Inheritance diagram for HybridSet< T, SMALL, LARGE, THRESHOLD, REVERSE_THRESHOLD >:

Detailed Description

template<typename T, typename SMALL, typename LARGE, Int THRESHOLD, Int REVERSE_THRESHOLD>
class maxon::HybridSet< T, SMALL, LARGE, THRESHOLD, REVERSE_THRESHOLD >

A HybridSet is an implementation of a set using an underlying HybridMap.

See HashSet for more examples on how to use sets in general.

Template Parameters
TType of elements of the set.
SMALLA map selector template to choose the map implementation to use for a small number of entries.
LARGEA map selector template to choose the map implementation to use for a large number of entries.
THRESHOLDWhen the number of entries reaches THRESHOLD, HybridMap switches to the LARGE implementation.
REVERSE_THRESHOLDWhen the number of entries falls below REVERSE_THRESHOLD, HybridMap switches back to the SMALL implementation. If this is negative, this will never happen.

◆ Contains()

Bool Contains ( typename ByValueParam< T >::type  value) const

Checks if this set contains value.

Parameters
[in]valueThe value to check.
Returns

◆ Insert() [1/3]

void Insert ( ) const

◆ Insert() [2/3]

ResultMemT<Iterator> Insert ( const T &  value,
Bool added = BoolLValue() 
)

Adds value to this set. If value is already contained in this set, nothing happens, and added is set to false.

Parameters
[in]valueValue to add to this set.
[out]addedThis will be set to true if the element didn't exist before in the set and it could be added successfully, otherwise it will be set to false.
Returns
Iterator to the entry for the given key or OutOfMemoryError if the allocation failed.

◆ Insert() [3/3]

ResultMemT<Iterator> Insert ( T &&  value,
Bool added = BoolLValue() 
)

Adds value to this set. If value is already contained in this set, nothing happens, and added is set to false.

Parameters
[in]valueValue to add to this set. When a new element has to be added, value will be moved into the new element.
[out]addedThis will be set to true if the element didn't exist before in the set and it could be added successfully, otherwise it will be set to false.
Returns
Iterator to the entry for the given key or OutOfMemoryError if the allocation failed.

◆ InsertKey() [1/2]

ResultRef<const T> InsertKey ( const T &  value,
Bool added = BoolLValue() 
)

Adds value to this set. If value is already contained in this set, nothing happens, and added is set to false.

Parameters
[in]valueValue to add to this set.
[out]addedThis will be set to true if the element didn't exist before in the set and it could be added successfully, otherwise it will be set to false.
Returns
Pointer to the value in the set, or nullptr if the element had to be added, but the allocation failed.

◆ InsertKey() [2/2]

ResultRef<const T> InsertKey ( T &&  value,
Bool added = BoolLValue() 
)

Adds value to this set. If value is already contained in this set, nothing happens, and added is set to false.

Parameters
[in]valueValue to add to this set. When a new element has to be added, value will be moved into the new element.
[out]addedThis will be set to true if the element didn't exist before in the set and it could be added successfully, otherwise it will be set to false.
Returns
Pointer to the value in the set, or nullptr if the element had to be added, but the allocation failed.

◆ Erase() [1/2]

Result<Bool> Erase ( const T &  value)

Remove value from this set. If value isn't contained in this set, nothing happens.

Parameters
[in]valueValue to remove from this set.
Returns
True if an entry was found and removed for value, otherwise false or an error if a memory allocation failed.

◆ Begin() [1/2]

ConstIterator Begin ( ) const

◆ End() [1/2]

ConstIterator End ( ) const

◆ Begin() [2/2]

Iterator Begin ( )

◆ End() [2/2]

Iterator End ( )

◆ Erase() [2/2]

Iterator Erase ( const Iterator it)

◆ Find() [1/2]

Iterator Find ( typename KEY  = K)

Finds the entry for the given key in this map.

Parameters
[in]keyKey to search for.
Returns
Iterator pointing to the entry with the given key, or an invalid iterator if this doesn't exist.

◆ Find() [2/2]

ConstIterator Find ( typename KEY  = K)

Finds the entry for the given key in this map.

Parameters
[in]keyKey to search for.
Returns
Iterator pointing to the entry with the given key, or an invalid iterator if this doesn't exist.

◆ GetCount()

Int GetCount

Returns the number of entries in this map.

Returns
Number of entries.

◆ GetOperationCountForSearch()

Int GetOperationCountForSearch

Returns an estimate of the number of operations needed to locate a given key in this map. This is used when two collections are compared: The iteration goes over the collection which would require more operations for search, and each entry is searched in the other collection.

Returns
Estimate for the number of operations.

◆ SetCapacityHint()

ResultMem SetCapacityHint

Increases the internal capacity of the map so that it is prepared to hold at least the given number of elements. This is forwarded to the currently used underlying map implementation.

Parameters
[in]capacityThe desired capacity.
[in]resizeFlagsIf ON_GROW_FIT_TO_SIZE is set, the collection will use only as much memory as needed to hold the data.
Returns
False if allocation failed.

◆ Reset()

void Reset

Resets the map. This destructs all entries and frees any memory held by the map. The map will also switch to the SMALL implementation if necessary, so it will be in a state as if it had been newly constructed.

◆ Flush()

void Flush

Flushes the map so that it is empty afterwards. Depending on the underlying implementations, memory may still be held for re-use. If REVERSE_THRESHOLD is non-negative, Flush() will also switch back to the SMALL implementation.

◆ GetMemorySize()

Int GetMemorySize

Returns the memory usage of this map.

Returns
Memory size in bytes.
