Detailed Description

The class RWIdentityDictionary is implemented as a hash table, for the storage and retrieval of key-value pairs. Class RWIdentityDictionary is similar to class RWHashDictionary except that items are found by requiring that they be identical (i.e., have the same address) as the key, rather than being equal (i.e., test true for isEqual()).

Both keys and values must inherit from the abstract base class RWCollectable.

The iterator for this class is RWHashDictionaryIterator.

Constructor & Destructor Documentation

◆ RWIdentityDictionary() [1/4]

RWIdentityDictionary::RWIdentityDictionary ( )

Constructs an empty identity dictionary with RWCollection::DEFAULT_CAPACITY hashing buckets.

◆ RWIdentityDictionary() [2/4]

RWIdentityDictionary::RWIdentityDictionary ( size_t n)

Constructs an empty identity dictionary with n hashing buckets.

◆ RWIdentityDictionary() [3/4]

RWIdentityDictionary::RWIdentityDictionary ( const RWIdentityDictionary & h)

Copy constructor. Makes a shallow copy of h.

◆ RWIdentityDictionary() [4/4]

RWIdentityDictionary::RWIdentityDictionary ( RWIdentityDictionary && h)
inline

Move constructor. The constructed RWIdentityDictionary takes ownership of the data owned by h.

Condition:
This method is available only on platforms with rvalue reference support.

Member Function Documentation

◆ copy()

virtual RWCollectable * RWIdentityDictionary::copy ( ) const
virtual

Returns a new, copy-constructed object of the same type as self. The caller is responsible for deleting the object.

Reimplemented from RWHashDictionary.

◆ isA()

virtual RWClassID RWIdentityDictionary::isA ( ) const
virtual

Returns __RWIDENTITYDICTIONARY.

Reimplemented from RWHashDictionary.

◆ isEqual()

virtual bool RWIdentityDictionary::isEqual ( const RWCollectable * t) const
virtual

Behaves as if compareTo(t) was invoked, returning true if the result equals 0, false otherwise.

Reimplemented from RWHashDictionary.

◆ newSpecies()

virtual RWCollectable * RWIdentityDictionary::newSpecies ( ) const
virtual

Returns a new, default-constructed object of the same type as self. The caller is responsible for deleting the object.

Reimplemented from RWHashDictionary.

◆ operator<=()

bool RWIdentityDictionary::operator<= ( const RWIdentityDictionary & h) const
inline

Returns true if self is a subset of h, that is, every element of self has a counterpart in h which isEqual().

◆ operator=() [1/2]

RWIdentityDictionary & RWIdentityDictionary::operator= ( const RWIdentityDictionary & h)

Assignment operator. Makes a shallow copy of the collection h.

◆ operator=() [2/2]

RWIdentityDictionary & RWIdentityDictionary::operator= ( RWIdentityDictionary && h)
inline

Move assignment. Self takes ownership of the data owned by h.

Condition:
This method is available only on platforms with rvalue reference support.
