OECSVHeader

class OECSVHeader

This class stores the column names to be read or written to a OEFormat_CSV file. It is typically retrieved from an oemolstreambase through the oemolstreambase.GetCSVHeader method. The object available from that method is initialized during the first read or write operation on that stream.

Constructors

OECSVHeader()
OECSVHeader(const OECSVHeader &rhs)
OECSVHeader(const std::vector<std::string> &columnNames)

The default constructors initializes the object to an empty state. The copy constructor can be used to make a copy from about OECSVHeader object. The class can also be constructed directly from a std::vector of std::string.

operator=

OECSVHeader &operator=(const OECSVHeader &rhs)

Assignment operator to copy the contents of rhs into this class.

operator bool

operator bool() const

Returns false if this class has not been initialized with any column names yet. Returns true if this class does contain column names.

Clear

void Clear()

Resets the class to an empty uninitialized state.

GetColumnName

const std::string &GetColumnName(unsigned int fieldIdx) const

Return the column name for the particular index, starting at zero. If fieldIdx is not less than OECSVHeader.GetNumColumns, a reference to an empty string is returned.

GetColumnNames

OESystem::OEIterBase<const std::string> *GetColumnNames() const

Returns an iterator over all the column names stored in this class.

GetNumColumns

unsigned int GetNumColumns() const

Returns the number of column names stored in this class.

IsValid

bool IsValid() const

Returns false if this class has not been initialized with any column names yet. Returns true if this class does contain column names.
