Method Detail

createArray

public java.lang.Integer[] createArray(DriverInterface.ArrayType arrayType,
                                       int arraySize)

Description copied from interface: DriverInterface

This method is used to create a new array of Integer objects of the type and size specified.

Specified by:

createArray in interface DriverInterface

Parameters:

arrayType - This parameter specifies the type of array to create. See the enum DriverInterface.ArrayType.

arraySize - This parameter specifies the size of array to create.

Returns:

The method will return the array of Integer objects that was created.

run

public void run(SortInterface<java.lang.Integer> si,
                DriverInterface.ArrayType arrayType,
                int arraySize,
                int numberOfTimes)

runSorts

public TestTimes[] runSorts(DriverInterface.ArrayType arrayType,
                            int arraySize,
                            int numberOfTimes)

Description copied from interface: DriverInterface

This method will run all the possible sorts a specified number of times. Each time a sort is run, the method will obtain a new array to sort. The array will be of the specified type and size.

Specified by:

runSorts in interface DriverInterface

Parameters:

arrayType - This parameter specifies the type of array to create each time the sort is run. See the enum DriverInterface.ArrayType.

arraySize - This parameter specifies the size of array to create each time the sort is run.

numberOfTimes - This parameter specifies the number of times to run the specified sort.

Returns:

The method must return an array of TestTimes instances. The array will contain the following instances in the order specified below: *

1. MergeSort
2. QuickSort PivotType.FirstElement
3. QuickSort PivotType.RandomElement
4. QuickSort PivotType.MidOfFirstMidLastElement
5. HeapSort
