Detailed Description

For reading DCO objects elements from a HDF file.

Elements can contain either scalars, fixed-length vectors or variable length vectors of data. From a base path, each element gets a dataset with its name.

Member Function Documentation

getTick()

TimeTickType dueca::hdf5log::HDF5DCOReadFunctor::getTick

(

bool

nextrow = false

)

Local function to flush/write and prepare for next present data.

Parameters

nextrow

If true; and advance the index, so that a next getTick will read new data.

Returns

Time associated with the current data row

Member Data Documentation

sets

std::vector<LogDataSet> dueca::hdf5log::HDF5DCOReadFunctor::sets

protected

One set per element/member of the DCO object.

If applicable, the last set is for the time tick.
