RWHashDictionary a;
Description A RWHashDictionary represents a group of unordered values, accessible by
external keys. Duplicate keys are not allowed. Class RWHashDictionary is
implemented as a hash table of associations of keys and values. Both the key
and the value must inherit from abstract the base class RWCollectable , with
a suitable definition of the virtual function hash() and isEqual() for the
key.
This class corresponds to the Smalltalk class Dictionary .
Public constructors RWHashDictionary(size_t n = RWDEFAULT_CAPACITY);
Construct an empty hashed dictionary using n hashing buckets.
RWHashDictionary(const RWHashDictionary& hd);
Copy constructor. A shallow copy of the collection hd is made.
