Tools.h++ Class Reference

If there exists an element t in self that compares equal to a, assigns t to k and returns true.
Otherwise, returns false and leaves the value of k unchanged.
bool
find(bool (*fn)(const_reference,void*), void* d,
value_type& k) const;
If there exists an element t in self such that the expression ((*fn)(t,d)) is true, assigns t to k
and returns true. Otherwise, returns false and leaves the value of k unchanged. fn points to
a user-defined tester function which must have prototype:
bool yourTester(const_reference a, void* d);
Client data may be passed through parameter d.
bool
insert(const_reference a);
Adds the item a to the collection. Returns true if the insertion is successful, otherwise
returns false. The function will return true unless the collection already holds an element
with the equivalent key.
void
intersection(const RWTValHashSet<T,H,EQ>& rhs);
void
intersection(const rw_hashset<T,H,EQ>& rhs);
Destructively performs a set theoretic intersection of self and rhs, replacing the contents of
self with the result.
bool
isEmpty() const;
Returns true if there are no items in the collection, false otherwise.
bool
isEquivalent(const RWTValHashSet<T,H,EQ>& s) const;
Returns true if there is set equivalence between self and s, and returns false otherwise.
bool
isProperSubsetOf(const RWTValHashSet<T,H,EQ>& s) const;
Returns true if self is a proper subset of s, and returns false otherwise.
bool
isSubsetOf(const RWTValHashSet<T,H,EQ>& s) const;
Returns true if self is a subset of s or if self is set equivalent to s, false otherwise.
size_type
occurrencesOf(const_reference a) const;
Returns the number of elements t in self that compare equal to a.
