## Detailed Description

template<class ObjectClass, class TypeOfCriticalSectionToUse = DummyCriticalSection>
class juce::ReferenceCountedArray< ObjectClass, TypeOfCriticalSectionToUse >

Holds a list of objects derived from ReferenceCountedObject, or which implement basic reference-count handling methods.

The template parameter specifies the class of the object you want to point to - the easiest way to make a class reference-countable is to simply make it inherit from ReferenceCountedObject or SingleThreadedReferenceCountedObject, but if you need to, you can roll your own reference-countable class by implementing a set of methods called incReferenceCount(), decReferenceCount(), and decReferenceCountWithoutDeleting(). See ReferenceCountedObject for examples of how these methods should behave.

A ReferenceCountedArray holds objects derived from ReferenceCountedObject, and takes care of incrementing and decrementing their ref counts when they are added and removed from the array.

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

## ◆ addIfNotAlreadyThere() [1/2]

template<class ObjectClass , class TypeOfCriticalSectionToUse = DummyCriticalSection>

bool juce::ReferenceCountedArray< ObjectClass, TypeOfCriticalSectionToUse >::addIfNotAlreadyThere | ( | const ObjectClassPtr & | newObject | ) |
| inline

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

If the array already contains a matching object, nothing will be done.

Parameters

  newObject | the new object to add to the array

Returns
  true if the object has been added, false otherwise

## ◆ addOrReplaceSorted()

template<class ObjectClass , class TypeOfCriticalSectionToUse = DummyCriticalSection>
template<class ElementComparator >

void juce::ReferenceCountedArray< ObjectClass, TypeOfCriticalSectionToUse >::addOrReplaceSorted | ( | ElementComparator & | comparator,
|  | ObjectClass * | newObject )
| inline noexcept

Inserts or replaces an object in the array, assuming it is sorted.

This is similar to addSorted, but if a matching element already exists, then it will be replaced by the new one, rather than the new one being added as well.

Definition at line 542 of file juce_ReferenceCountedArray.h.

## ◆ addSorted()

template<class ObjectClass , class TypeOfCriticalSectionToUse = DummyCriticalSection>
template<class ElementComparator >

|  | ObjectClass * | newObject )
| inline noexcept

Inserts a new object into the array assuming that the array is sorted.

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

Parameters

  comparator | the comparator object to use to compare the elements - see the sort() method for details about this object's form
  newObject | the new object to insert to the array

Returns
  the index at which the new object was added

## ◆ ensureStorageAllocated()

template<class ObjectClass , class TypeOfCriticalSectionToUse = DummyCriticalSection>

void juce::ReferenceCountedArray< ObjectClass, TypeOfCriticalSectionToUse >::ensureStorageAllocated | ( | const 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.

Definition at line 828 of file juce_ReferenceCountedArray.h.

## ◆ getObjectPointer()

template<class ObjectClass , class TypeOfCriticalSectionToUse = DummyCriticalSection>

ObjectClass * juce::ReferenceCountedArray< ObjectClass, TypeOfCriticalSectionToUse >::getObjectPointer | ( | int | index | ) | const
| inline noexcept

Returns a raw pointer to the object at this index in the array.

If the index is out-of-range, this will return a null pointer, (and it could be null anyway, because it's ok for the array to hold null pointers as well as objects).

## ◆ getRawDataPointer()

template<class ObjectClass , class TypeOfCriticalSectionToUse = DummyCriticalSection>

ObjectClass ** juce::ReferenceCountedArray< ObjectClass, TypeOfCriticalSectionToUse >::getRawDataPointer | ( |  | ) | const
| inline noexcept

Returns a pointer to the actual array data. This pointer will only be valid until the next time a non-const method is called on the array.

Definition at line 234 of file juce_ReferenceCountedArray.h.

