isDeepEqualToback to summary
public Byte2DArrayAssert isDeepEqualTo(byte[][] expected)

Implements abstract org.assertj.core.api.Abstract2DArrayAssert.isDeepEqualTo.

Verifies that the actual byte[][] is deeply equal to the given one.

Two arrays are considered deeply equal if both are null or if they refer to arrays that contain the same number of elements and all corresponding pairs of elements in the two arrays are deeply equal.

Example:

 // assertion will pass
assertThat(new byte[][] {{1, 2}, {3, 4}}).isDeepEqualTo(new byte[][] {{1, 2}, {3, 4}});

// assertions will fail
assertThat(new byte[][] {{1, 2}, {3, 4}}).isDeepEqualTo(new byte[][] {{1, 2}, {9, 10}});
assertThat(new byte[][] {{1, 2}, {3, 4}}).isDeepEqualTo(new byte[][] {{1, 2, 3}, {4}});
Parameters
expected:byte[][]

the given value to compare the actual value to.

Returns:Byte2DArrayAssert

this assertion object.

Annotations
@Override
Exceptions
AssertionError:
if the actual value is not deeply equal to the given one.
isEmptyback to summary
public void isEmpty()

Implements org.assertj.core.api.Array2DAssert.isEmpty.

Verifies that the actual byte[][] is empty, empty means the array has no elements, said otherwise it can have any number of rows but all rows must be empty.

Example:

 // assertions will pass
assertThat(new byte[][] {{}}).isEmpty();
// this is considered empty as there are no elements in the 2d array which is comprised of 3 empty rows.
assertThat(new byte[][] {{ }, { }, { }}).isEmpty();

// assertions will fail
assertThat(new byte[][] {{ 1 }, { 2 }}).isEmpty();
byte[][] array = null;
assertThat(array).isEmpty();
Annotations
@Override
Exceptions
AssertionError:
if the actual byte[][] is not empty.
isEqualToback to summary
public Byte2DArrayAssert isEqualTo(Object expected)

Overrides org.assertj.core.api.AbstractAssert.isEqualTo.

Implements org.assertj.core.api.Assert.isEqualTo.

Verifies that the actual byte[][] is equal to the given one.

Warning

This method will use equals to compare (it will compare arrays references only).
Unless you specify a comparator with usingComparator(Comparator), it is advised to use isDeepEqualTo(byte[][]) instead.

Example:

 byte[][] array = {{1, 2}, {3, 4}};

// assertion will pass
assertThat(array).isEqualTo(array);

// assertion will fail as isEqualTo calls equals which compares arrays references only.
assertThat(array).isEqualTo(new byte[][] {{1, 2}, {3, 4}});
Parameters
expected:Object

the given value to compare the actual byte[][] to.

Returns:Byte2DArrayAssert

this assertion object.

Annotations
@Override
Exceptions
AssertionError:
if the actual byte[][] is not equal to the given one.
isNotEmptyback to summary
public Byte2DArrayAssert isNotEmpty()

Implements org.assertj.core.api.Array2DAssert.isNotEmpty.

Verifies that the actual byte[][] is not empty, not empty means the array has at least one element.

Example:

 // assertions will pass
assertThat(new byte[][] {{ 1 }, { 2 }}).isNotEmpty();
assertThat(new byte[][] {{ }, { 2 }}).isNotEmpty();

// assertions will fail
assertThat(new byte[][] { }).isNotEmpty();
assertThat(new byte[][] {{ }}).isNotEmpty();
// this is considered empty as there are no elements in the 2d array which is comprised of 3 empty rows.
assertThat(new byte[][] {{ }, { }, { }}).isNotEmpty();
byte[][] array = null;
assertThat(array).isNotEmpty();
Returns:Byte2DArrayAssert

this assertion object.

Annotations
@Override

isNullOrEmptyback to summary
public void isNullOrEmpty()

Implements org.assertj.core.api.Array2DAssert.isNullOrEmpty.

Verifies that the actual byte[][] is null or empty, empty means the array has no elements, said otherwise it can have any number of rows but all rows must be empty.

Example:

 // assertions will pass
byte[][] array = null;
assertThat(array).isNullOrEmpty();
assertThat(new byte[][] { }).isNullOrEmpty();
assertThat(new byte[][] {{ }}).isNullOrEmpty();
// this is considered empty as there are no elements in the 2d array which is comprised of 3 empty rows.
