Implementation of Reference object. More...

Go to the source code of this file.

Data Structures
struct	tivx_reference_t
	The most basic type in the OpenVX system. Any type that inherits from tivx_reference_t must have a vx_reference_t as its first memeber to allow casting to this type. More...

Typedefs
typedef vx_status(*	tivx_reference_callback_f) (vx_reference ref)
	Callback type used to register different callbacks from object dervied from references.
typedef vx_status(*	VX_API_CALL) (vx_reference *ref)
	Callback type used to register release callbacks from object dervied from references.

Enumerations
enum	tivx_reftype_e
	An internal enum for notating which sort of reference type we need.

Functions
vx_reference	ownCreateReference (vx_context context, vx_enum type, vx_enum reftype, vx_reference scope)
	Create a reference object. More...
vx_status	ownReleaseReferenceInt (vx_reference *ref, vx_enum type, vx_enum reftype, tivx_reference_callback_f destructor)
	Used to destroy a reference. More...
vx_bool	ownIsValidSpecificReference (vx_reference ref, vx_enum type)
	Used to validate everything but vx_context, vx_image. More...
vx_status	ownReferenceLock (vx_reference ref)
	Lock the reference. More...
vx_status	ownReferenceUnlock (vx_reference ref)
	Unlock the reference. More...
vx_uint32	ownIncrementReference (vx_reference ref, vx_enum reftype)
	Increments the ref count. More...
vx_uint32	ownDecrementReference (vx_reference ref, vx_enum reftype)
	Decrements the ref count. More...
vx_uint32	ownTotalReferenceCount (vx_reference ref)
	Returns the total reference count of the object. More...
void	ownPrintReference (vx_reference ref)
	Print reference information. More...
vx_bool	ownIsValidType (vx_enum type)
	This returns true if the type is within the definition of types in OpenVX. More...
vx_status	ownInitReference (vx_reference ref, vx_context context, vx_enum type, vx_reference scope)
	Init a reference object. More...
vx_bool	ownIsValidReference (vx_reference ref)
	Check if reference is valid. More...
void	ownInitReferenceForDelay (vx_reference ref, vx_delay d, vx_int32 index)
	Used to initialize any vx_reference as a delay element. More...
vx_status	ownReferenceAllocMem (vx_reference ref)
	Alloc memory associated with this reference, typically data reference.
vx_size	ownSizeOfEnumType (vx_enum item_type)
	Get the size of the Type enum.
void	ownReferenceSetScope (vx_reference ref, vx_reference scope)
	Set scope of a reference.
vx_reference	ownReferenceGetHandleFromObjDescId (uint16_t obj_desc_id)
	Return reference given a obj desc ID This API must only be called on the host Use the ownReferenceGetHostRefFromObjDescId if needing to call from the remote cores.
uint64_t	ownReferenceGetHostRefFromObjDescId (uint16_t obj_desc_id)
	Return 64 bit reference given a obj desc ID Used to call on the remote cores.
