Detailed Description

A base class that contains common methods used for parsing csv files.

CSVFileReaderBase is a base abstract class for reading csv files. It contains the methods GetDataDimension() which is used to count the number of rows and columns in the file data set. Only after this method is called should calls to the GetNextField() method be made. The method ConvertStringToValueType() can be used to convert a string obtained from GetNextField() to some desired numeric type. The Parse() method is what is used to do the full processing, that is, reading the file and parsing the data into some object. It is pure virtual as a different parsing method would be needed for parsing into different types of objects.

The user would need to specify if there are row and column headers in the file using the HasRowHeaders and HasColumnHeaders flags. Also, if row and/or column headers are enclosed in "" or any other string delimiter character being used, the user can set the option of turning the string delimiter character on with the UseStringDelimiterCharacter flag. This is also especially useful if headers such as "This,Header" contain commas or other field delimiter characters within them.

If the csv file has row and column headers, they do not necessarily need to be enclosed in "" or other string delimiter characters as long as you specify that row and/or column headers exist in the file. Turning on the HasRowHeaders or HasColumnHeaders flags will tell the reader to recognize them as headers.

The PrepareForParsing() method does not need to be called explicitly as it is called in the GetDataDimension() method.

Constructor & Destructor Documentation

itk::CSVFileReaderBase::CSVFileReaderBase ( )

Converting a string to other numeric value types. This is a template method in a non-templated class so it needs to be defined within the .h. The only way it would be possible to have the definition in the .cxx source file would be either to include the .cxx file or to use the export keyword, which will be removed from the c++ language.
