Java.util.Resource Bundle.Control.getTimeToLive() Method
Description
The java.util.ResourceBundle.Control.getTimeToLive(String baseName,Locale locale) method Returns the time-to-live (TTL) value for resource bundles that are loaded under this ResourceBundle.Control.
Positive time-to-live values specify the number of milliseconds a bundle can remain in the cache without being validated against the source data from which it was constructed.
The value 0 indicates that a bundle must be validated each time it is retrieved from the cache. TTL_DONT_CACHE specifies that loaded resource bundles are not put in the cache. TTL_NO_EXPIRATION_CONTROL specifies that loaded resource bundles are put in the cache with no expiration control.
Declaration
Following is the declaration for java.util.Control.getTimeToLive() method
public long getTimeToLive(String baseName, Locale locale)
Parameters
baseName − the base name of the resource bundle for which the expiration value is specified.
locale − the locale of the resource bundle for which the expiration value is specified.
Return Value
This method returns the time (0 or a positive millisecond offset from the cached time) to get loaded bundles expired in the cache, TTL_NO_EXPIRATION_CONTROL to disable the expiration control, or TTL_DONT_CACHE to disable caching.
Exception
NullPointerException − if baseName or locale is null
Example
The following example shows the usage of java.util.ResourceBundle.Control.getTimeToLive() method.
package com.tutorialspoint; import java.util.Locale; import java.util.ResourceBundle; import java.util.ResourceBundle.Control; public class ResourceBundleControlDemo { public static void main(String[] args) { // create a new ResourceBundle.Control with default format ResourceBundle.Control rbc = ResourceBundle.Control.getControl(Control.FORMAT_DEFAULT); // print time to live System.out.println("" + rbc.getTimeToLive("hello", Locale.US)); } }
Assuming we have a resource file hello_en_US.properties available in your CLASSPATH, with the following content. This file will be used as an input for our example program −
hello = Hello World!
Let us compile and run the above program, this will produce the following result −
