Detailed Description

template<class TData>
class itk::CSVArray2DFileReader< TData >

Parses csv files and stores the data in a itkCSVArray2DDataObject.

CSVArray2DFileReader is used for reading csv files. This reader should only be used for parsing numeric data fields. The Parse() method in this class parses the data from the file into a itkCSVArray2DDataObject. As the Array2D object only holds one data type, all the data, other than the row and column headers, will be cast to a single data type. Row and column headers will be parsed into std vectors of strings.

The user would need to specify the file name using the SetFileName() method. The field delimiter character is set to ',' by default but other field delimiter characters may be set using SetFieldDelimiterCharacter(). If there are row and column headers in the file, the user must specify whether or not they exist using the HasRowHeaders and HasColumnHeaders flags. Also, if row and/or column headers are enclosed in "" or within other string delimiter characters 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 HasColumnHeaders flags will tell the reader that the first line contains column headers and turning on HasRowHeaders will tell the reader to recognize the first field in all subsequent lines as row headers. After all the inputs have been set, the user then calls the Parse() method. The user can then get the results by instantiating a itkCSVArray2DDataObject and assigning it using the GetOutput() method.

Below is an example of how this class can be used to read and parse the data from an input file:

typedef itk::CSVArray2DFileReader<double> ReaderType; ReaderType::Pointer reader = ReaderType::New();

std::string filename = "NameOfFile.csv"; reader->SetFileName( filename ); reader->SetFieldDelimiterCharacter( ',' ); reader->SetStringDelimiterCharacter( '"' ); reader->HasColumnHeadersOn(); reader->HasRowHeadersOn(); reader->UseStringDelimiterCharacterOn();

reader->Parse();

virtual::itk::LightObject::Pointer itk::CSVArray2DFileReader< TData >::CreateAnother ( void  ) const

virtual

Create an object from an instance, potentially deferring to a factory. This method allows you to create an instance of an object that is exactly the same type as the referring object. This is useful in cases where an object has been cast back to a base class.

Reimplemented from itk::LightProcessObject.

template<class TData >

virtual Array2DDataObjectType* itk::CSVArray2DFileReader< TData >::GetArray2DDataObject ( )

virtual

This method can be used to get the data frame object once the data from the file has been parsed.
