java.lang.Object org.springframework.scheduling.backportconcurrent.ConcurrentTaskExecutor
public class ConcurrentTaskExecutor
Adapter that takes a JSR-166 backport
edu.emory.mathcs.backport.java.util.concurrent.Executor
and
exposes a Spring TaskExecutor
for it.
NOTE: This class implements Spring's
TaskExecutor
interface as well as
the JSR-166 Executor
interface, with the former being the primary interface, the other just
serving as secondary convenience. For this reason, the exception handling
follows the TaskExecutor contract rather than the Executor contract, in
particular regarding the TaskRejectedException
.
Note that there is a pre-built ThreadPoolTaskExecutor
that allows for
defining a JSR-166 backport
ThreadPoolExecutor
in bean
style, exposing it as a Spring TaskExecutor
directly. This is a convenient alternative to a raw ThreadPoolExecutor
definition with a separate definition of the present adapter class.
