Hi,
Here's my problem:
I have to read a dataset (HDF5 Compund DataSet)
ex:
label size needComputation dataArray
1 200 0 {222, 222.5, 223, 223.5,...}
3 100 1 {710, 712, 724, 756,...}
8 2 1 {3.753, 0}
to this structure:
typedef struct
{
unsigned int label;
unsigned long long size;
bool needComputation;
double* dataArray;
} my_data_type;
I can read label, size, needComputation but not dataArray which is a
Variable-length of 64-bit floating-point.
For bool type I use:
EnumType boolEnumType(sizeof(bool));
bool falseValue = 0;
bool trueValue = 1;
boolEnumType.insert("FALSE", &falseValue);
boolEnumType.insert("TRUE", &trueValue);
// compound type
CompType mtype( sizeof(my_data_type) );
mtype.insertMember( "Label", HOFFSET(my_data_type, label),
PredType::NATIVE_UINT);
mtype.insertMember( "size", HOFFSET(my_data_type, size),
PredType::NATIVE_UINT64);
mtype.insertMember( "NeedComputation", HOFFSET(my_data_type, isEven),
boolEnumType);
//mtype.insertMember( "DataArray", HOFFSET(my_data_type, dataArray),
PredType::H5T_IEEE_F64LE);
// This last line give me: CompType::insertMember H5Tinsert failed
DataSpace ds = dataset.getSpace();
hssize_t n = sid1.getSimpleExtentNpoints();
my_data_type* mdt = new my_data_type[n];
dataset.read( mdt, mtype);
for( int i = 0; i < n; i++)
{
cout <<"label " << mdt[i].label << " size "<< mdt[i].size << "
needComputation "<< mdt[i].needComputation << endl;
}
delete[] mdt;
-----------------
So, how can I read "dataArray" of double and know the size of this array ?
I haven't find any example about this in c++.
Thank you for your help._______________________________________________