## ◆ getUnchecked()

template<class ObjectClass , class TypeOfCriticalSectionToUse = DummyCriticalSection>

ObjectClassPtr juce::ReferenceCountedArray< ObjectClass, TypeOfCriticalSectionToUse >::getUnchecked | ( | int | index | ) | const
| inline noexcept

Returns a pointer to the object at this index in the array, without checking whether the index is in-range.

This is a faster and less safe version of operator[] which doesn't check the index passed in, so it can be used when you're sure the index is always going to be legal.

Definition at line 180 of file juce_ReferenceCountedArray.h.

## ◆ indexOf() [1/2]

template<class ObjectClass , class TypeOfCriticalSectionToUse = DummyCriticalSection>

int juce::ReferenceCountedArray< ObjectClass, TypeOfCriticalSectionToUse >::indexOf | ( | const ObjectClass * | objectToLookFor | ) | const
| inline noexcept

Finds the index of the first occurrence of an object in the array.

Parameters

  objectToLookFor | the object to look for

Returns
  the index at which the object was found, or -1 if it's not found

Finds the index of the first occurrence of an object in the array.

Parameters

  objectToLookFor | the object to look for

Returns
  the index at which the object was found, or -1 if it's not found

template<class ElementComparator >

int juce::ReferenceCountedArray< ObjectClass, TypeOfCriticalSectionToUse >::indexOfSorted | ( | ElementComparator & | comparator,
|  | const ObjectClass * | objectToLookFor ) const
| noexcept

Finds the index of an object 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
  objectToLookFor | the object to search for

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

## ◆ insert() [1/2]

template<class ObjectClass , class TypeOfCriticalSectionToUse = DummyCriticalSection>

ObjectClass * juce::ReferenceCountedArray< ObjectClass, TypeOfCriticalSectionToUse >::insert | ( | int | indexToInsertAt,
|  | const ObjectClassPtr & | newObject )
| inline

Inserts a new object into the array at the given index.

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.

This will increase the new object's reference count.

Parameters

  indexToInsertAt | the index at which the new element should be inserted
  newObject | the new object to add to the array

| inline

Inserts a new object into the array at the given index.

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.

This will increase the new object's reference count.

## ◆ minimiseStorageOverheads()

template<class ObjectClass , class TypeOfCriticalSectionToUse = DummyCriticalSection>

void juce::ReferenceCountedArray< ObjectClass, TypeOfCriticalSectionToUse >::minimiseStorageOverheads | ( |  | ) |
| inline noexcept

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.

template<class ObjectClass , class TypeOfCriticalSectionToUse = DummyCriticalSection>

void juce::ReferenceCountedArray< ObjectClass, TypeOfCriticalSectionToUse >::move | ( | int | currentIndex,
|  | int | newIndex )
| inline noexcept

Moves one of the objects to a different position.

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

## ◆ operator[]()

template<class ObjectClass , class TypeOfCriticalSectionToUse = DummyCriticalSection>

ObjectClassPtr juce::ReferenceCountedArray< ObjectClass, TypeOfCriticalSectionToUse >::operator[] | ( | int | index | ) | const
| inline noexcept

Returns a pointer to the object at this index in the array.

If the index is out-of-range, this will return a null pointer, (and it could be null anyway, because it's ok for the array to hold null pointers as well as objects).

## ◆ remove()

template<class ObjectClass , class TypeOfCriticalSectionToUse = DummyCriticalSection>

void juce::ReferenceCountedArray< ObjectClass, TypeOfCriticalSectionToUse >::remove | ( | int | indexToRemove | ) |
| inline

Removes an object from the array.

This will remove the object at a given index and move back all the subsequent objects to close the gap.

If the index passed in is out-of-range, nothing will happen.

The object that is removed will have its reference count decreased, and may be deleted if not referenced from elsewhere.

Parameters

  indexToRemove | the index of the element to remove

template<class ObjectClass , class TypeOfCriticalSectionToUse = DummyCriticalSection>

ObjectClassPtr juce::ReferenceCountedArray< ObjectClass, TypeOfCriticalSectionToUse >::removeAndReturn | ( | int | indexToRemove | ) |
| inline

Removes and returns an object from the array.

