public abstract class OracleResourceBundle

extends java.util.ResourceBundle

OracleResourceBundle is a abstract subclass of ResourceBundle that manages locale-dependent resources in an array. By using numeric references rather than string references, it requires less overhead and provides better performance than PropertyResourceBundle and ListResourceBundle. See ResourceBundle for more information about resource bundles in general.

Subclasses must override getContents and provide an array, where each item in the array is the resource value. The key for each resource value is its numeric offset in the array. For example, the first element in the array has the key 0. It may be retrieved by using either getObject(0) or getObject("0");

Unlike ListResourceBundle and PropertyResourceBundle, where each locale-specific variation of a bundle can override only selected resources, with OracleResourceBundle, each variation must provide the complete set of Resources. For example,if MyResources has three resources, then MyResources_ja and MyResources_fr must also have three resources.

The following example shows the structure of a ResourceBundle based on OracleResourceBundle.

 class MyResource extends OracleResourceBundle {
 	public Object[] getContents() {
 		return contents;
 	}
 	static final Object[] contents = {
 	// LOCALIZE THIS
 		"Yes",    // Label for the YES button
 		"No",     // Label for the NO button
 		"Cancel"  // Label for the CANCEL button
 	// END OF MATERIAL TO LOCALIZE
 	};
 }
