Method Detail

perform

public static BaseRewrite.Flow perform(ServletRewrite<?,?> rewrite,
                                       EvaluationContext context,
                                       SubflowTask subflowTask)

Perform the given SubflowTask using the given ServletRewrite event. If modified, the original BaseRewrite.Flow will be restored after task completion.

Parameters:

event - the ServletRewrite event used in the given SubflowTask

Returns:

the resultant BaseRewrite.Flow from the SubflowTask execution.

perform

public static BaseRewrite.Flow perform(ServletRewrite<?,?> event,
                                       EvaluationContext context,
                                       BaseRewrite.Flow subflow,
                                       SubflowTask subflowTask)

Perform the given SubflowTask using the given ServletRewrite event initialized with a new BaseRewrite.Flow. The original BaseRewrite.Flow will be restored after task completion.

Parameters:

event - the ServletRewrite event used in the given SubflowTask

subflow - the BaseRewrite.Flow to be us as the initial state for the given SubflowTask

Returns:

the resultant BaseRewrite.Flow from the SubflowTask execution.

performInSubflow

public abstract void performInSubflow(ServletRewrite<?,?> event,
                                      EvaluationContext context)

The task to be performed in a sub-BaseRewrite.Flow.
