All Implemented Interfaces:

IIOMetadataFormat

public abstract class IIOMetadataFormatImpl

extends Object

implements IIOMetadataFormat

A concrete class providing a reusable implementation of the IIOMetadataFormat interface. In addition, a static instance representing the standard, plug-in neutral javax_imageio_1.0 format is provided by the getStandardFormatInstance method.

In order to supply localized descriptions of elements and attributes, a ResourceBundle with a base name of this.getClass().getName() + "Resources" should be supplied via the usual mechanism used by ResourceBundle.getBundle. Briefly, the subclasser supplies one or more additional classes according to a naming convention (by default, the fully-qualified name of the subclass extending IIMetadataFormatImpl, plus the string "Resources", plus the country, language, and variant codes separated by underscores). At run time, calls to getElementDescription or getAttributeDescription will attempt to load such classes dynamically according to the supplied locale, and will use either the element name, or the element name followed by a '/' character followed by the attribute name as a key. This key will be supplied to the ResourceBundle's getString method, and the resulting localized description of the node or attribute is returned.

The subclass may supply a different base name for the resource bundles using the setResourceBaseName method.

A subclass may choose its own localization mechanism, if so desired, by overriding the supplied implementations of getElementDescription and getAttributeDescription.
