class PropertyResourceBundle

java.lang.Object java.util.ResourceBundle java.util.PropertyResourceBundle

Most common way to construct:

InputStream is = …;

PropertyResourceBundle MyBundle = new PropertyResourceBundle(is);

Based on 8 examples

public class PropertyResourceBundle
extends ResourceBundle

PropertyResourceBundle is a concrete subclass of ResourceBundle that manages resources for a locale using a set of static strings from a property file. See {@link ResourceBundle ResourceBundle} for more information about resource bundles.

Unlike other types of resource bundle, you don't subclass PropertyResourceBundle. Instead, you supply properties files containing the resource data. ResourceBundle.getBundle will automatically look for the appropriate properties file and create a PropertyResourceBundle that refers to it. See {@link ResourceBundle#getBundle(java.lang.String, java.util.Locale, java.lang.ClassLoader) ResourceBundle.getBundle} for a complete description of the search and instantiation strategy.

The following example shows a member of a resource bundle family with the base name "MyResources". The text defines the bundle "MyResources_de", the German member of the bundle family. This member is based on PropertyResourceBundle, and the text therefore is the content of the file "MyResources_de.properties" (a related example shows how you can add bundles to this family that are implemented as subclasses of ListResourceBundle). The keys in this example are of the form "s1" etc. The actual keys are entirely up to your choice, so long as they are the same as the keys you use in your program to retrieve the objects from the bundle. Keys are case-sensitive.

 # MessageFormat pattern
 s1=Die Platte \"{1}\" enthält {0}.

 # location of {0} in pattern
 s2=1

 # sample disk name
 s3=Meine Platte

 # first ChoiceFormat choice
 s4=keine Dateien

 # second ChoiceFormat choice
 s5=eine Datei

 # third ChoiceFormat choice
 s6={0,number} Dateien

 # sample date
 s7=3. März 1996
 

Note: PropertyResourceBundle can be constructed either from an InputStream or a Reader, which represents a property file. Constructing a PropertyResourceBundle instance from an InputStream requires that the input stream be encoded in ISO-8859-1. In that case, characters that cannot be represented in ISO-8859-1 encoding must be represented by Unicode Escapes, whereas the other constructor which takes a Reader does not have that limitation.

PropertyResourceBundle

public PropertyResourceBundle(InputStream stream)
                       throws IOException

Creates a property resource bundle from an {@link java.io.InputStream InputStream}. The property file read with this constructor must be encoded in ISO-8859-1.

Parameters:

stream - an InputStream that represents a property file to read from.

Throws:

IOException - if an I/O error occurs

PropertyResourceBundle

public PropertyResourceBundle(Reader reader)
                       throws IOException

Creates a property resource bundle from a {@link java.io.Reader Reader}. Unlike the constructor {@link #PropertyResourceBundle(java.io.InputStream) PropertyResourceBundle(InputStream)}, there is no limitation as to the encoding of the input property file.

Parameters:

reader - a Reader that represents a property file to read from.

Throws:

IOException - if an I/O error occurs

getKeys

public Enumeration getKeys()

Returns an Enumeration of the keys contained in this ResourceBundle and its parent bundles.

Overrides:

getKeys in class ResourceBundle

Returns:

an Enumeration of the keys contained in this ResourceBundle and its parent bundles.

handleGetObject

public Object handleGetObject(String key)

Overrides:

handleGetObject in class ResourceBundle

Parameters:

key

handleKeySet

protected Set handleKeySet()

Returns a Set of the keys contained only in this ResourceBundle.

Overrides:

handleKeySet in class ResourceBundle

Returns:

a Set of the keys contained only in this ResourceBundle
