Method Detail

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 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:

java.lang.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
