 org.wings.template.parser.PageParser
| PageParser | | public class PageParser (Code) | | PageParser
parses SGML markup'd pages and executes
active Tag. Returns its output
through a HttpServletResponse (given in a ParseContext).
Active Tags are handled with SpecialTagHandlers which
can be registered for a specific Tag.
Error handling:
To simplify error detection and correction,
exceptions thrown by the executeTag()-methods of the
pluggable handlers (e.g. called servlets) are printed,
enclosed in comments ("<!-- ... -->"), in the HTML output.

| Method Summary | |
| public void | addTagHandler(String tagname, String handlerClassName)
register a handler for a specific tag (Class name).
Tags are case-insensitive.
Parameters:
tagname - the name of the tag like 'MYSPECIALTAG' or 'SERVLET'
Parameters:
handlerClassName - the name of class implementing theaction for this tag. | | public void | addTagHandler(String tagname, Class handlerClass)
register a handler for a specific tag (Class).
Tags are case-insensitive.
Parameters:
tagname - the name of the tag like 'MYSPECIALTAG' or 'SERVLET'
Parameters:
handlerClass - the class implementing theaction for this tag. | | public static PageParser | getInstance()
returns a singleton instance of this PageParser. | | public Map | getLabels(TemplateSource source)
| | public Iterator | getRegisteredTags()
| | public void | process(TemplateSource source, ParseContext context)
| | public void | process(File file, ParseContext context)
Processes a file. |
| PageParser | | public PageParser()(Code) | | Constructs a new PageParser.
|
| addTagHandler | | public void addTagHandler(String tagname, String handlerClassName) throws ClassNotFoundException(Code) | | register a handler for a specific tag (Class name).
Tags are case-insensitive.
Parameters:
tagname - the name of the tag like 'MYSPECIALTAG' or 'SERVLET'
Parameters:
handlerClassName - the name of class implementing theaction for this tag. This class mustimplement the SpecialTagHandlerinterface.
throws:
ClassNotFoundException - if the class with the specifiedname is not found. |
| addTagHandler | | public void addTagHandler(String tagname, Class handlerClass)(Code) | | register a handler for a specific tag (Class).
Tags are case-insensitive.
Parameters:
tagname - the name of the tag like 'MYSPECIALTAG' or 'SERVLET'
Parameters:
handlerClass - the class implementing theaction for this tag. This class mustimplement the SpecialTagHandlerinterface. |
| getInstance | | public static PageParser getInstance()(Code) | | returns a singleton instance of this PageParser.
You usually want to use the singleton instance to make
use of a central cache.

| process | | public void process(TemplateSource source, ParseContext context) throws IOException(Code) | | Process a general DataStore representing a Template
Parameters:
source - The template TemplateSource
Parameters:
context - The context used while parsing; containsat least the HttpServletRequest andHttpServletResponse.

| process | | public void process(File file, ParseContext context) throws IOException(Code) | | Processes a file.
Parameters:
file - The file containing SGML markup
Parameters:
context - The context used while parsing; containsat least the HttpServletRequest and HttpServletResponse.
