Method Details

init

public Pipeline<?> init(WorkerContext context)
                 throws PipelineException

Description copied from interface: Pipeline

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).

Specified by:

init in interface Pipeline<MapContext>

Overrides:

init in class AbstractPipeline<MapContext>

Parameters:

context - the WorkerContext

Returns:

the next pipeline in line

Throws:

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

write

private void write(WorkerContext context,
 ProcessObject po)
            throws PipelineException

Parameters:

po -

Throws:

PipelineException

open

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

Description copied from class: AbstractPipeline

Just calls getNext.
Override this to get notified on encountered opening tags.

Specified by:

open in interface Pipeline<MapContext>

Overrides:

open in class AbstractPipeline<MapContext>

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

public Pipeline<?> content(WorkerContext context,
 Tag currentTag,
 String text,
 ProcessObject po)
                    throws PipelineException

Description copied from class: AbstractPipeline

Override this to get notified on encountered content.

Specified by:

content in interface Pipeline<MapContext>

Overrides:

content in class AbstractPipeline<MapContext>

Parameters:

context - the WorkerContext

currentTag - the Tag

text - the content

po - a processObject to put Writables in

Returns:

the next pipeline in line

Throws:
