Method Detail

supports

public boolean supports(Job pJob)

Description copied from interface: DataProcessor

Returns true if this processor supports the given type of job.

Specified by:

supports in interface DataProcessor

Specified by:

supports in class AbstractDataProcessor

Returns:

init

public void init()
          throws ProcessingException

Description copied from interface: DataProcessor

Initializes the data processor. (Create buffers, open file handles etc.)

Specified by:

init in interface DataProcessor

Overrides:

init in class AbstractDataProcessor

Throws:

ProcessingException

finish

public void finish()

Description copied from interface: DataProcessor

Shutdown the data processor. (Release buffers, file handles etc.)

Specified by:

finish in interface DataProcessor

Overrides:

finish in class AbstractDataProcessor

process

public DataChunk process(DataChunk pDataChunk)

Description copied from interface: DataProcessor

Processes the given data chunk.

Specified by:

process in interface DataProcessor

Returns:

The pDataChunk pointer or a new pointer to changed data.

loadPatterns

protected java.util.regex.Pattern[] loadPatterns(java.lang.String propertyName)

extractURLs

public java.net.URI[] extractURLs(java.lang.CharSequence pData)

setApplicationContext

public void setApplicationContext(org.springframework.context.ApplicationContext pContext)
                           throws org.springframework.beans.BeansException

Specified by:

setApplicationContext in interface org.springframework.context.ApplicationContextAware

Throws:

org.springframework.beans.BeansException

needsDataAsWholeChunk

public boolean needsDataAsWholeChunk()

Description copied from interface: DataProcessor

Asks the processor if it needs the data from the data retriever in one chunk and not in multiple pieces.

Specified by:

needsDataAsWholeChunk in interface DataProcessor

Returns:

isConsumer

public boolean isConsumer()

Description copied from interface: DataProcessor

'Consumes' (saves, parses etc.) this processor to the data or is it only an filter? If an chain contains no consumer, the data is not processed.

Specified by:

isConsumer in interface DataProcessor

Returns:

true == yes

canResume

public boolean canResume()

Description copied from interface: DataProcessor

Supports this data processor resuming?

Specified by:

canResume in interface DataProcessor

Returns:

true == yes

resumeAt

public void resumeAt(long pByteOffset)

Description copied from interface: DataProcessor

Resumes the processing at the given position.

Specified by:

resumeAt in interface DataProcessor

Parameters:

pByteOffset - The offset position in bytes.
