Class MessageFormatFactory

java.lang.Object
com.aoapps.lang.text.MessageFormatFactory
public final class MessageFormatFactory extends Object
Creates MessageFormat objects and caches them. This may be used as an alternative to the MessageFormat constructor to increase performance.

The following are the results of a single-threaded benchmark with a simple two-value substitution: 

 Comparing constructor/factory and format together:
     Constructor: 1148.127153
     Factory....: 283.366235
     4 times improvement

 Comparing constructor/factory only:
     Constructor: 985.182660
     Factory....: 42.602040
     23 times improvement

Longer or more complicated patterns should benefit even more (this assertion not tested).
