Detailed Description

template<class T>
class HChunkWriter< T >

Takes a block of samples and writes it to the next writer in smaller chunks.

The chunksize must be an integral part of the incomming blocksize. Ex: Write(data, 4096) ==> Write(data, 1024) + Write(data+1024, 1024) + ...

Constructor & Destructor Documentation

HChunkWriter() [1/2]

template<class T >

HChunkWriter< T >::HChunkWriter ( )

inline

Construct a chunkwriter with chunk size 0 (zero). This will write all blocks straight through without chunking

HChunkWriter() [2/2]

template<class T >

HChunkWriter< T >::HChunkWriter ( int  chunksize )

inline

Construct a chunkwriter with the given chunk size

Member Function Documentation

Command()

template<class T >

virtual bool HChunkWriter< T >::Command ( HCommand *  command )

pure virtual

Receive, handle and propagate command

Returns: True if the command was executed correctly False otherwise. Errors is written to the error log

Implements HWriter< T >.

Implemented in HFftOutput< T >, HSignalLevelOutput< T >, and HGoertzelOutput< T >.

GetChunksize()

template<class T >

int HChunkWriter< T >::GetChunksize ( )

inline

Get the chunk size used by this writer

Write()

template<class T >

int HChunkWriter< T >::Write ( T *  src, size_t  blocksize  )

virtual

Write a block of samples

Implements HWriter< T >.

WriteChunk()

template<class T >

virtual int HChunkWriter< T >::WriteChunk ( T *  src, size_t  chunksize  )

pure virtual

Write a chunk of samples. This function must be implemented by classes inheriting the HChunkWriter class

Implemented in HOutput< T, O >, HOutput< T, HSignalLevelResult >, HOutput< T, HGoertzelResult >, and HOutput< T, HFftResults >.
