Unigine::HashSet Class

Header: #include <UnigineHashSet.h>

A hash set container template. The hash set stores keys in an unspecified order. It allows for fast lookup of the keys.

HashSet Class

Members


HashSet ( ) #

Default constructor that produces an empty hash set.

HashSet ( const HashSet& o ) #

Constructor. Creates a hash set by copying a source hash set.

Arguments

  • const HashSet& o - Hash set.

HashSet ( HashSet&& o ) #

Constructor. Creates a hash set by copying a source hash set.

Arguments

  • HashSet&& o - Hash set.

HashSet ( std::initializer_list<Key> list ) #

Constructor. Creates a hash set from given list of keys.

Arguments

  • std::initializer_list<Key> list - List of keys.

HashSet<Key, Counter> & operator= ( const HashSet& o ) #

Assignment operator for the hash set.

Arguments

  • const HashSet& o - Hash set.

HashSet<Key, Counter> & operator= ( HashSet&& o ) #

Assignment operator for the hash set.

Arguments

  • HashSet&& o - Hash set.

void append ( const Key& key ) #

Appends a key to the hash set.

Arguments

  • const Key& key - Key.

void append ( Key&& key ) #

Appends a key to the hash set.

Arguments

  • Key&& key - Key.

void append ( const HashSet& o ) #

Appends a given hash set to the current one.

Arguments

  • const HashSet& o - Hash set.

void append ( HashSet&& o ) #

Appends a given hash set to the current one.

Arguments

  • HashSet&& o - Hash set.

void remove ( const HashSet& o ) #

Removes all keys of a given hash set from the current one.

Arguments

  • const HashSet& o - Hash set.

void insert ( const Key& key ) #

Inserts a key into the hash set.

Arguments

  • const Key& key - Key.

void insert ( Key&& key ) #

Inserts a key into the hash set.

Arguments

  • Key&& key - Key.

void insert ( const HashSet& o ) #

Inserts a given hash set into the current one.

Arguments

  • const HashSet& o - Hash set.

void insert ( HashSet&& o ) #

Inserts a given hash set into the current one.

Arguments

  • HashSet&& o - Hash set.

void subtract ( const HashSet& o ) #

Removes all keys of a given hash set from the current one.

Arguments

  • const HashSet& o - Hash set.

bool operator== ( const HashSet& o ) const#

Checks if two hash sets are equal. The hash sets are considered equal if their keys are the same.

Arguments

  • const HashSet& o - Hash set.

Return value

Returns 1 if sets are equal; otherwise, 0 is returned.

bool operator!= ( const HashSet& o ) const#

Checks if two hash sets are not equal. The hash sets are considered equal if their keys are the same.

Arguments

  • const HashSet& o - Hash set.

Return value

Returns 1 if sets are not equal; otherwise, 0 is returned.

HashSet<Key, Counter> & operator+= ( const Key& key ) #

Inserts a given key into the hash set and returns the updated set.

Arguments

  • const Key& key - Key.

Return value

Updated hash set.

HashSet<Key, Counter> & operator+= ( const HashSet& o ) #

Inserts a given hash set into the current one and returns the updated set.

Arguments

  • const HashSet& o - Hash set.

Return value

Updated hash set.

HashSet<Key, Counter> & operator-= ( const Key& key ) #

Removes a given key from the current hash set and returns the updated set.

Arguments

  • const Key& key - Key.

Return value

Updated hash set.

HashSet<Key, Counter> & operator-= ( const HashSet& o ) #

Removes a given hash set from the current one and returns the updated set.

Arguments

  • const HashSet& o - Hash set.

Return value

Updated hash set.

HashSet<Key, Counter> fromKeys ( const Key* keys, size_t size ) #

Appends keys to the hash set and returns the updated set.

Arguments

  • const Key* keys - Keys pointer.
  • size_t size - Keys size.

Return value

Updated hash set.

HashSet<Key, Counter> fromKeys ( const Vector<Key>& keys ) #

Appends keys to the hash set and returns the updated set.

Arguments

  • const Vector<Key>& keys - Vector of keys.

Return value

Updated hash set.

HashSet<Key, Counter> fromKeys ( Vector<Key>& keys ) #

Appends keys to the hash set and returns the updated set.

Arguments

  • Vector<Key>& keys - Vector of keys.

Return value

Updated hash set.
