// description : This utility class helps to allocate and desallocate READ attributes
// as POGO only generates pointers and let the Device developper manage memory allocation
//
// Note : these functions also initialise to a default value the allocated attributes
// Usage examples :
//
// CREATE_SCALAR_ATTRIBUTE(attr_hCoordinate_read); // by default initialised to 0
// CREATE_SCALAR_ATTRIBUTE(attr_hCoordinate_read,1); // initialised to 1
// DELETE_SCALAR_ATTRIBUTE(attr_hCoordinate_read)
//
// CREATE_DEVSTRING_ATTRIBUTE(attr_currentUMatrix_read,MAX_STRING_LENGTH);// by default initialised to ""
// CREATE_DEVSTRING_ATTRIBUTE(attr_currentUMatrix_read,MAX_STRING_LENGTH,"No U Matrix available");
// DELETE_DEVSTRING_ATTRIBUTE(attr_currentUMatrix_read)
//
// CREATE_SPECTRUM_ATTRIBUTE(attr_currentspectrum_read,MAX_LENGTH);// by default initialised to 0
// CREATE_SPECTRUM_ATTRIBUTE(attr_currentspectrum_read,MAX_LENGTH, 1);
// DELETE_SPECTRUM_ATTRIBUTE(attr_currentspectrum_read);
//-----------------------------------------------------------------------------

// Usage : DELETE_SCALAR_ATTRIBUTE(attr_hCoordinate_read);
