public final class FacesLocal extends Object
Collection of utility methods for the JSF API that are mainly shortcuts for obtaining stuff from the provided
FacesContext
argument. In effect, it 'flattens' the hierarchy of nested objects.
The difference with Faces
is that no one method of FacesLocal
obtains the FacesContext
from
the current thread by FacesContext.getCurrentInstance()
. This job is up to the caller. This is more efficient
in situations where multiple utility methods needs to be called at the same time. Invoking
FacesContext.getCurrentInstance()
is at its own an extremely cheap operation, however as it's to be obtained
as a ThreadLocal
variable, it's during the call still blocking all other running threads for some nanoseconds
or so.
Note that methods which are directly available on FacesContext
instance itself, such as
FacesContext.getExternalContext()
, FacesContext.getViewRoot()
,
FacesContext.isValidationFailed()
, etc are not delegated by the this utility class, because it would design
technically not make any sense to delegate a single-depth method call like follows:
ExternalContext externalContext = FacesLocal.getExternalContext(facesContext);
instead of just calling it directly like follows:
ExternalContext externalContext = facesContext.getExternalContext();
Some examples (for the full list, check the API documentation):
FacesContext context = Faces.getContext(); User user = FacesLocal.getSessionAttribute(context, "user"); Item item = FacesLocal.evaluateExpressionGet(context, "#{item}"); String cookieValue = FacesLocal.getRequestCookie(context, "cookieName"); List<Locale> supportedLocales = FacesLocal.getSupportedLocales(context); FacesLocal.invalidateSession(context); FacesLocal.redirect(context, "login.xhtml");
