Examples of org.zkoss.web.servlet.xel.RequestContext

org.zkoss.web.servlet.xel.RequestContext
The context used to simplify the signatures of XEL function.
It is designed to make the signature of XEL functions (see {@link org.zkoss.web.fn.ServletFns}) simpler. For example, {@link org.zkoss.web.fn.ServletFns#isExplorer} requiresno argument, since it assumes the current context can be retrieved from {@link RequestContexts#getCurrent}. @author tomyeh @since 3.0.0

  public Object resolveVariable(String name) throws XelException {
    final Object o = Labels.getLabel(name);
    if (o != null)
      return o;


    final RequestContext jc = RequestContexts.getCurrent();
    if (jc != null) {
      final VariableResolver parent = jc.getVariableResolver();
      if (parent != null)
        return parent.resolveVariable(name);
    }
    return null;
