Class Uniquefy

java.lang.Object

com.force.i18n.commons.text.Uniquefy

@Beta
public class Uniquefy
extends Object

Utility to extract unique copies of strings. This is primarily used to reduce the serialized size of an object. Call unique() when constructing the object, so that we use the same java.lang.String object to represent each unique string value. Thus, when serializing the object, instead of repeating the string values, they become references in the serialized representation. Beta class. Classes under com.force.i18n.commons package will be moved into a dedicated project.
