Class StepState
java.lang.Object
org.springframework.batch.core.job.flow.support.state.AbstractState
org.springframework.batch.core.job.flow.support.state.StepState
- All Implemented Interfaces:
- State, StepHolder
public class StepState
- extends AbstractState
- implements StepHolder
State
implementation that delegates to a FlowExecutor
to
execute the specified Step
.
- Since:
- 2.0

StepState
public StepState(Step step)
- Parameters:
step
- the step that will be executed
StepState
public StepState(String name,
Step step)
- Parameters:
name
- for the step that will be executedstep
- the step that will be executed
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
getStep
public Step getStep()
- Specified by:
getStep
in interface StepHolder
- Returns:
- the step
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.
- Specified by:
isEndState
in interface State
- Returns:
- true if this
State
is the end of processing
