Detailed Description

Abstract class for data types.

Use this class to define a custom data type. Data types ares used for logging and graphs.
The reimplemented class must call SetSize() in its constructor.
io_data can be constructed with n samples (see io_data::io_data). In this case, old samples can be accessed throug io_data::Prev.

Constructor & Destructor Documentation

flair::core::io_data::io_data ( const Object parent,
std::string  name,

Member Function Documentation

void flair::core::io_data::SetDataTime ( Time  time)

Set data time.

Time flair::core::io_data::DataTime ( void  ) const

Data time.

data time
const io_data* flair::core::io_data::Prev ( int  n) const

Previous data.

Access previous data. io_data must have been constructed with n>1, io_data::SetPtrToCircle must have been set and io_data::prev must have been allocated.

void flair::core::io_data::AppendLogDescription ( std::string  description,
DataType const &  datatype 

Specify the description of the reimplemented class data's.

This method must be called in the constructor of the reimplemented class, once by element.
Each element description must be called in the same order as CopyDatas put the datas in the buffer.
The description will be used for the log descriptor file.

void flair::core::io_data::SetPtrToCircle ( void **  ptr)

Set the datas to circle.

ptrpointer to the data to circle

Member Data Documentation

io_data* flair::core::io_data::prev

Pointer to previous data.

Reimplemented class must allocate this pointer if n>1.
Pointer must be allocated with the same kind of reimplemented class.
