Detailed Description

template<class ObjectType>
class OptionalScopedPointer< ObjectType >

Holds a pointer to an object which can optionally be deleted when this pointer goes out of scope.

This acts in many ways like a std::unique_ptr, but allows you to specify whether or not the object is deleted.

Constructor & Destructor Documentation

◆ OptionalScopedPointer() [1/5]

template<class ObjectType>

OptionalScopedPointer< ObjectType >::OptionalScopedPointer ( )

default

Creates an empty OptionalScopedPointer.

◆ OptionalScopedPointer() [2/5]

template<class ObjectType>

OptionalScopedPointer< ObjectType >::OptionalScopedPointer	(	ObjectType *	objectToHold,
		bool	takeOwnership
	)

Creates an OptionalScopedPointer to point to a given object, and specifying whether the OptionalScopedPointer will delete it.

If takeOwnership is true, then the OptionalScopedPointer will act like a std::unique_ptr, deleting the object when it is itself deleted. If this parameter is false, then the OptionalScopedPointer just holds a normal pointer to the object, and won't delete it.

◆ OptionalScopedPointer() [3/5]

template<class ObjectType>

OptionalScopedPointer< ObjectType >::OptionalScopedPointer ( OptionalScopedPointer< ObjectType > && other )

noexcept

Takes ownership of the object that another OptionalScopedPointer holds.

Like a normal std::unique_ptr, the objectToTransferFrom object will become null, as ownership of the managed object is transferred to this object.

The flag to indicate whether or not to delete the managed object is also copied from the source object.

◆ OptionalScopedPointer() [4/5]

template<class ObjectType>

OptionalScopedPointer< ObjectType >::OptionalScopedPointer ( std::unique_ptr< ObjectType > && ptr )

explicitnoexcept

Takes ownership of the object owned by ptr.

◆ OptionalScopedPointer() [5/5]

template<class ObjectType>

OptionalScopedPointer< ObjectType >::OptionalScopedPointer ( ObjectType & ref )

explicitnoexcept

Points to the same object as ref, but does not take ownership.

◆ ~OptionalScopedPointer()

template<class ObjectType>

OptionalScopedPointer< ObjectType >::~OptionalScopedPointer ( )

noexcept

The destructor may or may not delete the object that is being held, depending on the takeOwnership flag that was specified when the object was first passed into an OptionalScopedPointer constructor.

Member Function Documentation

◆ operator=()

template<class ObjectType>

OptionalScopedPointer& OptionalScopedPointer< ObjectType >::operator= ( OptionalScopedPointer< ObjectType > && other )

noexcept

Takes ownership of the object that another OptionalScopedPointer holds.

Like a normal std::unique_ptr, the objectToTransferFrom object will become null, as ownership of the managed object is transferred to this object.

The ownership flag that says whether or not to delete the managed object is also copied from the source object.

◆ operator ObjectType *()

template<class ObjectType>

OptionalScopedPointer< ObjectType >::operator ObjectType * ( ) const

noexcept

Returns the object that this pointer is managing.

◆ get()

template<class ObjectType>

ObjectType* OptionalScopedPointer< ObjectType >::get ( ) const

noexcept

Returns the object that this pointer is managing.

Referenced by SidePanel::getContent(), and SidePanel::getTitleBarComponent().

◆ operator*()

template<class ObjectType>

ObjectType& OptionalScopedPointer< ObjectType >::operator* ( ) const

noexcept

Returns the object that this pointer is managing.

◆ operator->()

template<class ObjectType>

ObjectType* OptionalScopedPointer< ObjectType >::operator-> ( ) const

noexcept

Lets you access methods and properties of the object that this pointer is holding.

◆ release()

template<class ObjectType>

ObjectType* OptionalScopedPointer< ObjectType >::release ( )

noexcept

Removes the current object from this OptionalScopedPointer without deleting it.

This will return the current object, and set this OptionalScopedPointer to a null pointer.

◆ reset()

template<class ObjectType>

void OptionalScopedPointer< ObjectType >::reset ( )

noexcept

Resets this pointer to null, possibly deleting the object that it holds, if it has ownership of it.

Referenced by OptionalScopedPointer< OutputStream >::clear(), OptionalScopedPointer< OutputStream >::set(), and OptionalScopedPointer< OutputStream >::~OptionalScopedPointer().

◆ clear()

template<class ObjectType>

void OptionalScopedPointer< ObjectType >::clear ( )

Does the same thing as reset().

◆ set()

template<class ObjectType>

void OptionalScopedPointer< ObjectType >::set	(	ObjectType *	newObject,
		bool	takeOwnership
	)

Makes this OptionalScopedPointer point at a new object, specifying whether the OptionalScopedPointer will take ownership of the object.

If takeOwnership is true, then the OptionalScopedPointer will act like a std::unique_ptr, deleting the object when it is itself deleted. If this parameter is false, then the OptionalScopedPointer just holds a normal pointer to the object, and won't delete it.

◆ setOwned()

template<class ObjectType>

void OptionalScopedPointer< ObjectType >::setOwned ( ObjectType * newObject )

Makes this OptionalScopedPointer point at a new object, and take ownership of that object.

Referenced by StandalonePluginHolder::showAudioSettingsDialog().

◆ setNonOwned()

template<class ObjectType>

void OptionalScopedPointer< ObjectType >::setNonOwned ( ObjectType * newObject )

Makes this OptionalScopedPointer point at a new object, but will not take ownership of that object.

◆ willDeleteObject()

template<class ObjectType>

bool OptionalScopedPointer< ObjectType >::willDeleteObject ( ) const

noexcept

Returns true if the target object will be deleted when this pointer object is deleted.

◆ swapWith()

template<class ObjectType>

void OptionalScopedPointer< ObjectType >::swapWith ( OptionalScopedPointer< ObjectType > & other )

noexcept

Swaps this object with another OptionalScopedPointer.

The two objects simply exchange their states.
