Method Detail

renewCurrentSessionScope

@Nonnull
public static com.helger.commons.state.EChange renewCurrentSessionScope(boolean bInvalidateHttpSession)

Renew the current session scope. This means all session and session application scopes are cleared, and only attributes implementing the IScopeRenewalAware interface are kept.

Parameters:

bInvalidateHttpSession - if true the underlying HTTP session is also invalidated and a new session is created.

Returns:

EChange.UNCHANGED if no session scope is present.

renewSessionScope

@Nullable
public static ISessionWebScope renewSessionScope(@Nonnull
                                                            javax.servlet.http.HttpSession aHttpSession)

Renew the session scope identified by the passed HTTP session. Note: the underlying HTTP session is not invalidate, because we have no way to retrieve a new underlying HTTP session, because no request is present.

Parameters:

aHttpSession - The HTTP session to be renewed.

Returns:

null if nothing was changed, the new session web scope otherwise.
