| SpecialTagHandler | | public interface SpecialTagHandler (Code) | | |
| Method Summary | |
| void | executeTag(ParseContext context, InputStream input)
actually perform the action associated with this tag.
throws:
Exception - anything can happen .. | | long | getTagLength()
Get the length of the area in the sourcefile. | | long | getTagStart()
Get start position of the area in the sourcefile this
handler processes. | | SGMLTag | parseTag(ParseContext context, PositionReader input, long startPos, SGMLTag startTag)
Parse tag.
This method is invoked if a tag with a name
this class is registered for is found.
It gets the ServletConfiguration of the PageParser
servet and a PositionReader, placed after name of
the current tag.
The parseTag() method is called before
any processing is done. |
| executeTag | | void executeTag(ParseContext context, InputStream input) throws Exception(Code) | | actually perform the action associated with this tag.
throws:
Exception - anything can happen .. and throw an Exceptionwhich is caught in PageParser |
| getTagLength | | long getTagLength()(Code) | | Get the length of the area in the sourcefile.
The area this handler processes is skipped in the inputfile.
Usually this represents the length of the single
<SpecialTag> or the
area <SpecialTag>...</SpecialTag>
|
| getTagStart | | long getTagStart()(Code) | | Get start position of the area in the sourcefile this
handler processes.
This is usually the position of the "<"
of the <SpecialTag> within the inputfile.
|
| parseTag | | SGMLTag parseTag(ParseContext context, PositionReader input, long startPos, SGMLTag startTag) throws IOException(Code) | | Parse tag.
This method is invoked if a tag with a name
this class is registered for is found.
It gets the ServletConfiguration of the PageParser
servet and a PositionReader, placed after name of
the current tag.
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 server side included
servlets, this would be </SERVLET>).
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 context used while parsing; containsat least the HttpServletRequest and HttpServletResponse.
Parameters:
input - The PositionReader, located after the Name tokenof the Tag
Parameters:
startPos - The Position parsing of this token began
Parameters:
startTag - the SGMLTag found in the file. |
