Method Detail

instance

public static <ELEMENT> Object2DArrays<ELEMENT> instance()

Returns the singleton instance of this class.

Type Parameters:

ELEMENT - the type of elements of the 2D array.

Returns:

the singleton instance of this class.

assertNullOrEmpty

public void assertNullOrEmpty(AssertionInfo info,
                              ELEMENT[][] actual)

Asserts that the given array is null or empty.

Parameters:

info - contains information about the assertion.

actual - the given array.

Throws:

AssertionError - if the given array is not null *and* contains one or more elements.

assertEmpty

public void assertEmpty(AssertionInfo info,
                        ELEMENT[][] actual)

Asserts that the given array is empty.

Parameters:

info - contains information about the assertion.

actual - the given array.

Throws:

AssertionError - if the given array is null.

AssertionError - if the given array is not empty.

assertNotEmpty

public void assertNotEmpty(AssertionInfo info,
                           ELEMENT[][] actual)

Asserts that the given array is not empty.

Parameters:

info - contains information about the assertion.

actual - the given array.

Throws:

AssertionError - if the given array is null.

AssertionError - if the given array is empty.

assertHasDimensions

public void assertHasDimensions(AssertionInfo info,
                                ELEMENT[][] actual,
                                int expectedFirstDimension,
                                int expectedSecondDimension)

Asserts that the number of elements in the given array is equal to the expected one.

Parameters:

info - contains information about the assertion.

actual - the given array.

expectedFirstDimension - the expected first dimension size of actual.

expectedSecondDimension - the expected second dimension size of actual.

Throws:

AssertionError - if the given array is null.

AssertionError - if the actual array's dimensions are not equal to the given ones.

assertHasSameDimensionsAs

public void assertHasSameDimensionsAs(AssertionInfo info,
                                      ELEMENT[][] actual,
                                      Object other)

Assert that the actual array has the same dimensions as the other array.

Parameters:

info - contains information about the assertion.

actual - the given array.

other - the group to compare

Throws:

AssertionError - if the actual group is null.

AssertionError - if the other group is null.

AssertionError - if the actual group does not have the same dimension.

assertNumberOfRows

public void assertNumberOfRows(AssertionInfo info,
                               ELEMENT[][] actual,
                               int expectedNumberOfRows)

Parameters:

info - contains information about the assertion.

actual - the given array.

expectedNumberOfRows - the expected first dimension size of actual.

assertContains

public void assertContains(AssertionInfo info,
