Member Function Documentation

getDomainReadType()

daq::SampleType getDomainReadType ( ) const

inline

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.

Returns

The sample-type type of the read samples otherwise SampleType::Invalid.

getReadMode()

daq::ReadMode getReadMode ( ) const

inline

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

Returns

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

getValueReadType()

daq::SampleType getValueReadType ( ) const

inline

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.

Returns

The sample-type type of the read samples otherwise SampleType::Invalid.

setDomainTransformFunction()

void setDomainTransformFunction ( const daq::FunctionPtr &  transform ) const

inline

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()

void setValueTransformFunction ( const daq::FunctionPtr &  transform ) const

inline

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.
