Detailed Description

template<class ObjectType>
class juce::ReferenceCountedObjectPtr< ObjectType >

A smart-pointer class which points to a reference-counted object.

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.

When using this class, you'll probably want to create a typedef to abbreviate the full templated name - e.g.

struct MyClass  : public ReferenceCountedObject
{
    using Ptr = ReferenceCountedObjectPtr<MyClass>;
    ...
}

using juce::ReferenceCountedObjectPtr< ObjectType >::ReferencedType = ObjectType

The class being referenced by this pointer.

Constructor & Destructor Documentation

ReferenceCountedObjectPtr() [1/7]

template<class ObjectType>

juce::ReferenceCountedObjectPtr< ObjectType >::ReferenceCountedObjectPtr ( )

default

Creates a pointer to a null object.

ReferenceCountedObjectPtr() [2/7]

template<class ObjectType>

juce::ReferenceCountedObjectPtr< ObjectType >::ReferenceCountedObjectPtr ( decltype(nullptr) )

inlinenoexcept

Creates a pointer to a null object.

ReferenceCountedObjectPtr() [3/7]

template<class ObjectType>

juce::ReferenceCountedObjectPtr< ObjectType >::ReferenceCountedObjectPtr ( ReferencedType * refCountedObject )

inlinenoexcept

Creates a pointer to an object. This will increment the object's reference-count.

ReferenceCountedObjectPtr() [4/7]

template<class ObjectType>

juce::ReferenceCountedObjectPtr< ObjectType >::ReferenceCountedObjectPtr ( ReferencedType & refCountedObject )

inlinenoexcept

Creates a pointer to an object. This will increment the object's reference-count.

ReferenceCountedObjectPtr() [5/7]

template<class ObjectType>

juce::ReferenceCountedObjectPtr< ObjectType >::ReferenceCountedObjectPtr ( const ReferenceCountedObjectPtr< ObjectType > & other )

inlinenoexcept

Copies another pointer. This will increment the object's reference-count.

ReferenceCountedObjectPtr() [6/7]

template<class ObjectType>

juce::ReferenceCountedObjectPtr< ObjectType >::ReferenceCountedObjectPtr ( ReferenceCountedObjectPtr< ObjectType > && other )

inlinenoexcept

Takes-over the object from another pointer.

ReferenceCountedObjectPtr() [7/7]

template<class ObjectType>

template<typename Convertible>

juce::ReferenceCountedObjectPtr< ObjectType >::ReferenceCountedObjectPtr ( const ReferenceCountedObjectPtr< Convertible > & other )

inlinenoexcept

Copies another pointer. This will increment the object's reference-count (if it is non-null).

~ReferenceCountedObjectPtr()

template<class ObjectType>

juce::ReferenceCountedObjectPtr< ObjectType >::~ReferenceCountedObjectPtr ( )

inline

Destructor. This will decrement the object's reference-count, which will cause the object to be deleted when the ref-count hits zero.

Member Function Documentation

decIfNotNull()

template<class ObjectType>

void juce::ReferenceCountedObjectPtr< ObjectType >::decIfNotNull ( ReferencedType * o )

inlinestaticprivatenoexcept

get()

template<class ObjectType>

ReferencedType * juce::ReferenceCountedObjectPtr< ObjectType >::get ( ) const

inlinenoexcept

Returns the object that this pointer references. The pointer returned may be null, of course.

getObject()

template<class ObjectType>

ReferencedType * juce::ReferenceCountedObjectPtr< ObjectType >::getObject ( ) const

inline

incIfNotNull()

template<class ObjectType>

void juce::ReferenceCountedObjectPtr< ObjectType >::incIfNotNull ( ReferencedType * o )

inlinestaticprivatenoexcept

operator ReferencedType *()

template<class ObjectType>

juce::ReferenceCountedObjectPtr< ObjectType >::operator ReferencedType * ( ) const

inlinenoexcept

Returns the object that this pointer references. The pointer returned may be null, of course. Note that this methods allows the compiler to be very lenient with what it allows you to do with the pointer, it's safer to disable this by setting JUCE_STRICT_REFCOUNTEDPOINTER=1, which increased type safety and can prevent some common slip-ups.

operator!=() [1/3]

template<class ObjectType>

inlinenoexcept

Compares two ReferenceCountedObjectPtrs.

operator!=() [2/3]

template<class ObjectType>

bool juce::ReferenceCountedObjectPtr< ObjectType >::operator!= ( const ReferenceCountedObjectPtr< ObjectType > & other ) const

inlinenoexcept

Compares two ReferenceCountedObjectPtrs.

operator!=() [3/3]

template<class ObjectType>

bool juce::ReferenceCountedObjectPtr< ObjectType >::operator!= ( decltype(nullptr) ) const

inlinenoexcept

Checks whether this pointer is null

operator*()

template<class ObjectType>

ReferencedType & juce::ReferenceCountedObjectPtr< ObjectType >::operator* ( ) const

operator=() [3/6]

template<class ObjectType>

ReferenceCountedObjectPtr & juce::ReferenceCountedObjectPtr< ObjectType >::operator= ( decltype(nullptr) )

inline

Resets this pointer to a null pointer.

operator=() [4/6]

template<class ObjectType>

ReferenceCountedObjectPtr & juce::ReferenceCountedObjectPtr< ObjectType >::operator= ( ReferenceCountedObjectPtr< ObjectType > && other )

inlinenoexcept

Takes-over the object from another pointer.

operator=() [5/6]

template<class ObjectType>

ReferenceCountedObjectPtr & juce::ReferenceCountedObjectPtr< ObjectType >::operator= ( ReferencedType & newObject )
