Tools.h++ Class Reference

Adds c to the collection and returns it. If an item is already in the collection which isEqual
to c, then the old item is returned and the new item is not inserted.
virtual RWClassID
isA() const;
Redefined from class RWCollectable to return __RWSET.
virtual RWBoolean
isEmpty() const;
Inherited from class RWCollectable.
virtual RWBoolean
isEqual(const RWCollectable* a) const;
Redefined from class RWCollection.
void
intersectWith(const RWSet& h, RWSet& ret) const;
Computes the intersection of self and h, and inserts the result into ret (which may be either
empty or not, depending on the effect desired). It may be slightly more efficient than
operator*=().
virtual size_t
occurrencesOf(const RWCollectable* target) const;
Redefined from class RWCollection. Returns the count of entries that isEqual to the item
pointed to by target. Because duplicates are not allowed for this collection, only 0 or 1 can
be returned.
virtual RWCollectable*
remove(const RWCollectable* target);
Redefined from class RWCollection. Returns and removes the item that isEqual to the item
pointed to by target, or nil if there is no item.
virtual void
removeAndDestroy(const RWCollectable* target);
Inherited from class RWCollection.
void
resize(size_t n = 0);
Resizes the internal hashing table to leave n slots. If n==0, resizes to 3*entries()/2.
virtual void
restoreGuts(RWvistream&);
virtual void
restoreGuts(RWFile&);
virtual void
saveGuts(RWvostream&) const;
