Constructor Detail

Measurer

public Measurer()

A light constructor which initializes sorter.

Measurer

public Measurer(Sorter sorter)

A constructor which initializes sorter with the object given as argument.

Parameters:

sorter - the Sorter object to be used by the constructed Measurer.

Method Detail

measure

public List<Result> measure(Cell[][] data,
                            int column,
                            List<String> names)

Deprecated.

A shorthand for the full definition of measure(Cell[][], int, List, int, Order). Used for testing and debugging.

Parameters:

data - a 2-D array of type Cell to be sorted.

column - the index of the column which will be the sorting criteria.

names - a List of type String containing names of algorithms to be run and measured.

Returns:

a List of type Result holding information about the sorting runs.

measure

public List<Result> measure(Cell[][] data,
                            int column,
                            List<String> names,
                            int maxIter,
                            SortAlgorithm.Order order)

Method for running tests for different sorting algorithms. Runs a test for each name supplied. Possible names are "bubble", "insertion", "binaryInsertion", "selection", "merge", "quick", "counting".

Parameters:

data - a 2-D array of type Cell to be sorted.

column - the index of the column which will be the sorting criteria.

names - a List of type String containing names of algorithms to be run and measured.

maxIter - maximum number of iterations. Value of -1 means unlimited iterations, <-1 means none.

order - an enum Order (from SortAlgorithm) value determining the sorting direction.

Returns:

a List of type Result holding information about the sorting runs.
