Method Detail

number

public static org.hamcrest.Matcher<java.lang.Double> number()

Matcher equivalent of the DoubleMath.isNumber(Double). Matches if item is not null and not Double.NaN

finite

public static org.hamcrest.Matcher<java.lang.Double> finite()

Matcher equivalent of the DoubleMath.isFinite(Double). Matches if item is not null, not Double.NaN, and is finite.

zero

public static org.hamcrest.Matcher<java.lang.Number> zero()

Matcher equivalent of the DoubleMath.isZero(Double). Matches if item is not null and equal to 0.0.

positive

public static org.hamcrest.Matcher<java.lang.Number> positive()

Matcher equivalent of the DoubleMath.isPositive(Double). Matches if item is number and greater than 0.0.

negative

public static org.hamcrest.Matcher<java.lang.Number> negative()

Matcher equivalent of the DoubleMath.isNegative(Double). Matches if item is number and lower than 0.0.

equalTo

public static org.hamcrest.Matcher<java.lang.Number> equalTo(java.lang.Number value)

Matcher equivalent of the DoubleMath.equals(Double, Double). Matches if item is double-equal to the specified number value.

greaterThan

public static org.hamcrest.Matcher<java.lang.Number> greaterThan(java.lang.Number value)

Matcher equivalent of the DoubleMath.compare(double, double). Matches if item is not-null, and double-greater than specified number value.

Throws:

java.lang.NullPointerException - if specified value is null

lowerThan

public static org.hamcrest.Matcher<java.lang.Number> lowerThan(java.lang.Number value)

Matcher equivalent of the DoubleMath.compare(double, double). Matches if item is not-null, and double-lower than specified number value.

Throws:

java.lang.NullPointerException - if specified value is null

greaterThanOrEqual

public static org.hamcrest.Matcher<java.lang.Number> greaterThanOrEqual(java.lang.Number value)

Matcher equivalent of the DoubleMath.compare(double, double). Matches if item is not-null, and double-greater than or double-equal to the specified number value.

Throws:

java.lang.NullPointerException - if specified value is null

lowerThanOrEqual

public static org.hamcrest.Matcher<java.lang.Number> lowerThanOrEqual(java.lang.Number value)

Matcher equivalent of the DoubleMath.compare(double, double). Matches if item is not-null, and double-lower than or double-equal to the specified number value.

Throws:

java.lang.NullPointerException - if specified value is null

between

public static org.hamcrest.Matcher<java.lang.Number> between(java.lang.Number min,
                                                             java.lang.Number max)

Matcher equivalent of the DoubleMath.compare(double, double) for two bound arguments. Matches if item is double-greater than first specified number, or double-greater than second specified argument.

Throws:

java.lang.NullPointerException - if either specified value is null

java.lang.IllegalArgumentException - if specified min is greater than specified max

betweenOrEqual

public static org.hamcrest.Matcher<java.lang.Number> betweenOrEqual(java.lang.Number min,
                                                                    java.lang.Number max)

Matcher equivalent of the DoubleMath.compare(double, double) for two bound arguments. Matches if item is double-greater than first specified number, or double-greater than second specified argument, or double-equal to any of them.

Throws:

java.lang.NullPointerException - if either specified value is null

java.lang.IllegalArgumentException - if specified min is greater than specified max
