Constructor Detail

NumberPolicy.ValueVariable

public NumberPolicy.ValueVariable(double min,
                                  double max)

Method Detail

min

public double min()

Description copied from class: NumberPolicy

The lowest possible value under the policy.

Set immutably during construction but only accessed via this method, enabling subclasses to define it dynamically by overriding.

Overrides:

min in class NumberPolicy

max

public double max()

Description copied from class: NumberPolicy

The highest possible value under the policy.

Set immutably during construction but only accessed via this method, enabling subclasses to define it dynamically by overriding.

Overrides:

max in class NumberPolicy

format

public int format()

Description copied from class: NumberPolicy

Hint on formatting the number.

These are defined by the class FORMAT_x constants, which are mutually exclusive.

For FORMAT_PLACES_x constants the format should normally be consistent with unit.

Overrides:

format in class NumberPolicy

unit

public final double unit()

Description copied from class: NumberPolicy

The smallest possible increment under the policy.

The default implementation deduces this value from NumberPolicy.format().

Overrides:

unit in class NumberPolicy

currentValue

protected abstract double currentValue()

toString

public java.lang.String toString()

Overrides:

toString in class NumberPolicy.Ticked
