Class LocalStringsImpl

java.lang.Object

com.sun.enterprise.universal.i18n.LocalStringsImpl

public class LocalStringsImpl
extends Object

This class makes getting localized strings super-simple. This is the companion class to Strings. Use this class when performance may be an issue. I.e. Strings is all-static and creates a ResourceBundle on every call. This class is instantiated once and can be used over and over from the same package.

Specifics:

• Your calling code should have a file named LocalStrings.properties in its package directory.
• If your localized string has no arguments call get(String) to get the localized String value.
• If you have a parameterized string, call get(String, Object...)

Note: You can not get an Exception out of calling this code! If the String or the properties file does not exist, it will return the String that you gave in the first place as the argument.

Example:

• LocalStringsImpl sh = new LocalStringsImpl();
• String s = sh.get("xyz");
• String s = sh.get("xyz", new Date(), 500, "something", 2.00003);
• String s = sh.get("xyz", "something", "foo", "whatever");

Constructor Detail

LocalStringsImpl

public LocalStringsImpl()

Create a LocalStringsImpl instance. Automatically discover the caller's LocalStrings.properties file

LocalStringsImpl

public LocalStringsImpl(Class clazz)

Create a LocalStringsImpl instance. use the proffered class object to find LocalStrings.properties. This is the constructor to use if you are concerned about getting the fastest performance.

LocalStringsImpl

public LocalStringsImpl(String packageName,
                String propsName)

Create a LocalStringsImpl instance. use the proffered String. The String is the FQN of the properties file, without the '.properties'. E.g. 'com.elf.something.LogStrings'
