Detailed Description

template<typename TYPE, typename HASH = hash<TYPE>, typename ALLOC = allocator<couple<const TYPE, const bool>>>
class original::hashSet< TYPE, HASH, ALLOC >

Hash table based implementation of the set interface.

Template Parameters

TYPE	Element type (must be hashable)
HASH	Hash function type (default: hash<TYPE>)
ALLOC	Allocator type (default: allocator<couple<const TYPE, const bool>>)

This class provides a concrete implementation of the set interface using a hash table with separate chaining. It combines the functionality of:

set (interface)
hashTable (storage with bool values)
iterable (iteration support)

Performance Characteristics:

Insertion: Average O(1), Worst O(n)
Lookup: Average O(1), Worst O(n)
Deletion: Average O(1), Worst O(n)

The implementation guarantees:

Unique elements (no duplicates)
Type safety
Exception safety (basic guarantee)
Iterator validity unless modified

Constructor & Destructor Documentation

◆ hashSet() [1/3]

template<typename TYPE , typename HASH , typename ALLOC >

original::hashSet< TYPE, HASH, ALLOC >::hashSet	(	HASH	hash = `HASH{}`,
		ALLOC	alloc = `ALLOC{}`
	)

explicit

Constructs empty hashSet.

Parameters

hash	Hash function to use
alloc	Allocator to use

◆ hashSet() [2/3]

template<typename TYPE , typename HASH , typename ALLOC >

original::hashSet< TYPE, HASH, ALLOC >::hashSet ( const hashSet< TYPE, HASH, ALLOC > & other )

Copy constructor.

Parameters

other hashSet to copy

Performs deep copy of all elements and buckets

Note: Allocator is copied if propagate_on_container_copy_assignment is true

◆ hashSet() [3/3]

template<typename TYPE , typename HASH , typename ALLOC >

original::hashSet< TYPE, HASH, ALLOC >::hashSet ( hashSet< TYPE, HASH, ALLOC > && other )

noexcept

Move constructor.

Parameters

other hashSet to move from

Transfers ownership of resources from other

Note: Leaves other in valid but unspecified state

Member Function Documentation

◆ add()

template<typename TYPE , typename HASH , typename ALLOC >

bool original::hashSet< TYPE, HASH, ALLOC >::add ( const TYPE & e )

override

Adds new element.

Parameters

e	Element to add

Returns: true if added, false if element existed

◆ begins()

template<typename TYPE , typename HASH , typename ALLOC >

original::hashSet< TYPE, HASH, ALLOC >::Iterator * original::hashSet< TYPE, HASH, ALLOC >::begins ( ) const

overridevirtual

Gets begin iterator.

Returns: New iterator at first element

Implements original::iterable< const TYPE >.

◆ className()

template<typename TYPE , typename HASH , typename ALLOC >

std::string original::hashSet< TYPE, HASH, ALLOC >::className ( ) const

overridevirtual

Gets class name.

Returns: "hashSet"

Reimplemented from original::printable.

◆ contains()

template<typename TYPE , typename HASH , typename ALLOC >

bool original::hashSet< TYPE, HASH, ALLOC >::contains ( const TYPE & e ) const

override

Checks if element exists.

Parameters

e	Element to check

Returns: true if element exists

◆ ends()

template<typename TYPE , typename HASH , typename ALLOC >

original::hashSet< TYPE, HASH, ALLOC >::Iterator * original::hashSet< TYPE, HASH, ALLOC >::ends ( ) const

overridevirtual

Gets end iterator.

Returns: New iterator at position past last element

Implements original::iterable< const TYPE >.

◆ operator=() [1/2]

template<typename TYPE , typename HASH , typename ALLOC >

original::hashSet< TYPE, HASH, ALLOC > & original::hashSet< TYPE, HASH, ALLOC >::operator= ( const hashSet< TYPE, HASH, ALLOC > & other )

Copy assignment operator.

Parameters

other hashSet to copy

Returns: Reference to this hashSet

Performs deep copy of all elements and buckets

Note: Allocator is copied if propagate_on_container_copy_assignment is true

◆ operator=() [2/2]

template<typename TYPE , typename HASH , typename ALLOC >

original::hashSet< TYPE, HASH, ALLOC > & original::hashSet< TYPE, HASH, ALLOC >::operator= ( hashSet< TYPE, HASH, ALLOC > && other )

noexcept

Move assignment operator.

Parameters

other hashSet to move from

Returns: Reference to this hashSet

Transfers ownership of resources from other

Note: Leaves other in valid but unspecified state; Allocator is moved if propagate_on_container_move_assignment is true

◆ remove()

template<typename TYPE , typename HASH , typename ALLOC >

bool original::hashSet< TYPE, HASH, ALLOC >::remove ( const TYPE & e )

override

Removes element.

Parameters

e	Element to remove

Returns: true if removed, false if element didn't exist

◆ size()

template<typename TYPE , typename HASH , typename ALLOC >

original::u_integer original::hashSet< TYPE, HASH, ALLOC >::size ( ) const

override

Gets number of elements.

Returns: Current size

◆ swap()

template<typename TYPE , typename HASH , typename ALLOC >

void original::hashSet< TYPE, HASH, ALLOC >::swap ( hashSet< TYPE, HASH, ALLOC > & other )

noexcept

Swaps contents with another hashSet.

Parameters

other hashSet to swap with

Note: No-throw guarantee if element swap and allocator swap are noexcept

Efficiently exchanges:

Bucket arrays and their contents
Size counters
Hash function instances
Allocators (if propagate_on_container_swap is true)

Performance: O(1) - pointer swaps only Iterator Invalidation: All iterators from both sets are invalidated

Example usage:

hashSet<int> set1, set2;
set1.add(1); set2.add(2);
set1.swap(set2);
// Now set1 contains 2, set2 contains 1

◆ toString()

template<typename TYPE , typename HASH , typename ALLOC >

std::string original::hashSet< TYPE, HASH, ALLOC >::toString ( bool enter ) const

overridevirtual

Converts to string representation.

Parameters

enter Add newline if true

Returns: String representation

Reimplemented from original::printable.
