Detailed Description

template<typename ElementType, typename TypeOfCriticalSectionToUse = DummyCriticalSection, int minimumAllocatedSize = 0>
class juce::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.

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

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

inline

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.

◆ fill()

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

const ElementType& juce::Array< ElementType, TypeOfCriticalSectionToUse, minimumAllocatedSize >::getReference ( int index ) const

inlinenoexcept

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. Obviously this can be dangerous, so only use it when absolutely necessary.

Parameters

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

See also: operator[], getFirst, getLast

◆ getReference() [2/2]

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

ElementType& juce::Array< ElementType, TypeOfCriticalSectionToUse, minimumAllocatedSize >::getReference ( int index )

inlinenoexcept

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.

Parameters

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

See also: operator[], getFirst, getLast

◆ getUnchecked()

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

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

inline

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)

◆ indexOf()

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

int juce::Array< ElementType, TypeOfCriticalSectionToUse, minimumAllocatedSize >::indexOf ( ParameterType elementToLookFor ) const

inline

Finds the index of the first element which matches the value passed in.

This will search the array for the given object, and return the index of its first occurrence. If the object isn't found, the method will return -1.

Parameters

elementToLookFor the value or object to look for

Returns: the index of the object, or -1 if it's not found

Referenced by juce::SelectedItemSet< SelectableItemType >::deselect().

◆ indexOfSorted()

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

template<typename ElementComparator , typename TargetValueType >

int juce::Array< ElementType, TypeOfCriticalSectionToUse, minimumAllocatedSize >::indexOfSorted	(	ElementComparator &	comparator,
		TargetValueType	elementToLookFor
	)		const

inline

Finds the index of an element in the array, assuming that the array is sorted.

This will use a comparator to do a binary-chop to find the index of the given element, if it exists. 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
elementToLookFor	the element to search for

Returns: the index of the element, or -1 if it's not found

◆ insert()

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

void juce::Array< ElementType, TypeOfCriticalSectionToUse, minimumAllocatedSize >::insert	(	int	indexToInsertAt,
		ParameterType	newElement
	)

inline

Inserts a new element into the array at a given position.

If the index is less than 0 or greater than the size of the array, the element will be added to the end of the array. Otherwise, it will be inserted into the array, moving all the later elements along to make room.

Parameters

indexToInsertAt	the index at which the new element should be inserted (pass in -1 to add it to the end)
newElement	the new object to add to the array

◆ insertArray()

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

void juce::Array< ElementType, TypeOfCriticalSectionToUse, minimumAllocatedSize >::insertArray	(	int	indexToInsertAt,
		const ElementType *	newElements,
		int	numberOfElements
	)

inline

Inserts an array of values into this array at a given position.

If the index is less than 0 or greater than the size of the array, the new elements will be added to the end of the array. Otherwise, they will be inserted into the array, moving all the later elements along to make room.

Parameters

indexToInsertAt	the index at which the first new element should be inserted
newElements	the new values to add to the array
numberOfElements	how many items are in the array

See also: insert, add, addSorted, set

◆ insertMultiple()

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

void juce::Array< ElementType, TypeOfCriticalSectionToUse, minimumAllocatedSize >::insertMultiple	(	int	indexToInsertAt,
		ParameterType	newElement,
		int	numberOfTimesToInsertIt
	)

inline

Inserts multiple copies of an element into the array at a given position.

If the index is less than 0 or greater than the size of the array, the element will be added to the end of the array. Otherwise, it will be inserted into the array, moving all the later elements along to make room.

Parameters

indexToInsertAt	the index at which the new element should be inserted
newElement	the new object to add to the array
numberOfTimesToInsertIt	how many copies of the value to insert

◆ minimiseStorageOverheads()

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

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

inline

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.

◆ move()

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

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

inlinenoexcept

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

◆ operator!=()

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

template<class OtherArrayType >

bool juce::Array< ElementType, TypeOfCriticalSectionToUse, minimumAllocatedSize >::operator!= ( const OtherArrayType & other ) const

inline

Compares this array to another one.

Two arrays are considered equal if they both contain the same set of elements, in the same order.

Parameters

other the other array to compare with

◆ operator=() [1/2]

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

template<class OtherArrayType >

bool juce::Array< ElementType, TypeOfCriticalSectionToUse, minimumAllocatedSize >::operator== ( const OtherArrayType & other ) const

inline

Compares this array to another one.

Two arrays are considered equal if they both contain the same set of elements, in the same order.

Parameters

other the other array to compare with

◆ operator[]()

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

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

inline

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)

◆ remove() [1/2]

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

void juce::Array< ElementType, TypeOfCriticalSectionToUse, minimumAllocatedSize >::remove ( const ElementType * elementToRemove )

inline

Removes an element from the array.

This will remove the element pointed to by the given iterator, and move back all the subsequent elements to close the gap. If the iterator passed in does not point to an element within the array, behaviour is undefined.

Parameters

◆ removeRange()

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

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

inline

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.

◆ resize()

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

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

inline

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.

void juce::Array< ElementType, TypeOfCriticalSectionToUse, minimumAllocatedSize >::set	(	int	indexToChange,
		ParameterType	newValue
	)

inline

Replaces an element with a new value.

If the index is less than zero, this method does nothing. If the index is beyond the end of the array, the item is added to the end of the array.

Parameters

indexToChange	the index whose value you want to change
newValue	the new value to set for this index.

		ParameterType	newValue
	)

inline

Replaces an element with a new value without doing any bounds-checking.

This just sets a value directly in the array's internal storage, so you'd better make sure it's in range!

Parameters

indexToChange	the index whose value you want to change
newValue	the new value to set for this index.

◆ sort() [1/2]

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

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

inline

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.

Referenced by juce::Array< juce::MPEInstrument::Listener * >::sort().

◆ sort() [2/2]

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

template<class ElementComparator >

void juce::Array< ElementType, TypeOfCriticalSectionToUse, minimumAllocatedSize >::sort	(	ElementComparator &	comparator,
		bool	retainOrderOfEquivalentItems = `false`
	)

inline

Sorts the elements in the array.

This will use a comparator object to sort the elements into order. The object passed must have a method of the form:

int compareElements (ElementType first, ElementType second);

..and this method must return:

a value of < 0 if the first comes before the second
a value of 0 if the two objects are equivalent
a value of > 0 if the second comes before the first

To improve performance, the compareElements() method can be declared as static or const.

Parameters

comparator	the comparator to use for comparing elements.
retainOrderOfEquivalentItems	if this is true, then items which the comparator says are equivalent will be kept in the order in which they currently appear in the array. This is slower to perform, but may be important in some cases. If it's false, a faster algorithm is used, but equivalent elements may be rearranged.

◆ swap()

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

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

inline

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

◆ swapWith()

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

template<class OtherArrayType >

void juce::Array< ElementType, TypeOfCriticalSectionToUse, minimumAllocatedSize >::swapWith ( OtherArrayType & otherArray )

inlinenoexcept

This swaps the contents of this array with those of another array.

If you need to exchange two arrays, this is vastly quicker than using copy-by-value because it just swaps their internal pointers.
