org.yarnandtail.andhow.property.DblProp

All Implemented Interfaces:

Property<Double>

public class DblProp
extends PropertyBase<Double>

A Property that refers to a Double value. All the basic Java types use a three letter abv. to keep declaration lines short, in the form of: [Type]Prop By default this uses the TrimToNullTrimmer, which removes all whitespace from the value and ultimately null if the value is all whitespace. If a DblProp is configured as a string, such as from a properties file, on command line, environment variable, etc., the value MAY include a trailing 'D' of 'F' (lower case is ok too), as is done with Java literals. This is different than the behavior of LngProp, but is a result of how Java parses these values. E.g., here are several correct ways to spec double value in a properties file: name.of.my.double.property.MY_PROPERTY_1 = 90.00 name.of.my.double.property.MY_PROPERTY_2 = 80.00D name.of.my.double.property.MY_PROPERTY_3 = 70.00F name.of.my.double.property.MY_PROPERTY_4 = 60.00d name.of.my.double.property.MY_PROPERTY_5 = 4
