Class MessagePatternUtil

java.lang.Object

com.ibm.icu.text.MessagePatternUtil

public final class MessagePatternUtil
extends Object

Utilities for working with a MessagePattern. Intended for use in tools when convenience is more important than minimizing runtime and object creations.

This class only has static methods. Each of the nested classes is immutable and thread-safe.

This class and its nested classes are not intended for public subclassing.
