	Import (vx_context context, vx_reference scope)
	Construct a new Import object.
	~Import ()
	Destroy the Import object.
vx_uint32	refCount () const
	Returns the reference count of the object.
vx_enum	dataType () const
	Returns the type of the reference.
const vx_char *	refName () const
	Returns the name of the reference.
void	setName (const vx_char *name)
	Sets the name of the reference.
vx_uint32	incrementReference (vx_reftype_e refType)
	Increments the ref count.
vx_uint32	decrementReference (vx_reftype_e refType)
	Decrements the ref count.
vx_uint32	totalReferenceCount ()
	Returns the total reference count of the object.
void	initReferenceForDelay (vx_delay delay, vx_int32 index)
	Used to initialize any vx_reference as a delay element.
virtual void	destruct ()
	Destruct reference.

Static Public Member Functions
static vx_reference	createReference (vx_context context, vx_enum type, vx_reftype_e refType, vx_reference scope)
	Used to create a reference.
static void	printReference (vx_reference ref)
	Prints the values of a reference.
static vx_bool	isValidReference (vx_reference ref)
	Used to validate everything but vx_context, vx_image and vx_buffer.
static vx_bool	isValidReference (vx_reference ref, vx_enum type)
	Used to validate everything but vx_context, vx_image and vx_buffer.
static vx_size	sizeOfType (vx_enum type)
	Returns the number of bytes in the internal structure for a given type.
static vx_status	releaseReference (vx_reference *ref, vx_enum type, vx_reftype_e reftype, vx_destructor_f special_destructor)
	Used to destroy a reference.

Public Attributes
vx_enum	import_type
	The internal representation of any import object.
vx_uint32	count
	The number of references in the import.
vx_reference *	refs
	The set of references in the import.
struct _vx_platform *	platform
	Platform for ICD compatibility.
vx_uint32	magic
	Used to validate references, must be set to VX_MAGIC.
vx_enum	type
	Set to an enum value in vx_type_e.
vx_context	context
	Pointer to the top level context. If this reference is the context, this will be NULL.
vx_reference	scope
	The pointer to the object's scope parent. When virtual objects are scoped within a graph, this will point to that parent graph. This is left generic to allow future scoping variations. By default scope should be the same as context.
vx_uint32	external_count
	The count of the number of users with this reference. When greater than 0, this can not be freed. When zero, the value can be considered inaccessible.
vx_uint32	internal_count
	The count of the number of framework references. When greater than 0, this can not be freed.
vx_uint32	read_count
	The number of times the object has been read (in some portion)
vx_uint32	write_count
	The number of times the object has been written to (in some portion)
vx_sem_t	lock
	The reference lock which is used to protect access to "in-fly" data.
void *	reserved
	A reserved field which can be used to store anonymous data.
vx_uint32	index
	A field which can be used to store a temporary, per-graph index.
vx_bool	extracted
	This indicates if the object was extracted from another object.
vx_bool	is_virtual
	This indicates if the object is virtual or not.
vx_delay	delay
vx_int32	delay_slot_index
vx_bool	is_accessible
	This indicates that if the object is virtual whether it is accessible at the moment or not.
vx_char	name [VX_MAX_REFERENCE_NAME]
	The reference name.

count

vx_uint32 coreflow::Import::count

The number of references in the import.

delay

vx_delay coreflow::Reference::delay

inherited

vx_uint32 coreflow::Reference::external_count

inherited

The count of the number of users with this reference. When greater than 0, this can not be freed. When zero, the value can be considered inaccessible.
