                                       Class<?> selfType)

Method Detail

isPresent

public S isPresent()

Verifies that there is a value present in the actual OptionalDouble.

Assertion will pass :

 assertThat(OptionalDouble.of(10.0)).isPresent();

Assertion will fail :

 assertThat(OptionalDouble.empty()).isPresent();

Returns:

this assertion object.

Throws:

AssertionError - if actual value is empty.

AssertionError - if actual is null.

isNotPresent

public S isNotPresent()

Verifies that the actual Optional is empty (alias of isEmpty()).

Assertion will pass :

 assertThat(OptionalDouble.empty()).isNotPresent();

Assertion will fail :

 assertThat(OptionalDouble.of(10.0)).isNotPresent();

Returns:

this assertion object.

isEmpty

public S isEmpty()

Verifies that the actual OptionalDouble is empty.

Assertion will pass :

 assertThat(OptionalDouble.empty()).isEmpty();

Assertion will fail :

 assertThat(OptionalDouble.of(10.0)).isEmpty();

Returns:

this assertion object.

Throws:

AssertionError - if actual value is present.

AssertionError - if actual is null.

isNotEmpty

public S isNotEmpty()

Verifies that there is a value present in the actual OptionalDouble, it's an alias of isPresent().

Assertion will pass :

 assertThat(OptionalDouble.of(10.0)).isNotEmpty();

Assertion will fail :

 assertThat(OptionalDouble.empty()).isNotEmpty();

Returns:

this assertion object.

Throws:

AssertionError - if actual value is empty.

AssertionError - if actual is null.

hasValue

public S hasValue(double expectedValue)

Verifies that the actual OptionalDouble has the value in argument.

Assertion will pass :

 assertThat(OptionalDouble.of(8.0)).hasValue(8.0);
 assertThat(OptionalDouble.of(8.0)).hasValue(Double.valueOf(8.0));
 assertThat(OptionalDouble.of(Double.NaN)).hasValue(Double.NaN); 

Assertion will fail :

 assertThat(OptionalDouble.empty()).hasValue(8.0);
 assertThat(OptionalDouble.of(7)).hasValue(8.0);

Parameters:

expectedValue - the expected value inside the OptionalDouble.

Returns:

this assertion object.

Throws:

AssertionError - if actual value is empty.

AssertionError - if actual is null.

AssertionError - if actual has not the value as expected.

hasValueCloseTo

public S hasValueCloseTo(Double expectedValue,
                         Offset<Double> offset)

Verifies that the actual OptionalDouble has the value close to the argument.

Assertion will pass :

 assertThat(OptionalDouble.of(8)).hasValueCloseTo(8.0, within(0d));
 assertThat(OptionalDouble.of(8)).hasValueCloseTo(8.0, within(1d));
 assertThat(OptionalDouble.of(7)).hasValueCloseTo(8.0, within(1d));

Assertion will fail :

 assertThat(OptionalDouble.empty()).hasValueCloseTo(8.0, within(1d));
 assertThat(OptionalDouble.of(7)).hasValueCloseTo(1.0, within(1d));
 assertThat(OptionalDouble.of(7)).hasValueCloseTo(1.0, null);
 assertThat(OptionalDouble.of(7)).hasValueCloseTo(1.0, within(-1d));

Parameters:

expectedValue - the expected value inside the OptionalDouble.

offset - the given positive offset.

Returns:

this assertion object.

Throws:

AssertionError - if actual value is empty.

AssertionError - if actual is null.

AssertionError - if actual has not the value as expected.

NullPointerException - if offset is null

IllegalArgumentException - if offset is not positive.
