ABSOLUTE
In absolute mode the result of the comparison is true if the value of the second expression, y is within the following range defined by the first value, x.

EXACT
Exact comparing.

RELATIVE
In relative mode, t0 and t1 are treated as percentages and the following range is used instead.

Enum Constant Detail

EXACT

public static final ToleranceMode EXACT

Exact comparing. No tolerances are needed.

ABSOLUTE

public static final ToleranceMode ABSOLUTE

In absolute mode the result of the comparison is true if the value of the second expression, y is within the following range defined by the first value, x.

x - t0, x + t1

RELATIVE

public static final ToleranceMode RELATIVE

In relative mode, t0 and t1 are treated as percentages and the following range is used instead.

x * (1 - t0 / 100), x * (1 + t1 / 100)

Method Detail

values

public static final ToleranceMode[] values()

Returns an array containing the constants of this enum type, in the order they're declared. This method may be used to iterate over the constants as follows:

for(ToleranceMode c : ToleranceMode.values())
        System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they're declared

valueOf

public static ToleranceMode valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

isEqual

public abstract boolean isEqual(double firstNumber,
                                double secondNumber,
                                double tolerance1,
                                double tolerance2,
                                boolean includeLowerBound,
                                boolean includeUpperBound)

Returns true if given numbers are equal; false otherwise.

Parameters:

firstNumber - first number to compare

secondNumber - second number to compare

tolerance1 - tolerance for lower boundary

tolerance2 - tolerance for upper boundary

includeLowerBound - accept lower boundary

includeUpperBound - accept upper boundary

Returns:

true if given numbers are equal; false otherwise

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Enum<ToleranceMode>

parseToleranceMode

public static ToleranceMode parseToleranceMode(java.lang.String toleranceMode)

Parses string representation of ToleranceMode.

Parameters:

toleranceMode - string representation of ToleranceMode

Returns:

parsed ToleranceMode
