Package org.apache.commons.daemon.support

Class DaemonConfiguration

java.lang.Object
org.apache.commons.daemon.support.DaemonConfiguration
public final class DaemonConfiguration extends Object
Used by jsvc for Daemon configuration.

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}.
