public class YamlConfiguration
extends org.apache.commons.configuration2.BaseHierarchicalConfiguration
implements org.apache.commons.configuration2.FileBasedConfiguration, org.apache.commons.configuration2.io.InputStreamSupport

Implementation of Apache Commons HierarchicalConfiguration that parses a YAML configuration file and loads the configuration in memory for easy access.

Example configuration file:

 server:
      hostname: localhost
      port: 8080
 mimeTypes:
      - application/pdf
      - application/msword
 

How to read and access the configuration

 YamlConfiguration config = new YamlConfiguration();
 config.read(new FileReader("config.yaml"));

 String serverHostname = config.getString("server.hostname");
 String serverPort = config.getInt("server.port");
 String pdfMimeType = config.getString("mimeTypes(0)");
 String mswordMimeType = config.getString("mimeTypes(1)");
