HRESULT IAAFInterpolator::GetIndexedSupportedType (  [in] aafUInt32  index, [out] IAAFTypeDef **  ppType )

Parameters: index  [in] Which flavour to get the ID for ppType  [out] The returned type definition

HRESULT IAAFInterpolator::GetNumTypesSupported (  [out] aafUInt32 *  pCount  )

Parameters: pCount  [out] Number of data types supported

HRESULT IAAFInterpolator::GetParameter (  [out] IAAFParameter **  ppParameter  )

Places the parameter object attached to this interpolator into the ppParameter argument. If none exists yet, NULL is placed into the ppParameter argument. The returned parameter object, if it exists, is AddRef()ed before it is returned. Succeeds if all of the following are true: the ppParameter pointer is valid. A valid data definition exists. This method will return the following codes. If more than one of the listed errors is in effect, it will return the first one encountered in the order given below: AAFRESULT_SUCCESS succeeded. (This is the only code indicating success.) AAFRESULT_NULL_PARAM ppParameter is null. Parameters: ppParameter  [out] Returned data definition object

HRESULT IAAFInterpolator::GetTypeDefinition (  [out] IAAFTypeDef **  ppTypeDef  )

Places the data definition object attached to this interpolator into the ppTypeDef argument. If none exists yet, NULL is placed into the ppTypeDef argument. The returned data definition object, if it exists, is AddRef()ed before it is returned. Succeeds if all of the following are true: the ppTypeDef pointer is valid. A valid data definition exists. This method will return the following codes. If more than one of the listed errors is in effect, it will return the first one encountered in the order given below: AAFRESULT_SUCCESS succeeded. (This is the only code indicating success.) AAFRESULT_NULL_PARAM ppTypeDef is null. Parameters: ppTypeDef  [out] Returned data definition object

HRESULT IAAFInterpolator::InterpolateMany (  [in] aafRational_t *  pStartInputValue, [in] aafRational_t *  pInputStep, [in] aafUInt32  generateCount, [out] aafMemPtr_t  pOutputValue, [out] aafUInt32 *  pResultCount )

Succeeds if all of the following are true: - the pInputValue pointer is valid. the pInputStep pointer is valid. the ppOutputValue pointer is valid. the pResultCount pointer is valid. The input value is between 0 (effect start), to 1 (effect end) inclusive. This method will return the following codes. If more than one of the listed errors is in effect, it will return the first one encountered in the order given below: AAFRESULT_SUCCESS succeeded. (This is the only code indicating success.) AAFRESULT_INPUT_RANGE The input value must be between 0 and 1, inclusive. AAFRESULT_NULL_PARAM pInputValue or ppOutputValue or pInputStep or pResultCount is null. Parameters: pStartInputValue  [in] Input values are from 0 (effect start), to 1 (effect end) inclusive. pInputStep  [in] Amount to add to *pStartInputValue to get the next point to interpolate generateCount  [in] The number of points to interpolate pOutputValue  [out] an array of generated control points pResultCount  [out] The number of points actually generated

HRESULT IAAFInterpolator::InterpolateOne (  [in] aafRational_t *  pInputValue, [in] aafUInt32  valueSize, [out, size_is(valueSize), length_is(*bytesRead)] aafDataBuffer_t  pValue, [out] aafUInt32 *  bytesRead )

Succeeds if all of the following are true: - the pInputValue pointer is valid. the ppOutputValue pointer is valid. The input value is between 0 (effect start), to 1 (effect end) inclusive. This method will return the following codes. If more than one of the listed errors is in effect, it will return the first one encountered in the order given below: AAFRESULT_SUCCESS succeeded. (This is the only code indicating success.) AAFRESULT_INPUT_RANGE The input value must be between 0 and 1, inclusive. AAFRESULT_NULL_PARAM pInputValue or ppOutputValue is null. Parameters: pInputValue  [in] Input values are from 0 (effect start), to 1 (effect end) inclusive. valueSize  [in] Size of preallocated buffer pValue  [out, size_is(valueSize),length_is(*bytesRead)] A generated control point bytesRead  [out] The number of bytes actually transferred

HRESULT IAAFInterpolator::SetParameter (  [in] IAAFParameter *  pParameter  )

Sets the parmeter of this interpolator to be the given one. Succeeds if all of the following are true: the pParameter pointer is valid. This method will return the following codes. If more than one of the listed errors is in effect, it will return the first one encountered in the order given below: AAFRESULT_SUCCESS succeeded. (This is the only code indicating success.) AAFRESULT_NULL_PARAM pParameter is null. Parameters: pParameter  [in] Parameter object

HRESULT IAAFInterpolator::SetTypeDefinition (  [in] IAAFTypeDef *  pTypeDef  )

Sets the data definition of this interpolator to be the given one. Succeeds if all of the following are true: the pTypeDef pointer is valid. This method will return the following codes. If more than one of the listed errors is in effect, it will return the first one encountered in the order given below: AAFRESULT_SUCCESS succeeded. (This is the only code indicating success.) AAFRESULT_NULL_PARAM pTypeDef is null. Parameters: pTypeDef  [in] Data definition object
