public final class DaemonConfiguration extends Object
Configuration is read from properties file.
If no properties file is given the daemon.properties
is used from the current directory.
The properties file can have property values expanded at runtime
by using System properties or execution environment. The part
of the property value between ${} and {@code }
will be used as System property or environment key. If found then
the entire ${foo}
will be replaced by the value of
either system property or environment variable named foo
.
If no variable is found the ${foo}
will be passed as is.
In case of $${foo}
this will be unescaped and resulting
value will be ${foo}
.
