org.eclipse.sapphire.LocalizableText

Represents a string that can be localized by substituting a translated version based on the current locale. Instances of LocalizableText are held as static fields in a class and must be initialized by calling the init method on the class.

The text lookup searches resource files from most specific to most generic, based on the current locale. When looking at the resource files, the key is the field name. If a corresponding resource is not found, the text specified by the @Text annotation is used.

In the following example, two LocalizableText fields are used to implement a simple validator.

 public class Validator { "Value must be specified." )private static LocalizableText mustBeSpecifiedMessage; "Value must not be larger than {0}." )private static LocalizableText mustNotBeLargerThanMessage; static { LocalizableText.init( ExampleValidationService.class ); } public String validate( Integer value, Integer max ) { if( value == null ) { return mustBeSpecifiedMessage.text(); } else if( max != null && value.intValue() > max.intValue() ) { return mustNobeLargerThanMessage.format( max ); } return null; } }

If the locale is set to en_US, the search order will be as follows:

org/eclipse/example/Validator_en_US.properties
org/eclipse/example/Validator_en.properties
org/eclipse/example/Validator.properties
@Text annotation on the field
