Detailed Description

template<typename MYSELF, typename ARRAY, BASESORTFLAGS FLAGS = BASESORTFLAGS::NONE, Bool PARALLEL = false>
class maxon::SortedArray< MYSELF, ARRAY, FLAGS, PARALLEL >

Sorted array. The class can be combined with any standard array type. Sorting is done on first read access, e.g. if you access the array by using the index operator. Note that sorted arrays will be extremely slow if read and write access is constantly alternating, as for every write access a sort needs to be done, which needs O(log n) time. In those cases other datastructures will be better suited. Please also take into consideration that sorted arrays are not thread-safe, even for read-access unless you call Sort() once before multiple threads start reading the data (if the array was in a non-sorted state the first read-access will sort it otherwise, which will obviously cause problems)

If the data type to be sorted is unknown to DefaultCompare you should inherit from SortedArray and define a LessThan() and an IsEqual() method for comparison of elements. For example:

class MySortedArray : public SortedArray<MySortedArray, BaseArray<MyType>>
{
public:
  static Bool LessThan(const MyType& a, const MyType& b) { return a < b; }
  static Bool IsEqual(const MyType& a, const MyType& b) { return a == b; }
};
MySortedArray a;
a.Append(x) iferr_return;
a.Append(y) iferr_return;

Note: Note that the classes that will be sorted have special requirements regarding copy and move constructors .; Note that the comparison must fulfill the condition (a < b) == !(b < a). If this is not the case the sort algorithm will crash. To avoid mistakes when comparing tuples use LexicographicalCompare.

Template Parameters

MYSELF	The class itself.
ARRAY	The used array, e.g. BaseArray, BlockArray or PointerArray.
FLAGS	See BASESORTFLAGS, normally can be left at default.
PARALLEL	Use parallel sorting, for details see parallelsort.h.

Note: Note that the array element class has special requirements regarding copy and move constructors .

Returns: Number of array elements.

◆ GetCapacityCount()

Returns: Number of array elements for which memory has been allocated.

◆ operator[]()

const TYPE& operator[] ( Int idx ) const

Array (subscript) operator for const objects.

Parameters

[in] idx Element index (if it's out of bounds you will get an error in debug code only, otherwise it will crash).

◆ InsertPtr()

ResultPtr<TYPE> InsertPtr	(	Int	position,
		TYPE *	x
	)

PointerArray specific: Inserts a pointer to a new element at index position.

Parameters

[in]	position	Insert index (the array size will increase and the existing elements are moved).
[in]	x	Pointer to new element (SortedArray will take ownership of it).

Returns: Element pointer or OutOfMemoryError if the allocation failed (or position is out of boundaries).

		ARGS &&...	args
	)

Inserts new elements at index position (all elements from position on are moved by the the count of values).

Parameters

[in]	position	Insert index (the array size will increase and the existing elements are moved).
[in]	args	Block with values to be copied/moved. If the block points to nullptr, only its count is used, and you have to call the constructor of the new elements manually.

[in,out]	dst	Used to return pointer to the erased element (must not be null).

Returns: Pointer to the element that is now at position. If position equals the that of the element after Erase(), a valid pointer is returned but you are not allowed to access it. A nullptr is only returned on failure (position was out of bounds).

◆ SwapErase() [1/2]

ResultMem SwapErase	(	Int	position,
		Int	eraseCnt = `1`

	)

Determines a contiguous block of array elements which contains the element at index. For a BaseArray, this yields the whole array as a block.

Parameters

[out]	block	Block which contains the element at `index`.

Returns: Start index of the block. The requested element can be found within the block at index - start index.

◆ GetBlock() [2/2]

Int GetBlock	(	Int	position,

Erases (removes and deletes) elements.

Parameters

[in]	position	Erase position.
[in]	eraseCnt	Number of elements to be erased (if eraseCnt is higher than what is available at position Erase() will succeed, but remove only the number of available elements).

Returns: Iterator for the element that is now at position (its operator Bool() will return false if something failed).

◆ Resize()

ResultMem Resize	(	Int	newCnt,
		COLLECTION_RESIZE_FLAGS	resizeFlags = `COLLECTION_RESIZE_FLAGS::DEFAULT`
	)

Parameters

[in]	newCnt	New array size.
[in]	resizeFlags	See COLLECTION_RESIZE_FLAGS (support depends on the inherited array).

Returns: False if allocation failed.

◆ Pop()

Parameters

[out] dst Nullptr or pointer to return value.

Returns: True if there was at least one element.

◆ GetIndex()

Int GetIndex ( const TYPE & x ) const

Gets the index of the element. The element must be part of the array, otherwise (e.g. if x is a copy of an array element) InvalidArrayIndex will be returned.

Returns: Index of element or InvalidArrayIndex (not element of this).

◆ CopyFrom() [1/2]

Result<void> CopyFrom ( const SortedArray< MYSELF, ARRAY, FLAGS, PARALLEL > & src )

Copies an array.

Parameters

[in] src Source array.

Returns: OK on success.

[in]	resizeFlags	If ON_GROW_FIT_TO_SIZE is set, the collection will use only as much memory as needed to hold the data.

◆ SortChanged()

void SortChanged ( )

Marks the array as non-sorted. Sorting will happen upon the next read access.

◆ Sort()

void Sort ( )

Manually sorts the array.

◆ FindValue() [1/2]

TYPE* FindValue ( const SEARCH & key )

Finds an element in an array. The time for searching will be O(log(n)).

Parameters

[in] key The key that the array is searched for.

Returns: If an element is found a pointer to it will be returned, otherwise the result is nullptr. If multiple elements have the same key value the first of those elements will be returned.

◆ FindValue() [2/2]

const TYPE* FindValue ( const SEARCH & key ) const

Finds an element in an array. The time for searching will be O(log(n)).

Parameters

[in] key The key that the array is searched for.

Returns: If an element is found a pointer to it will be returned, otherwise the result is nullptr. If multiple elements have the same key value the first of those elements will be returned.

◆ FindIndex()

Int FindIndex ( const SEARCH & key ) const

Finds the index of an element in an array. The time for searching will be O(log(n)).

Parameters

[in] key The key that the array is searched for.

Returns: If an element is found its index will be returned, otherwise the result is the bitwise inverse of the index where key would be inserted (which is always negative). If multiple elements have the same key value the index of the first of those elements will be returned.

◆ InsertValue() [1/2]

ResultRef<TYPE> InsertValue ( const SEARCH & key )

Finds an element in an array or insert it if it was not found. The time for this operation will be O(log(n)) for searching plus O(n) for inserting. Keep in mind that the resulting pointer will only be valid right after the operation as any additional array operation might shuffle array indices. To use this routine the SortedArray class must define the following member:

static void InitInsertData(T& initme, const SEARCH& key);

key

PyObject * key

Definition: abstract.h:289

Parameters

[in] key The key that the array is searched for.

Returns: Element reference or OutOfMemoryError if the allocation failed.

◆ InsertValue() [2/2]

ResultRef<TYPE> InsertValue	(	const SEARCH &	key,
		Bool &	newElement,
		Int *	index = `nullptr`
	)

Finds an element in an array or insert it if it was not found. The time for this operation will be O(log(n)) for searching plus O(n) for inserting. Keep in mind that the resulting pointer will only be valid right after the operation as any additional array operation might shuffle array indices. The value should be filled right after the function returns. InitInsertData is not being called.

Parameters

[in]	key	The key that the array is searched for.
[out]	newElement	Specifies if the element was newly inserted (true) or if it was found in the array (false)
