QString toString(int row, int column)

Get a value in data as a string using a provided row and column index.

• function definition:

  QString toString(int row, int column) const
  

• parameters:

  Parameter	Type	Description
  row	int	Row index of value
  column	int	Column index of value

• output: (QString) Returns the value stored at (row, column) as a string

• example:

  TemplateList targets = TemplateList() << Template("target1.jpg") << Template("target2.jpg") << Template("target3.jpg");
  TemplateList queries = TemplateList() << Template("query1.jpg") << Template("query2.jpg");
  
  MatrixOutput *output = MatrixOutput::make(targets, queries);
  output->set(10.0, 1, 2);
  output->toString(1, 2); // Returns "10"
  output->toString(2, 2); // ERROR: row index is out of range
  

void initialize(const FileList &targetFiles, const FileList &queryFiles)

Initialize the output. This function calls initialize which should be overloaded by derived classes that need to be initialized. After calling initialize, data is initialized to be of size queryFiles.size() x targetFiles.size().

• function definition:

  void initialize(const FileList &targetFiles, const FileList &queryFiles)
  

• parameters:

  Parameter	Type	Description
  targetFiles	const FileList &	List of target files for initialization
  queryFiles	const FileList &	List of query files for initialization

• output: (void)

void set(float value, int i, int j)

Set a value in data at the provided row and column indices.

• function definition:

  void set(float value, int i, int j)
  

• parameters:

  Parameter	Type	Description
  value	float	Value to be set
  i	int	Row index into data
  j	int	Column index into data

• output: (void)

• example:

  TemplateList targets = TemplateList() << Template("target1.jpg") << Template("target2.jpg") << Template("target3.jpg");
  TemplateList queries = TemplateList() << Template("query1.jpg") << Template("query2.jpg");
  
  MatrixOutput *output = MatrixOutput::make(targets, queries);
  output->set(6.0, 0, 1);
  output->toString(0, 1); // Returns "6.0"
  
  output->set(10.0, 1, 2);
  output->toString(1, 2); // Returns "10.0"
