public abstract class ConverterELTag extends TagSupport
ConverterELTag is a base class for all Jakarta Server Pages custom actions that create and register
Converter instance on the
ValueHolder associated with our most immediate surrounding instance
of a tag whose implementation class is a subclass of
UIComponentClassicTagBase. 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 as a base class for tag instances that support specific
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

public int doStartTag() throws JspException
Create a new instance of the specified
Converter class, and register it with the
associated with our most immediately surrounding
UIComponentClassicTagBase instance, if the
UIComponent instance was created by this execution of the containing Jakarta Server Pages page. If the
localValue of the
UIComponent is a String, attempt to convert it.
