org.limewire.setting
Class AbstractNumberSetting<T extends Number & Comparable<T>>

java.lang.Object
  org.limewire.setting.AbstractSetting
      org.limewire.setting.AbstractNumberSetting<T>

All Implemented Interfaces:

Setting

Direct Known Subclasses:

ByteSetting, FloatSetting, IntSetting, LongSetting

public abstract class AbstractNumberSetting<T extends Number & Comparable<T>>
extends AbstractSetting

Provides a Number setting value and ensures any value you set in the future falls within a range. As a subclass of Setting, the setting has a key. If the value is set outside the number range, the value is set to the closer value of either the minimum or maximum range value. For example, if the range is [0,2] and you set the value to 8, the value is actually set to 2.

Additionally, AbstractNumber defines a method for subclasses to convert a string to a Comparable.

Method Detail

setValueInternal

protected void setValueInternal(String value)

Set new property value

Overrides:

setValueInternal in class AbstractSetting

Parameters:

value - new property value

normalizeValue

protected String normalizeValue(String value)

Normalizes a value to an acceptable value for this setting.

convertToComparable

protected abstract Comparable<T> convertToComparable(String value)

Converts a String to a Comparable of the same type as MAX_VALUE and MIN_VALUE.
