Detailed Description

template<typename ElementType, typename TypeOfCriticalSectionToUse = DummyCriticalSection, int minimumAllocatedSize = 0>
class Array< ElementType, TypeOfCriticalSectionToUse, minimumAllocatedSize >

Holds a resizable array of primitive or copy-by-value objects.

Examples of arrays are: Array<int>, Array<Rectangle> or Array<MyClass*>

The Array class can be used to hold simple, non-polymorphic objects as well as primitive types - to do so, the class must fulfill these requirements:

it must have a copy constructor and assignment operator
it must be able to be relocated in memory by a memcpy without this causing any problems - so objects whose functionality relies on external pointers or references to themselves can not be used.

You can of course have an array of pointers to any kind of object, e.g. Array<MyClass*>, but if you do this, the array doesn't take any ownership of the objects - see the OwnedArray class or the ReferenceCountedArray class for more powerful ways of holding lists of objects.

For holding lists of strings, you can use Array<String>, but it's usually better to use the specialised class StringArray, which provides more useful functions.

To make all the array's methods thread-safe, pass in "CriticalSection" as the templated TypeOfCriticalSectionToUse parameter, instead of the default DummyCriticalSection.

◆ operator[]()

template<typename ElementType , typename TypeOfCriticalSectionToUse = DummyCriticalSection, int minimumAllocatedSize = 0>

ElementType Array< ElementType, TypeOfCriticalSectionToUse, minimumAllocatedSize >::operator[] ( int index ) const

Returns one of the elements in the array.

If the index passed in is beyond the range of valid elements, this will return a default value.

If you're certain that the index will always be a valid element, you can call getUnchecked() instead, which is faster.

Parameters

index the index of the element being requested (0 is the first element in the array)

See also: getUnchecked, getFirst, getLast

References Array< ElementType, TypeOfCriticalSectionToUse, minimumAllocatedSize >::getLock().

◆ getUnchecked()

template<typename ElementType , typename TypeOfCriticalSectionToUse = DummyCriticalSection, int minimumAllocatedSize = 0>

ElementType Array< ElementType, TypeOfCriticalSectionToUse, minimumAllocatedSize >::getUnchecked ( int index ) const

Returns one of the elements in the array, without checking the index passed in.

Unlike the operator[] method, this will try to return an element without checking that the index is within the bounds of the array, so should only be used when you're confident that it will always be a valid index.

Parameters

index the index of the element being requested (0 is the first element in the array)

noexcept

Returns a direct reference to one of the elements in the array, without checking the index passed in.

This is like getUnchecked, but returns a direct reference to the element, so that you can alter it directly. Obviously this can be dangerous, so only use it when absolutely necessary.

◆ resize()

template<typename ElementType , typename TypeOfCriticalSectionToUse = DummyCriticalSection, int minimumAllocatedSize = 0>

void Array< ElementType, TypeOfCriticalSectionToUse, minimumAllocatedSize >::resize ( int targetNumItems )

This will enlarge or shrink the array to the given number of elements, by adding or removing items from its end.

If the array is smaller than the given target size, empty elements will be appended until its size is as specified. If its size is larger than the target, items will be removed from its end to shorten it.

template<class ElementComparator >

int Array< ElementType, TypeOfCriticalSectionToUse, minimumAllocatedSize >::addSorted	(	ElementComparator &	comparator,
		ParameterType	newElement )

Inserts a new element into the array, assuming that the array is sorted.

This will use a comparator to find the position at which the new element should go. If the array isn't sorted, the behaviour of this method will be unpredictable.

Parameters

comparator	the comparator to use to compare the elements - see the sort() method for details about the form this object should take
newElement	the new element to insert to the array

Returns: the index at which the new item was added

◆ addUsingDefaultSort()

template<typename ElementType , typename TypeOfCriticalSectionToUse = DummyCriticalSection, int minimumAllocatedSize = 0>

void Array< ElementType, TypeOfCriticalSectionToUse, minimumAllocatedSize >::addUsingDefaultSort ( ParameterType newElement )

Inserts a new element into the array, assuming that the array is sorted.

