Interface TagHandler

All Superinterfaces:

TagHandlerBase

All Known Implementing Classes:

DefaultTagHandler

public interface TagHandler
extends TagHandlerBase

Defines minimal requirements for a TagHandler.

A TagHandler is called for the start and the end of a tag in the data being processed. Besides the methods listed, a TagHandler can choose to implement additional methods via which it will receive simple and complex parameters, as well as indicating that some parameters are required. For more details about that see TagDispatcher

TagHandler classes are created using the default constructor, which must therefor be present in any implementing class.

TagHandler instances are not re-used and are created for each occurrence of a tag in the TCDL content. Also, when the handler is registered internally from (internal or external) configuration an instance is created to verify that the class can be found and created. If this instance is implements the TagMetaEventListener interface it will be stored and used to pass on the events defined in this interface.
