Construct2DupL(MCameraObserver &, TInt)

void	Construct2DupL	(	MCameraObserver &	aObserver,
			TInt	aCameraHandle
		)	[protected, pure virtual]

A call to one of the factory functions firstly loads the plugin, followed by a call to this function to complete construction.

Duplicates the original camera object for use by, for example, multimedia systems.

May leave with KErrNoMemory or KErrNotFound if aCameraHandle is not valid.

Parameters

MCameraObserver & aObserver	Reference to an observer.
TInt aCameraHandle	Handle of an existing camera object.

Construct2DupL(MCameraObserver2 &, TInt)

void	Construct2DupL	(	MCameraObserver2 &	aObserver,
			TInt	aCameraHandle
		)	[protected, pure virtual]

A call to one of the factory functions firstly loads the plugin, followed by a call to this function to complete construction.

Duplicates the original camera object for use by, for example, multimedia systems.

May leave with KErrNoMemory or KErrNotFound if aCameraHandle is not valid.

leave: May leave with KErrNoMemory or KErrNotFound if aCameraHandle is not valid.

Parameters

MCameraObserver2 & aObserver	Reference to an observer.
TInt aCameraHandle	Handle of an existing camera object.

Construct2L(MCameraObserver &, TInt)

void	Construct2L	(	MCameraObserver &	aObserver,
			TInt	aCameraIndex
		)	[protected, pure virtual]

A call to one of the factory functions firstly loads the plugin, followed by a call to this function to complete construction.

Creates an object representing a camera.

leave: May leave with KErrNoMemory or KErrNotSupported if aCameraIndex is out of range.

Parameters

MCameraObserver & aObserver	Reference to class derived from MCameraObserver2 designed to receive notification of asynchronous event completion.
TInt aCameraIndex	Index from 0 to CamerasAvailable()-1 inclusive specifying the camera device to use.

Construct2L(MCameraObserver2 &, TInt, TInt)

void	Construct2L	(	MCameraObserver2 &	aObserver,
			TInt	aCameraIndex,
			TInt	aPriority
		)	[protected, pure virtual]

A call to one of the factory functions firstly loads the plugin, followed by a call to this function to complete construction.

Creates an object representing a camera.

leave: May leave with KErrNoMemory or KErrNotSupported if aCameraIndex is out of range.

Parameters

MCameraObserver2 & aObserver	Reference to class derived from MCameraObserver2 designed to receive notification of asynchronous event completion.
TInt aCameraIndex	Index from 0 to CamerasAvailable()-1 inclusive specifying the camera device to use.
TInt aPriority	Value from -100 to 100 indicating relative priority of client to use camera.
