parseTag

public SGMLTag parseTag(CompilationContext context,
                        PositionReader input,
                        long startPosition,
                        SGMLTag startTag)
                 throws java.io.IOException

Description copied from interface: TagHandler

Parse tag. This method is invoked if a tag with a name this class is registered for is found. The parseTag() method is called before any processing is done. Its purpose is to parse the area this tag spans and probably read in parameters used at execution time.

This method returns the last tag belonging to the area handled by this handler

. For simple one-tag Handlers this is simply the tag passed to this method. If the Handler decides not to handle this tag, this method should return null.

Parameters:

context - The CompilationContext involved

input - The PositionReader, located after the Name token of the Tag

startPosition - The Position parsing of this token began

startTag - the SGMLTag found in the file.

Throws:

java.io.IOException
