## 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.

Appends a new element at the end of the array as long as the array doesn't already contain it.

If the array already contains an element that matches the one passed in, nothing will be done.

Parameters

  newElement | the new object to add to the array

Returns

template<class ElementComparator >

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

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

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

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

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.

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

Definition at line 382 of file juce_Array.h.

## ◆ indexOfSorted()

template<typename ElementComparator , typename TargetValueType >

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

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

| 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

|  | 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.

|  | 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

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.

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

template<class ElementComparator >

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

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 | ) |
| inline noexcept

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.
