Interface IEngine

All Superinterfaces:

WebRequestServicer

All Known Implementing Classes:

AbstractEngine, BaseEngine, WMLEngine

public interface IEngine
extends WebRequestServicer

Defines the core, session-persistant object used to run a Tapestry application for a single client (each client will have its own instance of the engine).

The engine exists to provide core services to the pages and components that make up the application. The engine is a delegate to the ApplicationServlet.

Starting in release 4.0, the engine is kept around only for compatibility (with release 3.0). It's functions have been moved over into a collection of HiveMind services (or are in the process of doing so).

Method Detail

getLocale

Locale getLocale()

Returns the locale for the engine. This locale is used when selecting templates and assets.

setLocale

void setLocale(Locale value)

getOutputEncoding

String getOutputEncoding()

Returns the encoding to be used to generate the responses and accept the requests.

3.0