This will use the DefaultElementComparator class for sorting, so your ElementType must be suitable for use with that class. If the array isn't sorted, the behaviour of this method will be unpredictable.

Parameters

newElement the new element to insert to the array

void Array< ElementType, TypeOfCriticalSectionToUse, minimumAllocatedSize >::removeRange	(	int	startIndex,
		int	numberToRemove )

Removes a range of elements from the array.

This will remove a set of elements, starting from the given index, and move subsequent elements down to close the gap.

If the range extends beyond the bounds of the array, it will be safely clipped to the size of the array.

Parameters

◆ swap()

template<typename ElementType , typename TypeOfCriticalSectionToUse = DummyCriticalSection, int minimumAllocatedSize = 0>

void Array< ElementType, TypeOfCriticalSectionToUse, minimumAllocatedSize >::swap	(	int	index1,
		int	index2 )

Swaps over two elements in the array.

This swaps over the elements found at the two indexes passed in. If either index is out-of-range, this method will do nothing.

Parameters

index1	index of one of the elements to swap
index2	index of the other element to swap

References Array< ElementType, TypeOfCriticalSectionToUse, minimumAllocatedSize >::getLock().

◆ move()

template<typename ElementType , typename TypeOfCriticalSectionToUse = DummyCriticalSection, int minimumAllocatedSize = 0>

void Array< ElementType, TypeOfCriticalSectionToUse, minimumAllocatedSize >::move	(	int	currentIndex,
		int	newIndex )

noexcept

Moves one of the values to a different position.

This will move the value to a specified index, shuffling along any intervening elements as required.

So for example, if you have the array { 0, 1, 2, 3, 4, 5 } then calling move (2, 4) would result in { 0, 1, 3, 4, 2, 5 }.

Parameters

currentIndex	the index of the value to be moved. If this isn't a valid index, then nothing will be done
newIndex	the index at which you'd like this value to end up. If this is less than zero, the value will be moved to the end of the array

◆ minimiseStorageOverheads()

template<typename ElementType , typename TypeOfCriticalSectionToUse = DummyCriticalSection, int minimumAllocatedSize = 0>

void Array< ElementType, TypeOfCriticalSectionToUse, minimumAllocatedSize >::minimiseStorageOverheads ( )

Reduces the amount of storage being used by the array.

Arrays typically allocate slightly more storage than they need, and after removing elements, they may have quite a lot of unused space allocated. This method will reduce the amount of allocated storage to a minimum.

References Array< ElementType, TypeOfCriticalSectionToUse, minimumAllocatedSize >::getLock().

◆ ensureStorageAllocated()

template<typename ElementType , typename TypeOfCriticalSectionToUse = DummyCriticalSection, int minimumAllocatedSize = 0>

void Array< ElementType, TypeOfCriticalSectionToUse, minimumAllocatedSize >::ensureStorageAllocated ( int minNumElements )

Increases the array's internal storage to hold a minimum number of elements.

Calling this before adding a large known number of elements means that the array won't have to keep dynamically resizing itself as the elements are added, and it'll therefore be more efficient.

References Array< ElementType, TypeOfCriticalSectionToUse, minimumAllocatedSize >::getLock().

◆ sort()

template<typename ElementType , typename TypeOfCriticalSectionToUse = DummyCriticalSection, int minimumAllocatedSize = 0>

void Array< ElementType, TypeOfCriticalSectionToUse, minimumAllocatedSize >::sort ( )

Sorts the array using a default comparison operation.

If the type of your elements isn't supported by the DefaultElementComparator class then you may need to use the other version of sort, which takes a custom comparator.

◆ getLock()

template<typename ElementType , typename TypeOfCriticalSectionToUse = DummyCriticalSection, int minimumAllocatedSize = 0>

const TypeOfCriticalSectionToUse & Array< ElementType, TypeOfCriticalSectionToUse, minimumAllocatedSize >::getLock ( ) const

noexcept

Returns the CriticalSection that locks this array.

To lock, you can call getLock().enter() and getLock().exit(), or preferably use an object of ScopedLockType as an RAII lock for it.
