org.pentaho.reporting.libraries.formatting.FastMessageFormat
A wrapper around the java.text.MessageFormat class. This wrapper limits the possible interactions with the wrapped format class and therefore eliminates the need to clone the choice format whenever the wrapper is cloned.
The pattern accepted by the this class is the same as the message-format pattern, with the exception that this class allows to escape the special characters using the backslash-character. Unlike the original MessageFormat class, this class allows to set a null-string for parameters that are null. @author Thomas Morgner
