Method Summary

Modifier and Type	Method	Description
DoubleArbitrary	between(double min, boolean minIncluded, double max, boolean maxIncluded)	Set the allowed lower min (included) and upper max (included) border of generated numbers.
default DoubleArbitrary	between(double min, double max)	Set the allowed lower min (included) and upper max (included) border of generated numbers.
DoubleArbitrary	greaterOrEqual(double min)	Set the allowed lower min (included) border of generated numbers.
DoubleArbitrary	greaterThan(double min)	Set the allowed lower min (excluded) border of generated numbers.
DoubleArbitrary	lessOrEqual(double max)	Set the allowed upper max (included) border of generated numbers.
DoubleArbitrary	lessThan(double max)	Set the allowed upper max (excluded) border of generated numbers.
DoubleArbitrary	ofScale(int scale)	Set the scale (maximum number of decimal places) to scale.
DoubleArbitrary	shrinkTowards(double target)	Set shrinking target to target which must be between the allowed bounds.
DoubleArbitrary	withSpecialValue(double special)	Inject a special value into generated values and edge cases.
DoubleArbitrary	withStandardSpecialValues()	Inject a selection of special values using withSpecialValue(double): Double.NaN Double.MIN_VALUE Double.MIN_NORMAL Double.POSITIVE_INFINITY Double.NEGATIVE_INFINITY This value can be outside the constraints of the arbitrary, e.g. have more decimals than specified by ofScale(int).

Method Detail

between

default DoubleArbitrary between(double min,
                                double max)

Set the allowed lower min (included) and upper max (included) border of generated numbers.

Parameters:

min - The lower border of possible values

max - The upper border of possible values

Returns:

new instance of arbitrary

between

DoubleArbitrary between(double min,
                        boolean minIncluded,
                        double max,
                        boolean maxIncluded)

Set the allowed lower min (included) and upper max (included) border of generated numbers. Specify if borders should be included in allowed values or not.

Parameters:

min - The lower border of possible values

minIncluded - Should the lower border be included

max - The upper border of possible values

maxIncluded - Should the upper border be included

Returns:

new instance of arbitrary

greaterOrEqual

DoubleArbitrary greaterOrEqual(double min)

Set the allowed lower min (included) border of generated numbers.

Parameters:

min - The lower border of possible values

Returns:

new instance of arbitrary

greaterThan

@API(status=MAINTAINED,
     since="1.2.7")
DoubleArbitrary greaterThan(double min)

Set the allowed lower min (excluded) border of generated numbers.

Parameters:

min - The lower border of possible values

Returns:

new instance of arbitrary

lessOrEqual

DoubleArbitrary lessOrEqual(double max)

Set the allowed upper max (included) border of generated numbers.

Parameters:

max - The upper border of possible values

Returns:

new instance of arbitrary

lessThan

@API(status=MAINTAINED,
     since="1.2.7")
DoubleArbitrary lessThan(double max)

Set the allowed upper max (excluded) border of generated numbers.

Parameters:

max - The upper border of possible values

Returns:

new instance of arbitrary

ofScale

DoubleArbitrary ofScale(int scale)

Set the scale (maximum number of decimal places) to scale.

Parameters:

scale - number of decimal places

Returns:

new instance of arbitrary

shrinkTowards

@API(status=MAINTAINED,
     since="1.4.0")
DoubleArbitrary shrinkTowards(double target)

Set shrinking target to target which must be between the allowed bounds.

Parameters:

target - The value which is considered to be the most simple value for shrinking

Returns:

new instance of arbitrary

withSpecialValue

@API(status=EXPERIMENTAL,
     since="1.5.4")
DoubleArbitrary withSpecialValue(double special)

Inject a special value into generated values and edge cases. This value can be outside the constraints of the arbitrary, e.g. have more decimals than specified by ofScale(int).

Parameters:

special - value

Returns:

new instance of arbitrary

withStandardSpecialValues

@API(status=EXPERIMENTAL,
     since="1.5.4")
DoubleArbitrary withStandardSpecialValues()

Inject a selection of special values using withSpecialValue(double):

• Double.NaN
• Double.MIN_VALUE
• Double.MIN_NORMAL
• Double.POSITIVE_INFINITY
• Double.NEGATIVE_INFINITY

This value can be outside the constraints of the arbitrary, e.g. have more decimals than specified by ofScale(int).

Returns:

new instance of arbitrary
