Method Detail
getState
public State getState()
isEndState
public boolean isEndState()
Description copied from interface:State
Inquire as to whether aState
is an end state. Implementations should return false if processing can continue, even if that would require a restart.- Specified by:
isEndState
in interfaceState
- Returns:
- true if this
State
is the end of processing
handle
public FlowExecutionStatus handle(FlowExecutor executor) throws java.lang.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 nextState
. The status can be any string, but special meaning is assigned to the static constants inFlowExecution
. The context can be used by implementations to do whatever they need to do. The same context will be passed to allState
instances, so implementations should be careful that the context is thread-safe, or used in a thread-safe manner.- Specified by:
handle
in interfaceState
- Specified by:

in classAbstractState
- Parameters:
executor
- the context passed in by the caller- Returns:
- a status for the execution
- Throws:
java.lang.Exception
- if anything goes wrong
