- All Implemented Interfaces:
- java.lang.Cloneable, java.util.Map, java.io.Serializable
- public final class DoubleProperties
- extends java.util.Properties
A properties object that links two independent
properties together. The read property set is always
searched first, with the write property set being
second. But any put() calls are always made directly to
the write object.
Only the put(), keys() and getProperty() methods are supported
by this class.
