HDF5HeaderData Class Reference

#include <CH_HDF5.H>

List of all members.


Detailed Description

data to be added to HDF5 files.

HDF5HeaderData is a wrapper for some data maps to be added to HDF5 files. instead of an overdose of access functions, the maps are made public and they can be manipulated by the user at will. They maintain type safety.

to add a Real data entry, a user can simply program as follows:

   Real dx;   HDF5HeaderData metaData;
   metaData.m_real["dx"] = dx;
   

If "dx" already existed, then it is overwritten, otherwise an entry is created and added with the new value;

To search for entries, the user does the following:

   HDF5HeaderData metaData;
   HDF5Handle currentStep(filename);
   currentStep.setGroupToLevel(0);
   metaData.readFromFile(currentStep);
   if (metaData.m_intvect.find("ghost") != metaData.m_intvect.end())
   ghost = metaData.m_intvect["ghost"];
   else
   ghost = defaultGhostIntVect;

   

A user can skip the check for existence if they have reason to "know" the data will be there. It is just good coding practice.

To erase an entry, you can use:

   metaData.m_real.erase("dx");

Member Function Documentation

int HDF5HeaderData::writeToFile ( HDF5Handle file  )  const

Writes this HDF5HeaderData's current attribute list to the current group in 'file.' Returns 0 on success, returns the error code from HDF5 on failure.

Referenced by blockWrite(), blockWriteLevel(), write(), and writeLevel().

int HDF5HeaderData::readFromFile ( HDF5Handle file  ) 

Reads into this HDF5HeaderData's attribute list from file. Read process is add/change, does not remove key-value pairs. Reads from current group. Returns 0 on success, positive number if a particular member of group caused an error, negative on general error.
