Class Vector4EqualityComparer

Use this class to compare two Vector4 objects for equality with NUnit constraints. Call Vector4EqualityComparer.Instance to perform comparisons using default calculation error value 0.0001f. To set a custom test value, instantiate a new comparer using the one argument constructor.

Constructors

Vector4EqualityComparer(float)

Initializes an instance of Vector4Equality comparer with custom allowed calculation error.

Declaration
public Vector4EqualityComparer(float allowedError)
Parameters
Type Name Description
float allowedError

This value identifies the calculation error allowed.

Properties

Instance

A comparer instance with the default calculation error value set to 0.0001f.

Declaration
public static Vector4EqualityComparer Instance { get; }
Property Value
Type Description
Vector4EqualityComparer

Methods

Equals(Vector4, Vector4)

Compares the actual and expected Vector4 objects for equality using AreFloatsEqual(float, float, float) to compare the x, y, z, and w attributes of Vector4.

Declaration
public bool Equals(Vector4 expected, Vector4 actual)
Parameters
Type Name Description
Vector4 expected

The expected Vector4 used for comparison
Vector4 actual

The actual Vector4 to test
Returns
Type Description
bool

True if the vectors are equals, false otherwise.
Examples
[TestFixture]
 public class Vector4Test
 {
     [Test]
     public void VerifyThat_TwoVector4ObjectsAreEqual()
     {
         // Custom error 10e-6f
         var actual = new Vector4(0, 0, 1e-6f, 1e-6f);
         var expected = new Vector4(1e-6f, 0f, 0f, 0f);
         var comparer = new Vector4EqualityComparer(10e-6f);

         Assert.That(actual, Is.EqualTo(expected).Using(comparer));

         // Default error 0.0001f
         actual = new Vector4(0.01f, 0.01f, 0f, 0f);
         expected = new Vector4(0.01f, 0.01f, 0f, 0f);

         Assert.That(actual, Is.EqualTo(expected).Using(Vector4EqualityComparer.Instance));
     }
 }

GetHashCode(Vector4)

Serves as the default hash function.

Declaration
public int GetHashCode(Vector4 vec4)
Parameters
Type Name Description
Vector4 vec4

A not null Vector4 object
Returns
Type Description
int

Returns 0
