Default Sample implementation.

Member Function Documentation

addInfo()

void adtf_file::DefaultSample::addInfo ( uint32_t  key, DataType  type, uint64_t  raw_bytes  )

overridevirtual

Adds a additional sample information.

Parameters

key	key for the sample information
type	data type of the information
raw_bytes	the raw value of the information

Implements adtf_file::ReadSample.

beginBufferRead()

std::pair<const void*, size_t> adtf_file::DefaultSample::beginBufferRead ( ) const

overridevirtual

Retrieve a pointer to the memory buffer for user data and size in bytes.

Returns

std::pair<const void*, size_t>

Remarks

usually it shared locks the buffer, do not forget to call endBufferRead

Implements adtf_file::WriteSample.

beginBufferWrite()

void* adtf_file::DefaultSample::beginBufferWrite ( size_t  size )

overridevirtual

allocates the memory buffer for sample data

Parameters

size	the memory to allocate in bytes

Returns

void* the pointer to the memory

Remarks

usually it write locks the buffer, do not forget to call endBufferWrite

Implements adtf_file::ReadSample.

getContent()

template<typename T >

const T& adtf_file::DefaultSample::getContent ( ) const

inline

Get the Content of the sample for trivially copyable types.

Template Parameters

T	the type of the value trivially copyable

Returns

const T& reference to the value

getFlags()

uint32_t adtf_file::DefaultSample::getFlags ( ) const

overridevirtual

Get the Flags.

Returns

uint32_t

Implements adtf_file::WriteSample.

GetInfo()

const std::unordered_map<uint32_t, std::pair<DataType, uint64_t> >& adtf_file::DefaultSample::GetInfo

(

)

const

Get the additional sample information.

Returns

a reference to the unordered map with value key and a adtf_file::Datatype - raw value pair

getSubStreamId()

uint32_t adtf_file::DefaultSample::getSubStreamId ( ) const

overridevirtual

Get the Sub Stream Id if set.

Returns

uint32_t

Implements adtf_file::WriteSample.

getTimeStamp()

std::chrono::nanoseconds adtf_file::DefaultSample::getTimeStamp ( ) const

overridevirtual

Get the Time Stamp.

Returns

the time stamp of the sample

Implements adtf_file::WriteSample.

iterateInfo()

void adtf_file::DefaultSample::iterateInfo ( std::function< void(uint32_t key, DataType type, uint64_t raw_bytes)>  functor ) const

overridevirtual

iterates all additional data information (if any) by calling the functor

Parameters

functor

the function to call for each addition sample info value

Implements adtf_file::WriteSample.

setContent()

template<typename T >

void adtf_file::DefaultSample::setContent ( const T &  value )

inline

Set the Content of the sample for trivially copyable types.

Template Parameters

T	the type of the value trivially copyable

Parameters

value

the instance of T

setFlags()

void adtf_file::DefaultSample::setFlags ( uint32_t  flags )

overridevirtual

Set the Flags.

Parameters

flags

Implements adtf_file::ReadSample.

setSubStreamId()

void adtf_file::DefaultSample::setSubStreamId ( uint32_t  substream_id )

overridevirtual

Set the Sub Stream Id, if needed.

Parameters

substream_id

Implements adtf_file::ReadSample.

setTimeStamp()

void adtf_file::DefaultSample::setTimeStamp ( std::chrono::nanoseconds  time_stamp )

overridevirtual

Set the Time Stamp.

Parameters

time_stamp

Implements adtf_file::ReadSample.
