int  base,
int  n = 0 
)
inherited

Remove n consecutive entries from the list, starting at base.

void spot::free_list::remove ( free_list_type::iterator  i,
int  base,
int  n 
)
protectedinherited

Remove n consecutive entries from the list, starting at base.
