    • isDeepEqualTo

      public Float2DArrayAssert isDeepEqualTo(float[][] expected)
      Verifies that the actual float[][] 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 float[][] {{1.0f, 2.0f}, {3.0f, 4.0f}}).isDeepEqualTo(new float[][] {{1.0f, 2.0f}, {3.0f, 4.0f}});

 // assertions will fail
 assertThat(new float[][] {{1.0f, 2.0f}, {3.0f, 4.0f}}).isDeepEqualTo(new float[][] {{1.0f, 2.0f}, {9.0f, 10.0f}});
 assertThat(new float[][] {{1.0f, 2.0f}, {3.0f, 4.0f}}).isDeepEqualTo(new float[][] {{1.0f, 2.0f, 3.0f}, {4.0f}});
      Specified by:
      isDeepEqualTo in class Abstract2DArrayAssert<Float2DArrayAssert,float[][],Float>
      Parameters:
      expected - the given value to compare the actual value to.
      Returns:
      this assertion object.
      Throws:
      AssertionError - if the actual value is not deeply equal to the given one.

    • isEqualTo

      public Float2DArrayAssert isEqualTo(Object expected)
      Verifies that the actual float[][] 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 AbstractAssert.usingComparator(Comparator), it is advised to use isDeepEqualTo(float[][]) instead.

      Example: 

       float[][] array = {{1.0f, 2.0f}, {3.0f, 4.0f}};

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

 // assertion will fail as isEqualTo calls equals which compares arrays references only.
 assertThat(array).isEqualTo(new float[][] {{1.0f, 2.0f}, {3.0f, 4.0f}});
      Specified by:
      isEqualTo in interface Assert<Float2DArrayAssert,float[][]>
      Overrides:
      isEqualTo in class AbstractAssert<Float2DArrayAssert,float[][]>
      Parameters:
      expected - the given value to compare the actual float[][] to.
      Returns:
      this assertion object.
      Throws:
      AssertionError - if the actual float[][] is not equal to the given one.

    • isNullOrEmpty

      public void isNullOrEmpty()
      Verifies that the actual float[][] 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
 float[][] array = null;
 assertThat(array).isNullOrEmpty();
 assertThat(new float[][] { }).isNullOrEmpty();
 assertThat(new float[][] {{ }}).isNullOrEmpty();
 // this is considered empty as there are no elements in the 2d array which is comprised of 3 empty rows.
 assertThat(new float[][] {{ }, { }, { }}).isNullOrEmpty();

 // assertion will fail
 assertThat(new float[][] {{ 1.0 }, { 2.0 }}).isNullOrEmpty();
      Throws:
      AssertionError - if the actual float[][] is not null or not empty.

    • isEmpty

      public void isEmpty()
      Verifies that the actual float[][] 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 float[][] {{}}).isEmpty();
 // this is considered empty as there are no elements in the 2d array which is comprised of 3 empty rows.
 assertThat(new float[][] {{ }, { }, { }}).isEmpty();

 // assertions will fail
 assertThat(new float[][] {{ 1.0 }, { 2.0 }}).isEmpty();
 float[][] array = null;
 assertThat(array).isEmpty();
      Throws:
      AssertionError - if the actual float[][] is not empty.

    • isNotEmpty

      public Float2DArrayAssert isNotEmpty()
      Verifies that the actual float[][] is not empty, not empty means the array has at least one element.

      Example: 

       // assertions will pass
 assertThat(new float[][] {{ 1.0 }, { 2.0 }}).isNotEmpty();
 assertThat(new float[][] {{ }, { 2.0 }}).isNotEmpty();

 // assertions will fail
 assertThat(new float[][] { }).isNotEmpty();
 assertThat(new float[][] {{ }}).isNotEmpty();
 // this is considered empty as there are no elements in the 2d array which is comprised of 3 empty rows.
 assertThat(new float[][] {{ }, { }, { }}).isNotEmpty();
 float[][] array = null;
 assertThat(array).isNotEmpty();
      Returns:
      this assertion object.
      Throws:
      AssertionError - if the actual float[][] is empty or null.

    • hasDimensions

 assertThat(new float[][] {{1.0f, 2.0f, 3.0f}, {4.0f, 5.0f, 6.0f, 7.0f}}).hasDimensions(2, 3);
      Parameters:
      expectedFirstDimension - the expected number of values in first dimension of the actual float[][].
      expectedSecondDimension - the expected number of values in second dimension of the actual float[][].
      Returns:
      this assertion object.
      Throws:
