ThreadLocalRequestScopePropagator

protected ThreadLocalRequestScopePropagator(com.google.inject.Scope scope,
                                            ThreadLocal<C> threadLocal,

Method Detail

wrapImpl

protected final <T> Callable<T> wrapImpl(Callable<T> callable)

Description copied from class: RequestScopePropagator

Ensures that the current request state is available when the passed in Callable is invoked

See RequestScopePropagator.wrap(Callable)

Specified by:

wrapImpl in class RequestScopePropagator

See Also:

RequestScopePropagator.wrap(Callable)

continuingContext

protected abstract C continuingContext(C ctx)

Returns a new context object based on the passed in context that has no request scoped objects initialized.

Note that some code paths expect request-scoped objects like CurrentUser to be constructible starting from just the context object returned by this method. For example, in the SSH scope, the context includes the SshSession, which is used by SshCurrentUserProvider to construct a new CurrentUser in the new thread.

Parameters:

ctx - the context to continue.

Returns:

a new context.
