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 member 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 derived from references. | |
typedef vx_status(* | VX_API_CALL) (vx_reference *ref) |
Callback type used to register release callbacks from object derived 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 ref_type, vx_enum reftype, vx_reference scope) |
Create a reference object. More... | |
vx_status | ownReleaseReferenceInt (vx_reference *ref, vx_enum ref_type, vx_enum reftype, tivx_reference_callback_f destructor) |
Used to destroy a reference. More... | |
vx_bool | ownIsValidSpecificReference (vx_reference ref, vx_enum ref_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_bool | ownIsValidType (vx_enum ref_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 ref_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 idx) |
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. | |
vx_status | ownAllocReferenceBufferGeneric (vx_reference ref) |
There are several reference types that are allocated in the same way This API generalizes this in order to enhance code reuse The API will allocate the data buffer memory associated with the data object and release the associated object descriptor This API must only be called on the host. | |
vx_status | ownDestructReferenceGeneric (vx_reference ref) |
There are several reference types that are destructed in the same way This API generalizes this in order to enhance code reuse The API will free the data buffer memory associated with the data object and release the associated object descriptor This API must only be called on the host. | |
