◆ getDomainReadType()

virtual ErrCode INTERFACE_FUNC getDomainReadType ( SampleType * sampleType )

pure virtual

Gets the sample-type the signal domain samples will be converted to when read or SampleType::Invalid if read-type has not been determined yet.

Parameters

[out] sampleType The sample-type type of the read samples otherwise SampleType::Invalid.

◆ getReadMode()

virtual ErrCode INTERFACE_FUNC getReadMode ( ReadMode * mode )

pure virtual

Gets the reader's read mode which determines if the reader will also scale the read data or not.

Parameters

[out] mode The mode the reader is in (either Raw or Scaled)

◆ getValueReadType()

virtual ErrCode INTERFACE_FUNC getValueReadType ( SampleType * sampleType )

pure virtual

Gets the sample-type the signal value samples will be converted to when read or SampleType::Invalid if read-type has not been determined yet.

Parameters

[out] sampleType The sample-type type of the read samples otherwise SampleType::Invalid.

◆ setDomainTransformFunction()

virtual ErrCode INTERFACE_FUNC setDomainTransformFunction ( IFunction * transform )

pure virtual

Sets the transform function that will be called with the read domain-data and currently valid Signal-Descriptor giving the user the chance add a custom post-processing step. The function should have a signature compatible with:

transform(Int inputBuffer, Int outputBuffer, SizeT toRead, IDataDescriptor* descriptor)

Parameters

transform The function performing the post-processing.

◆ setValueTransformFunction()

virtual ErrCode INTERFACE_FUNC setValueTransformFunction ( IFunction * transform )

pure virtual

Sets the transform function that will be called with the read value-data and currently valid Signal-Descriptor giving the user the chance add a custom post-processing step. The function should have a signature compatible with:

transform(Int inputBuffer, Int outputBuffer, SizeT toRead, IDataDescriptor* descriptor)

Parameters

transform The function performing the post-processing.

	openDAQ Open data acquisition platform
