Configuration

The spirit behind BigIO configuration is default settings that "just work," but control if you need it. The io.bigio.Parameters class provides access to the BigIO configuration structure. It loads any file in the "config" directory of the installation that ends in .properties. It will also put all properties into the System configuration i.e., System.getProperties("your.property") will return a valid result.

// returns the property value if it exists, or null if it does not
Parameters.INSTANCE.getProperty("my.property"); 

// returns the property value if it exists, or "defaultValue" if it does not
Parameters.INSTANCE.getProperty("my.property", "defaultValue");
