   A string based interface to configure package components.

public interface OptionHandler {

     Activate the options that were previously set with calls to option


This allows to defer activiation of the options until all options have been set. This is required for components which have related options that remain ambigous until all are set.

For example, the FileAppender has the {@link org.apache.log4j.FileAppender#setFile File} and {@link org.apache.log4j.FileAppender#setAppend Append} options both of which are ambigous until the other is also set. */ void activateOptions(); /** Return list of strings that the OptionHandler instance recognizes. @deprecated We now use JavaBeans style getters/setters. */ // String[] getOptionStrings(); /** Set option to value.

The handling of each option depends on the OptionHandler instance. Some options may become active immediately whereas other may be activated only when {@link #activateOptions} is called. @deprecated We now use JavaBeans style getters/setters. */ //void setOption(String option, String value); }
