java.lang.Object
  org.apache.commons.math3.linear.UnmodifiableRealVectorAbstractTest

Direct Known Subclasses:

UnmodifiableArrayRealVectorTest, UnmodifiableOpenMapRealVectorTest

public abstract class UnmodifiableRealVectorAbstractTest
extends Object

This is an abstract test of the unmodifiable vector implementation. These unmodifiable vectors decorate a (modifiable) RealVector; therefore, a new implementation of this abstract test should be considered for each implementation of RealVector.

Version:

$Id$

DIM

protected static final int DIM

The dimension of the randomly generated vectors.

EPS

protected static final double EPS

Absolute tolerance.

EXCLUDE

protected static final Set<String> EXCLUDE

The list of methods which are excluded from the general test testAllButExcluded().

RANDOM

protected static final Random RANDOM

The random number generator (always initialized with the same seed.

public UnmodifiableRealVectorAbstractTest()

equals

public static boolean equals(double x,
                             double y)

Returns true if the specified double are equal (within a given tolerance).

Parameters:

x - First double.

y - Second double.

Returns:

true if x and y are equal.

equals

public static boolean equals(double[] x,
                             double[] y)

Returns true if the specified double arrays are equal (within a given tolerance).

Parameters:

x - First array.

y - Second array.

Returns:

true if x and y are equal.

equals

public static boolean equals(RealVector x,
                             RealVector y)

Returns true if the specified RealVector are equal (within a given tolerance).

Parameters:

x - First vector.

y - Second vector.

Returns:

true if x and y are equal.

equals

public static boolean equals(RealVector x,
                             double[] y)

Returns true if the specified RealVector is equal to the specified double array (within a given tolerance).

Parameters:

x - Vector.

y - Array.

Returns:

true if x and y are equal.

equals

public static boolean equals(RealMatrix x,
                             RealMatrix y)

Returns true if the specified RealMatrix are equal (within a given tolerance).

Parameters:

x - First matrix.

y - Second matrix.

Returns:

true if x and y are equal.

equals

public static boolean equals(Object x,
                             Object y)

Returns true if the specified Object are equal.

Parameters:

x - First object.

y - Second object.

Returns:

true if x and y are equal.

Throws:

IllegalArgumentException - if x and y could not be compared.

createVector

public abstract RealVector createVector()

Creates a new random vector of a specified type. This vector is then to be wrapped in an unmodifiable vector.

Returns:

a new random vector.

createParameter

public Object createParameter(Class<?> c)

Creates a new random object of the specified type.

Parameters:

c - Class of the object to be created.

Returns:

a new random object.

Throws:

IllegalArgumentException - if the specified class is not recognized by this method.

testAllButExcluded

public void testAllButExcluded()
                        throws IllegalAccessException,
                               IllegalArgumentException,
                               InvocationTargetException

This test calls callMethod(Method, RealVector, Object...) on every method defined in interface RealVector. It generates the appropriate random arguments. Some methods are manually excluded (see EXCLUDE), they must be handled by separate tests.

Throws:

IllegalAccessException

IllegalArgumentException

InvocationTargetException
