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 ScopedPointer, but allows you to specify whether or not the object is deleted.
| OptionalScopedPointer< ObjectType >::OptionalScopedPointer | ( | ) |
Creates an empty OptionalScopedPointer.
| 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 ScopedPointer, 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< ObjectType >::OptionalScopedPointer | ( | OptionalScopedPointer< ObjectType > & | objectToTransferFrom | ) |
Takes ownership of the object that another OptionalScopedPointer holds.
Like a normal ScopedPointer, 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< ObjectType >::~OptionalScopedPointer | ( | ) |
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.
| OptionalScopedPointer& OptionalScopedPointer< ObjectType >::operator= | ( | OptionalScopedPointer< ObjectType > & | objectToTransferFrom | ) |
Takes ownership of the object that another OptionalScopedPointer holds.
Like a normal ScopedPointer, 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.

noexcept |
Returns the object that this pointer is managing.
|
noexcept |
Returns the object that this pointer is managing.
|
noexcept |
Returns the object that this pointer is managing.
|
noexcept |
Lets you access methods and properties of the object that this pointer is holding.
|
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.
| void OptionalScopedPointer< ObjectType >::clear | ( | ) |
Resets this pointer to null, possibly deleting the object that it holds, if it has ownership of it.

| 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 ScopedPointer, 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.
| void OptionalScopedPointer< ObjectType >::setOwned | ( | ObjectType * | newObject | ) |
Makes this OptionalScopedPointer point at a new object, and take ownership of that object.
Referenced by StandalonePluginHolder::showAudioSettingsDialog(), and OptionalScopedPointer< OutputStream >::swapWith().
| void OptionalScopedPointer< ObjectType >::setNonOwned | ( | ObjectType * | newObject | ) |
Makes this OptionalScopedPointer point at a new object, but will not take ownership of that object.
|
noexcept |
Returns true if the target object will be deleted when this pointer object is deleted.
|
noexcept |
Swaps this object with another OptionalScopedPointer.
The two objects simply exchange their states.
