Package com.github.rlacher.sortbench.sorter

Class Sorter

java.lang.Object

com.github.rlacher.sortbench.sorter.Sorter

public class Sorter
extends Object

Context class for sorting algorithms, utilising the Strategy design pattern.

This class encapsulates the sorting logic, delegating the actual sorting operation to a SortStrategy. This allows for dynamic switching of sorting algorithms at runtime.

For simplicity at this project scale, the Sorter class directly acts as the Strategy pattern's context, rather than using a separate interface.

The sorter centralises argument validation to ensure data integrity.

Sorter

public Sorter()

Constructs a default instance of Sorter.

This constructor performs no custom initialisation.

Method Details

setStrategy

public void setStrategy(SortStrategy sortStrategy)

Sets the sorting strategy to be used.

Parameters:

sortStrategy - The sorting strategy to be used.

Throws:

IllegalArgumentException - If the sort strategy is null.

sort

public BenchmarkMetric sort(int[] array)

Validates the input array and delegates the sorting task to the currently set SortStrategy.

Requires a prior call to setStrategy(com.github.rlacher.sortbench.strategies.SortStrategy).

Parameters:

array - The array to be sorted.

Returns:

Returns a BenchmarkMetric with the metric value for the Benchmarker.ProfilingMode. Returns 0 if the array is empty.