This will remove the object at a given index and return it, moving back all the subsequent objects to close the gap. If the index passed in is out-of-range, nothing will happen and a null pointer will be returned.

Parameters

  indexToRemove | the index of the element to remove

void juce::ReferenceCountedArray< ObjectClass, TypeOfCriticalSectionToUse >::removeLast | ( | int | howManyToRemove = 1 | ) |
| inline

Removes the last n objects from the array.

The objects that are removed will have their reference counts decreased, and may be deleted if not referenced from elsewhere.

Parameters

  howManyToRemove | how many objects to remove from the end of the array

## ◆ removeObject() [1/2]

template<class ObjectClass , class TypeOfCriticalSectionToUse = DummyCriticalSection>

void juce::ReferenceCountedArray< ObjectClass, TypeOfCriticalSectionToUse >::removeObject | ( | const ObjectClassPtr & | objectToRemove | ) |
| inline

Removes the first occurrence of a specified object from the array.

If the item isn't found, no action is taken. If it is found, it is removed and has its reference count decreased.

Parameters

  objectToRemove | the object to try to remove

template<class ObjectClass , class TypeOfCriticalSectionToUse = DummyCriticalSection>

void juce::ReferenceCountedArray< ObjectClass, TypeOfCriticalSectionToUse >::removeObject | ( | ObjectClass * | objectToRemove | ) |
| inline

Removes the first occurrence of a specified object from the array.

If the item isn't found, no action is taken. If it is found, it is removed and has its reference count decreased.

Parameters

  objectToRemove | the object to try to remove

## ◆ removeRange()

template<class ObjectClass , class TypeOfCriticalSectionToUse = DummyCriticalSection>

void juce::ReferenceCountedArray< ObjectClass, TypeOfCriticalSectionToUse >::removeRange | ( | int | startIndex,
|  | int | numberToRemove )
| inline

Removes a range of objects from the array.

This will remove a set of objects, starting from the given index, and move any 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.

The objects that are removed will have their reference counts decreased, and may be deleted if not referenced from elsewhere.

Parameters

  startIndex | the index of the first object to remove
  numberToRemove | how many objects should be removed

## ◆ set() [1/2]

template<class ObjectClass , class TypeOfCriticalSectionToUse = DummyCriticalSection>

void juce::ReferenceCountedArray< ObjectClass, TypeOfCriticalSectionToUse >::set | ( | int | indexToChange,
|  | const ObjectClassPtr & | newObject )
| inline

Replaces an object in the array with a different one.

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

The object being added has its reference count increased, and if it's replacing another object, then that one has its reference count decreased, and may be deleted.

Parameters

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

| inline

Replaces an object in the array with a different one.

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

The object being added has its reference count increased, and if it's replacing another object, then that one has its reference count decreased, and may be deleted.

Parameters

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

## ◆ sort()

template<class ObjectClass , class TypeOfCriticalSectionToUse >
template<class ElementComparator >

void juce::ReferenceCountedArray< ObjectClass, TypeOfCriticalSectionToUse >::sort | ( | ElementComparator & | comparator,
|  | bool | retainOrderOfEquivalentItems = false )
| noexcept

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<class ObjectClass , class TypeOfCriticalSectionToUse = DummyCriticalSection>

void juce::ReferenceCountedArray< ObjectClass, TypeOfCriticalSectionToUse >::swap | ( | int | index1,
|  | int | index2 )
| inline noexcept

Swaps a pair of objects in the array.

If either of the indexes passed in is out-of-range, nothing will happen, otherwise the two objects at these positions will be exchanged.

Definition at line 711 of file juce_ReferenceCountedArray.h.

## ◆ swapWith()

template<class ObjectClass , class TypeOfCriticalSectionToUse = DummyCriticalSection>
template<class OtherArrayType >

void juce::ReferenceCountedArray< ObjectClass, TypeOfCriticalSectionToUse >::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.
