Tools.h++ Class Reference

isEmpty() const;
Inherited from class RWBTree.
virtual RWBoolean
isEqual(const RWCollectable* a) const;
Inherited from class RWCollectable.
virtual size_t
occurrencesOf(const RWCollectable* target) const;
Redefined from class RWCollection. Returns the number of keys that compare equal with target.
Because duplicates are not allowed, this function can only return 0 or 1.
virtual RWCollectable*
remove(const RWCollectable* target);
Redefined from class RWCollection. Removes the key and value pair for which the key compares equal
to the object pointed to by target. Returns the key, or nil if no match was found.
virtual void
removeAndDestroy(const RWCollectable* target);
Redefined from class RWCollection. Removes and deletes the key and value pair for which the key
compares equal to the object pointed to by target. Note that both the key and the value are deleted.
Does nothing if the key is not found.
RWCollectable*
removeKeyAndValue(const RWCollectable* target,
RWCollectable*& v);
Removes the key and value pair for which the key compares equal to the object pointed to by target.
Returns the key, or nil if no match was found. The value is put in v. You are responsible for defining v
before calling this function.
virtual void
restoreGuts(RWvistream&);
virtual void
restoreGuts(RWFile&);
virtual void
saveGuts(RWvostream&) const;
virtual void
saveGuts(RWFile&) const;
Inherited from class RWCollection.
virtual RWCollection*
select(RWtestCollectable testfunc, void* x) const;
Evaluates the function pointed to by tst for the key of each item in the RWBTreeDictionary. It inserts
keys and values for which the function returns TRUE into a new RWBTreeDictionary allocated off the
heap and returns a pointer to this new collection. Because the new dictionary is allocated off the heap,
you are responsible for deleting it when done. This is not a virtual function.
virtual RWCollection*
select(RWtestCollectablePair testfunc, void* x) const;
Evaluates the function pointed to by tst for both the key and the value of each item in the
RWBTreeDictionary. It inserts keys and values for which the function returns TRUE into a new
