Class ConverterTag

Contents
  • All Implemented Interfaces:
    Serializable, IterationTag, JspTag, Tag
    Deprecated. 
    This has been partially replaced by ConverterELTag. The remainder of the functionality, namely, the binding facility and the implementation of the createConverter() method, is now an implementation detail.

    public class ConverterTag
extends TagSupport

    ConverterTag is a base class for all JSP custom actions that create and register a Converter instance on the ValueHolder associated with our most immediate surrounding instance of a tag whose implementation class is a subclass of UIComponentTag. To avoid creating duplicate instances when a page is redisplayed, creation and registration of a Converter occurs only if the corresponding UIComponent was created (by the owning UIComponentTag) during the execution of the current page.

    This class may be used directly to implement a generic converter registration tag (based on the converter-id specified by the converterId attribute), or as a base class for tag instances that support specific Converter subclasses. This converterId attribute must refer to one of the well known converter-ids, or a custom converter-id as defined in a faces-config.xml file.

    Subclasses of this class must implement the createConverter() method, which creates and returns a Converter instance. Any configuration properties that specify behavior of this Converter must have been set by the createConverter() method. Generally, this occurs by copying corresponding attribute values on the tag instance.

    This tag creates no output to the page currently being created. It is used solely for the side effect of Converter creation.
