Class StringManager

java.lang.Object
  org.apache.tomcat.util.res.StringManager

public class StringManager
extends Object

An internationalization / localization helper class which reduces the bother of handling ResourceBundles and takes care of the common cases of message formating which otherwise require the creation of Object arrays and such.

The StringManager operates on a package basis. One StringManager per package can be created and accessed via the getManager method call.

The StringManager will look for a ResourceBundle named by the package name given plus the suffix of "LocalStrings". In practice, this means that the localized information will be contained in a LocalStrings.properties file located in the package directory of the classpath.

Please see the documentation for java.util.ResourceBundle for more information.
