getFileStore
protected FileStore getFileStore()
-
overwriteExistingFile
protected boolean overwriteExistingFile()
Description copied from class:AbstractRetrievalPostProcessor
Indicates whether the retrieved data should be written to the output file if a file of the same name already exists. The default implementation of this method returns false (files are not overwritten).- Overrides:
overwriteExistingFile
in classAbstractRetrievalPostProcessor
- Returns:
- true if an existing file should be overwritten, otherwise false.
-
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 classAbstractRetrievalPostProcessor
-
getFileLock
protected java.lang.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 classAbstractRetrievalPostProcessor
- Returns:
- an object to use for read/write synchronization, or null if no lock is needed.
-
doGetOutputFile
protected java.io.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 classAbstractRetrievalPostProcessor
- Returns:
- the output file.
-
handleSuccessfulRetrieval
protected java.nio.ByteBuffer handleSuccessfulRetrieval()
Description copied from class:AbstractRetrievalPostProcessor
Process the retrieved data if it has been retrieved successfully.- Overrides:
handleSuccessfulRetrieval
in classAbstractRetrievalPostProcessor
- Returns:
- a buffer containing the downloaded data, perhaps converted during content handling.
-
handleTextContent
protected java.nio.ByteBuffer handleTextContent() throws java.io.IOException
Description copied from class:AbstractRetrievalPostProcessor
Handles Text content. If the content type is text/xml,AbstractRetrievalPostProcessor.handleXMLContent()
is called. If the content type is text/html,AbstractRetrievalPostProcessor.handleHTMLContent()
is called. For all other sub-types the content is logged as a message with levelLevel.SEVERE
.- Overrides:
handleTextContent
in classAbstractRetrievalPostProcessor
- Returns:
- a buffer containing the retrieved text.
- Throws:
java.io.IOException
- if an IO error occurs while processing the data.
