Examples of org.apache.commons.chain.config.ConfigParser

org.apache.commons.chain.config.ConfigParser

Class to parse the contents of an XML configuration file (using Commons Digester) that defines and configures commands and command chains to be registered in a {@link Catalog}. Advanced users can configure the detailed parsing behavior by configuring the properties of an instance of this class prior to calling the parse() method. It is legal to call the parse() method more than once, in order to parse more than one configuration document.
