DecisionState
public DecisionState(JobExecutionDecider decider,
String name)
- Parameters:
name
-
handle
public FlowExecutionStatus handle(FlowExecutor executor)
throws Exception
- Description copied from interface:
State
- Handle some business or processing logic and return a status that can be
used to drive a flow to the next
State
. 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.
- Specified by:
handle
in interface State
- Specified by:
handle
in class AbstractState
- Parameters:
executor
- the context passed in by the caller
- Returns:
- a status for the execution
- Throws:
Exception
- if anything goes wrong
isEndState
public boolean isEndState()
- Description copied from interface:
State
- Inquire as to whether a
State
is an end state. Implementations
should return false if processing can continue, even if that would
require a restart.
- Returns:
- true if this
State
is the end of processing
