dataArray, dataLocation

Constructor Summary

HTTPRequestDataMapper()
Allow the default constructor, but please use a parameterized constructor!

HTTPRequestDataMapper(AbstractProcessor processor)
Constructs a new data mapper which references back to the DataLocation who created it.

Method Summary

void	close() Close the data mapper so it can clean up any resources it may have allocated.
void	commitWrites() Nothing to do here, not a data sink.
protected boolean	constructDataArrayFromHttpRequest(java.lang.String httpObjectName) Helper method to construct a DataArray from the HTTP input form.
protected DataMappedObject	constructObjectFromDataArray(java.lang.String dataMappedObjectClass) Helper method to map an individual object from an HTTP input form to a DataMappedObject.
java.util.Vector	findBySearchCriteria(DataMappedObject dmo, java.lang.String criteriaKey) Nothing to do here, search criteria is kind of meaningless for a simple HTTP get/post
javax.servlet.http.HttpServletRequest	getRequest() Returns the HTTP Request object.
javax.servlet.http.HttpServletResponse	getResponse() Returns the HTTP Response object.
protected javax.servlet.http.HttpSession	getSession() Retrieves (or creates if not yet created) the user's session info.
protected void	mapObject(java.lang.String httpObject, java.lang.String dataMappedObjectClass) Helper method to map an individual object from an HTTP input form to a DataMappedObject.
void	mapObjects() Maps all objects from the Processor into request or session objects.
void	write(DataMappedObject dmo, Relationship relationship) Nothing to do here, not a data sink.
