Member Function Documentation

int addColumn ( const std::string &  label,
const std::vector< double > &  data,
const std::vector< intptr_t > &  shape 
)
virtualinherited

Adds column vector.

Adds a new column with label and returns its index. The number of rows, as defined by first element of the shape, must be the same as existing columns, if any. Not all derived classes support the notion of shape, therefore as convenience to developers, the implementation in this base class throws a std::runtime_error object.

Reimplemented in FitsNTuple.

Definition at line 400 of file DataSource.cxx.

int addColumn ( const std::string &  label,
const std::vector< double > &  data 
)
virtualinherited

Adds column vector.

If implemented in a derived class, adds a new column with label and returns its index.

Note
Not all derived classes support the notion of adding columns. The implementation in this base class throws a std::runtime_error object if called.

Reimplemented in NTuple, RootNTuple, FitsNTuple, QtRootNTuple, and PyNTuple.

Definition at line 390 of file DataSource.cxx.

void addObserver ( hippodraw::Observer observer)
inherited
void addRow ( const std::vector< double > &  v)
virtual

Adds a row to the end of the ntuple.

If the size of the input vector is the same as the width of the ntuple, adds the row to the end of the ntuple. It also notifies its Observer objects and returns true. Otherwise, throws a DataSourceException object.

Reimplemented from DataSource.

References RTuple::m_data, and DataSource::throwIfInvalidRowSize().

void append ( const DataSource source)
