StateState. The status can be any
string, but special meaning is assigned to the static constants in
FlowExecution. The context can be used by implementations to do
whatever they need to do. The same context will be passed to all
State instances, so implementations should be careful that the
context is thread-safe, or used in a thread-safe manner.handle in interface Statehandle in class AbstractStateexecutor - the context passed in by the callerjava.lang.Exception - if anything goes wrongpublic boolean isEndState()
StateState is an end state. Implementations
should return false if processing can continue, even if that would
require a restart.isEndState in interface StateState is the end of processing
