com.itextpdf.tool.xml.html.DefaultTagProcessorFactory

All Implemented Interfaces:

TagProcessorFactory

public class DefaultTagProcessorFactory
extends java.lang.Object
implements TagProcessorFactory

A Default implementation of the TagProcessorFactory that uses a map to store the TagProcessors. Within the same ClassLoaders this Processor can also load the processors when they are only stored with there fully qualified class names.
Note: this implementation does not use namespaces (yet)!
