Method Detail

doGetOutputFile

protected File doGetOutputFile()
Description copied from class: AbstractRetrievalPostProcessor
Abstract method that subclasses must provide to identify the output file for the post-processor's retrieval content.

Specified by:
doGetOutputFile in class AbstractRetrievalPostProcessor
Returns:
the output file.

getFileLock

protected Object getFileLock()
Description copied from class: AbstractRetrievalPostProcessor
Returns an object that can be used to synchronize writing to the output file. Superclasses should override this method and return the object used as a lock by other objects that read or otherwise interact with the output file.

Overrides:
getFileLock in class AbstractRetrievalPostProcessor
Returns:
an object to use for read/write synchronization, or null if no lock is needed.

getFileStore

protected FileStore getFileStore()

handleSuccessfulRetrieval

protected ByteBuffer handleSuccessfulRetrieval()
Description copied from class: AbstractRetrievalPostProcessor
Process the retrieved data if it has been retrieved successfully.

Overrides:
handleSuccessfulRetrieval in class AbstractRetrievalPostProcessor
Returns:
a buffer containing the downloaded data, perhaps converted during content handling.

handleXMLContent

protected ByteBuffer handleXMLContent()
                               throws IOException
Description copied from class: AbstractRetrievalPostProcessor
Handles XML content. The default implementation only calls AbstractRetrievalPostProcessor.logTextBuffer(java.nio.ByteBuffer) and returns.

Overrides:
handleXMLContent in class AbstractRetrievalPostProcessor
Returns:
a buffer containing the retrieved XML.
Throws:
IOException - if an IO error occurs while processing the data.

markResourceAbsent

protected void markResourceAbsent()
Description copied from class: AbstractRetrievalPostProcessor
Marks the retrieval target absent. Subclasses should override this method if they keep track of absent-resources. The default implementation does nothing.

Overrides:
markResourceAbsent in class AbstractRetrievalPostProcessor
