Annotation Type Messages.AlternateMessage

@Retention(value=RUNTIME)
 @Target(value=METHOD)
 @Documented
public static @interface Messages.AlternateMessage

Provides alternate forms of a message, such as are needed when plural forms are used or a placeholder has known gender. The selection of which form to use is based on the value of the arguments marked PluralCount and/or Select.

Example:

   @DefaultMessage("You have {0} widgets.")
   @AlternateMessage({"one", "You have one widget.")
   String example(@PluralCount int count);
 

If multiple Messages.PluralCount or Messages.Select parameters are supplied, the forms for each, in the order they appear in the parameter list, are supplied separated by a vertical bar ("|"). Example:

   @DefaultMessage("You have {0} messages and {1} notifications.")
   @AlternateMessage({
       "=0|=0", "You have no messages or notifications."
       "=0|one", "You have a notification."
       "one|=0", "You have a message."
       "one|one", "You have one message and one notification."
       "other|one", "You have {0} messages and one notification."
       "one|other", "You have one message and {1} notifications."
   })
   String messages(@PluralCount int msgCount,
       @PluralCount int notifyCount);
 

Note that the number of permutations can grow quickly, and that the default message is used when every Messages.PluralCount or Messages.Select would use the "other" value.

Element Detail

value

public abstract java.lang.String[] value

An array of pairs of strings containing the strings for different forms. Each pair is the name of a form followed by the string in the source locale for that form. Each form name is the name of a plural form if Messages.PluralCount is used, or the matching value if Messages.Select is used. An example for a locale that has "none", "one", and "other" plural forms:

 @DefaultMessage("{0} widgets")
 @AlternateMessage({"none", "No widgets", "one", "One widget"})
 

Note that the plural form "other" gets the translation specified in @DefaultMessage, as does any @Select value not listed. If more than one way of selecting a translation exists, they will be combined, separated with |, in the order they are supplied as arguments in the method. For example:

   @DefaultMessage("{0} gave away their {2} widgets")
   @AlternateMesssage({
     "MALE|other", "{0} gave away his {2} widgets",
     "FEMALE|other", "{0} gave away her {2} widgets",
     "MALE|one", "{0} gave away his widget",
     "FEMALE|one", "{0} gave away her widget",
     "other|one", "{0} gave away their widget",
   })
   String giveAway(String name, @Select Gender gender,
       @PluralCount int count);
