Detailed Description

template<class Registry, bool SupportFastSizeQuery = true>
class ogdf::RegisteredSet< Registry, SupportFastSizeQuery >

Constant-time set operations.

Maintains a subset of indexed keys managed by a registry.

Provides efficient operations for testing membership, iteration, insertion, and deletion of elements, as well as clearing the set.

Template Parameters
RegistryThe class which manages the registered keys. Must provide the functions defined in class RegistryBase.
SupportFastSizeQueryWhether this set supports querying its size in constant instead of linear time (in the size).

Constructor & Destructor Documentation

◆ RegisteredSet() [1/3]

template<class Registry , bool SupportFastSizeQuery = true>
ogdf::RegisteredSet< Registry, SupportFastSizeQuery >::RegisteredSet ( const Registry &  R)
inlineexplicit

Creates an empty set associated with registry R.

Definition at line 62 of file RegisteredSet.h.

◆ RegisteredSet() [2/3]

template<class Registry , bool SupportFastSizeQuery = true>
ogdf::RegisteredSet< Registry, SupportFastSizeQuery >::RegisteredSet ( )
inlineexplicit

Creates an empty set associated with no registry.

Definition at line 65 of file RegisteredSet.h.

◆ RegisteredSet() [3/3]

template<class Registry , bool SupportFastSizeQuery = true>
template<bool OtherSupportsFastSizeQuery>
ogdf::RegisteredSet< Registry, SupportFastSizeQuery >::RegisteredSet ( const RegisteredSet< Registry, OtherSupportsFastSizeQuery > &  other)
inlineexplicit

Copy constructor.

Definition at line 161 of file RegisteredSet.h.

Member Function Documentation

◆ begin()

template<class Registry , bool SupportFastSizeQuery = true>
list_type::const_iterator ogdf::RegisteredSet< Registry, SupportFastSizeQuery >::begin ( ) const
inline

Definition at line 155 of file RegisteredSet.h.

◆ clear()

template<class Registry , bool SupportFastSizeQuery = true>
void ogdf::RegisteredSet< Registry, SupportFastSizeQuery >::clear ( )
inline

Removes all elements from this set.

After this operation, this set is empty and still associated with the same registry. The runtime of this operation is linear in the size(). Implementation Detail: If less than 10% of all elements are part of this set, they will be individually cleared. Otherwise, std::vector::assign(...) will be used to clear all values.

Definition at line 118 of file RegisteredSet.h.

◆ elements()

template<class Registry , bool SupportFastSizeQuery = true>
const list_type& ogdf::RegisteredSet< Registry, SupportFastSizeQuery >::elements ( ) const
inline

Returns a reference to the list of elements contained in this set.

Definition at line 144 of file RegisteredSet.h.

◆ end()

template<class Registry , bool SupportFastSizeQuery = true>
list_type::const_iterator ogdf::RegisteredSet< Registry, SupportFastSizeQuery >::end ( ) const
inline

Definition at line 157 of file RegisteredSet.h.

◆ init() [1/2]

template<class Registry , bool SupportFastSizeQuery = true>
void ogdf::RegisteredSet< Registry, SupportFastSizeQuery >::init ( )
inline

Reinitializes the set. Associates the set with no registry.

Definition at line 68 of file RegisteredSet.h.

◆ init() [2/2]

template<class Registry , bool SupportFastSizeQuery = true>
void ogdf::RegisteredSet< Registry, SupportFastSizeQuery >::init ( const Registry &  R)
inline

Reinitializes the set. Associates the set with registry R.

Definition at line 74 of file RegisteredSet.h.

◆ insert()

template<class Registry , bool SupportFastSizeQuery = true>
void ogdf::RegisteredSet< Registry, SupportFastSizeQuery >::insert ( element_type  v)
inline

Inserts element v into this set.

This operation has constant runtime. If the element is already contained in this set, nothing happens.

Precondition
v is an element in the associated registry.

Definition at line 86 of file RegisteredSet.h.

◆ isMember()

template<class Registry , bool SupportFastSizeQuery = true>
bool ogdf::RegisteredSet< Registry, SupportFastSizeQuery >::isMember ( element_type  v) const
inline

Returns true iff element v is contained in this set.

This operation has constant runtime.

Precondition
v is an element in the associated registry.

Definition at line 138 of file RegisteredSet.h.

◆ operator()()

template<class Registry , bool SupportFastSizeQuery = true>
bool ogdf::RegisteredSet< Registry, SupportFastSizeQuery >::operator() ( element_type  v) const
inline

Returns the same as isMember() to use an RegisteredSet instance as filter function.

Definition at line 141 of file RegisteredSet.h.

◆ operator=()

template<class Registry , bool SupportFastSizeQuery = true>
template<bool OtherSupportsFastSizeQuery>
RegisteredSet& ogdf::RegisteredSet< Registry, SupportFastSizeQuery >::operator= ( const RegisteredSet< Registry, OtherSupportsFastSizeQuery > &  other)
inline

Assignment operator.

Definition at line 167 of file RegisteredSet.h.

◆ registeredAt()

template<class Registry , bool SupportFastSizeQuery = true>
const Registry* ogdf::RegisteredSet< Registry, SupportFastSizeQuery >::registeredAt ( ) const
inline

Returns the associated registry.

Definition at line 147 of file RegisteredSet.h.

◆ remove()

template<class Registry , bool SupportFastSizeQuery = true>
bool ogdf::RegisteredSet< Registry, SupportFastSizeQuery >::remove ( element_type  v)
inline

Removes element v from this set and return true iff v was previously present.

This operation has constant runtime. If the element is not contained in this set, nothing happens and false is returned.

Precondition
v is an element in the associated registry.

Definition at line 100 of file RegisteredSet.h.

◆ size()

template<class Registry , bool SupportFastSizeQuery = true>
int ogdf::RegisteredSet< Registry, SupportFastSizeQuery >::size ( ) const
inline

Returns the number of elements in this set.

This operation has either linear or constant runtime, depending on SupportFastSizeQuery.

Definition at line 153 of file RegisteredSet.h.

◆ m_it

template<class Registry , bool SupportFastSizeQuery = true>
RegisteredArray<Registry, ListIterator<element_type>, false> ogdf::RegisteredSet< Registry, SupportFastSizeQuery >::m_it
private

m_it[v] contains the list iterator pointing to v if v is contained in this set, or an invalid list iterator otherwise.
