Class ConfigParserImpl

java.lang.Object
  org.kuali.rice.core.config.ConfigParserImpl

All Implemented Interfaces:

ConfigParser

public class ConfigParserImpl
extends Object
implements ConfigParser

ConfigParser implementation that supports a hierarchy of configs, in which configs can include other configs. Variable tokens are resolved at parse time, in the order in which they are encountered. This class relies on Spring for resource loading and Apache Commons Lang for variable replacement.
