Method Summary

Modifier and Type	Method	Description
protected java.io.File	doGetOutputFile()	Abstract method that subclasses must provide to identify the output file for the post-processor's retrieval content.
protected void	handleUnsuccessfulRetrieval()	Called when the retrieval state is other than Retriever.RETRIEVER_STATE_SUCCESSFUL.
protected boolean	isDeleteOnExit(java.io.File outFile)	Indicates whether the output file should have its delete-on-exit flag set so that it's deleted when the JVM terminates.
protected void	markResourceAbsent()	Marks the retrieval target absent.
protected boolean	overwriteExistingFile()	Indicates whether the retrieved data should be written to the output file if a file of the same name already exists.

Method Detail

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 class AbstractRetrievalPostProcessor

Returns:

the output file.

isDeleteOnExit

protected boolean isDeleteOnExit(java.io.File outFile)

Description copied from class: AbstractRetrievalPostProcessor

Indicates whether the output file should have its delete-on-exit flag set so that it's deleted when the JVM terminates.

Overrides:

isDeleteOnExit in class AbstractRetrievalPostProcessor

Parameters:

outFile - the output file.

Returns:

true if the output file's delete-on-exit flag should be set, otherwise false.

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 class AbstractRetrievalPostProcessor

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 class AbstractRetrievalPostProcessor

handleUnsuccessfulRetrieval

protected void handleUnsuccessfulRetrieval()

Description copied from class: AbstractRetrievalPostProcessor

Called when the retrieval state is other than Retriever.RETRIEVER_STATE_SUCCESSFUL. Can be overridden by subclasses to handle special error cases. The default implementation calls AbstractRetrievalPostProcessor.markResourceAbsent() if the retrieval state is Retriever.RETRIEVER_STATE_ERROR.

Overrides:

handleUnsuccessfulRetrieval in class AbstractRetrievalPostProcessor
