Method Summary

Modifier and Type	Method and Description
void	assertIsNaN(AssertionInfo info, NUMBER actual) Verifies that the actual value is equal to NaN. It does not rely on the custom comparisonStrategy (if one is set).
void	assertIsNotNaN(AssertionInfo info, NUMBER actual) Verifies that the actual value is not equal to NaN.
protected abstract boolean	isEqualTo(NUMBER actual, NUMBER expected, Offset<?> offset) Returns true if the two floats parameter are equal within a positive offset, false otherwise. It does not rely on the custom comparisonStrategy (if one is set) because using an offset is already a specific comparison strategy.

Method Detail

assertIsNaN

public void assertIsNaN(AssertionInfo info,
                        NUMBER actual)

Verifies that the actual value is equal to NaN.
It does not rely on the custom comparisonStrategy (if one is set).

Parameters:

info - contains information about the assertion.

actual - the actual value.

Throws:

AssertionError - if the actual value is not equal to NaN.

NaN

protected abstract NUMBER NaN()

assertIsNotNaN

public void assertIsNotNaN(AssertionInfo info,
                           NUMBER actual)

Verifies that the actual value is not equal to NaN.

Parameters:

info - contains information about the assertion.

actual - the actual value.

Throws:

AssertionError - if the actual value is equal to NaN.

isEqualTo

protected abstract boolean isEqualTo(NUMBER actual,
                                     NUMBER expected,
                                     Offset<?> offset)

Returns true if the two floats parameter are equal within a positive offset, false otherwise.
It does not rely on the custom comparisonStrategy (if one is set) because using an offset is already a specific comparison strategy.

Parameters:

actual - the actual value.

expected - the expected value.

offset - the given positive offset.

Returns:

true if the two floats parameter are equal within a positive offset, false otherwise.
