RequestContext (The ZKoss Web Library 10.3.0 API)

All Known Subinterfaces:

DspContext

All Known Implementing Classes:

ExtendletDspContext, ServletDspContext
```
public interface RequestContext
```
The context used to simplify the signatures of XEL function.
It is designed to make the signature of XEL functions (see ServletFns) simpler. For example, ServletFns.getCurrentContext() requires no argument, since it assumes the current context can be retrieved from RequestContexts.getCurrent().

Since:

3.0.0
