Method Detail

init

Pipeline<?> init(WorkerContext context)
          throws PipelineException

The init method allows implementation to initialize the pipeline. e.g. Initialize their CustomContext here and add it to the WorkerContext through WorkerContext.put(String, CustomContext).

Parameters:

context - the WorkerContext

Returns:

the next pipeline in line

Throws:

PipelineException - can be thrown to indicate that something went wrong.

open

Pipeline<?> open(WorkerContext context,
                 Tag t,
                 ProcessObject po)
          throws PipelineException

Called when an opening tag has been encountered.

Parameters:

context - the WorkerContext

t - the Tag

po - a processObject to put Writables in

Returns:

the next pipeline in line

Throws:

PipelineException - can be thrown to indicate that something went wrong.

content

Pipeline<?> content(WorkerContext context,
                    Tag t,
                    String content,

close

Pipeline<?> close(WorkerContext context,
                  Tag t,
                  ProcessObject po)
           throws PipelineException

Called when a closing tag has been encountered.

Parameters:
