Public Member Functions | |
| HRESULT | Initialize ([in, ref] aafUID_constref id,[in, string] aafCharacter_constptr pName,[in, string] aafCharacter_constptr pDescription) |
| Init all fields of a definition object. | |
| HRESULT | AddParentProperty ([in] IAAFPropertyDef *pParentProperty) |
| Add a property definition to the KLV data definition. | |
| HRESULT | GetParentProperties ([out] IEnumAAFPropertyDefs **ppEnum) |
| Writes an enumerator for the property definitions into *ppEnum. | |
| HRESULT | CountParentProperties ([out] aafUInt32 *pNumProperties) |
| Writes the total number of property definitions into *pNumProperties if, and only if, the method succeeds. | |

This interface is used to describe the data type of a value stored in an AAFKLVData object.
Objects that implement IAAFKLVDataDefinition also implement the following interfaces:
| HRESULT IAAFKLVDataDefinition::AddParentProperty | ( | [in] IAAFPropertyDef * | pParentProperty | ) |
Add a property definition to the KLV data definition.
Return codes:
AAFRESULT_SUCCESS
AAFRESULT_NULL_PARAM
| pParentProperty | [in] Property definition to add. |
| HRESULT IAAFKLVDataDefinition::CountParentProperties | ( | [out] aafUInt32 * | pNumProperties | ) |
Writes the total number of property definitions into *pNumProperties if, and only if, the method succeeds.
Return codes:
AAFRESULT_SUCCESS
AAFRESULT_NULL_PARAM
| pNumProperties | [out] Number of property definitions. |
| HRESULT IAAFKLVDataDefinition::GetKLVDataType | ( | [out] IAAFTypeDef ** | ppTypeDef | ) |
Writes the data definition object attached to this KLV data definition into the *ppTypeDef argument if, and only if, the call succeeds.
If none exists, NULL is written to the *ppTypeDef argument.
The returned data definition object, if it exists, is AddRef()ed before it is returned.
Return codes:
AAFRESULT_SUCCESS
AAFRESULT_NULL_PARAM
| ppTypeDef | [out] Returned data definition object |
| HRESULT IAAFKLVDataDefinition::GetParentProperties | ( | [out] IEnumAAFPropertyDefs ** | ppEnum | ) |
Writes an enumerator for the property definitions into *ppEnum.
A reference is added to the new enumerator before it is returned.
Return codes:
AAFRESULT_SUCCESS
AAFRESULT_NULL_PARAM
| ppEnum | [out] Property definition enumerator. |
| HRESULT IAAFKLVDataDefinition::Initialize | ( | [in, ref] aafUID_constref | id, |
| [in, string] aafCharacter_constptr | pName, | ||
| [in, string] aafCharacter_constptr | pDescription | ||
| ) |
Init all fields of a definition object.
| id | [in, ref] AUID for new DefObject |
| pName | [in, string] Name for new DefObject |
| pDescription | [in, string] Description for new DefObject |
| HRESULT IAAFKLVDataDefinition::RemoveParentProperty | ( | [in] IAAFPropertyDef * | pParentProperty | ) |
Removes the given property definition.
Return codes:
AAFRESULT_SUCCESS
AAFRESULT_NULL_PARAM
AAFRESULT_NO_MORE_OBJECTS
| pParentProperty | [in] Property to remove. |
| HRESULT IAAFKLVDataDefinition::SetKLVDataType | ( | [in] IAAFTypeDef * | pTypeDef | ) |
Sets the date type of this KLV data definition to be the given one.
Return codes:
AAFRESULT_SUCCESS
AAFRESULT_NULL_PARAM
| pTypeDef | [in] Data definition object |
