Class StdTemplateProcessor

java.lang.Object
  wt.enterprise.tabularresults.TabularQueryResultsService
      wt.enterprise.tabularresults.StdTemplateProcessor

All Implemented Interfaces:

Externalizable, Serializable, TemplateProcessor

public class StdTemplateProcessor

extends TabularQueryResultsService

implements TemplateProcessor

The class StdTemplateProcessor is an extension of TabularQueryResultsService so that it has access to the table processing functionality of TabularQueryResultsService and extends TemplateProcessor so to be accessable from URLProcessor via a wt.service.properties entry and is able to select a template to process. This class's main purpose is to be able to test the various template processors that build tables. To use this class, you need to place an entry into wt.service.properties that is the name of your query class is a subclass of BasicQueryService. In particular, you have to name your subclass as "queryname"Query where "queryname" should be meaningful relative to the query. At that point you should name your service in wt.service.properties as "queryname" and also name the HTML template that is to be used "queryname".html and place it in codebase\templates\ObjectProperties.

Method Detail

handleRequest

public void handleRequest(HTTPRequest req,
                          HTTPResponse resp)
                   throws WTException

This is a concrete implementation of the TemplateProcessor interface method handleRequest. It will assume that the action being passed is also the name of the HTML template to be used where that HTML template is located in codebase\templates\ObjectProperties

Specified by:

handleRequest in interface TemplateProcessor

Parameters:

req - An HTTPRequest object that holds all of the HTTP information

resp - An HTTPResponse object provides the return output stream

Returns:

void

Throws:

WTException

getContextObj

public Object getContextObj()

Get the contextual object of a TemplateProcessor instance.

Overrides:

Returns:

Object

setContextObj

public void setContextObj(Object context)

Set the value of the contextual object of the TemplateProcessor.

Overrides:

setContextObj in class TabularQueryResultsService

Parameters:
