Method Detail

getPriority

int getPriority()

Gets the priority that permits to sort the processor list to execute.
The more the value of the priority is high, the more the processor is executed first.
The chained execution of processors that have the same priority could be known.
By default, the priority is set to 50.

Returns:

the priority value.

processBefore

String processBefore(String path,
                     SilverpeasFileProcessor.ProcessingContext context)

Processes the specified path and returns the new path of the SilverpeasFile to get. This method is triggered before retrieving the SilverpeasFile matching a given file path. If nothing should be done with the path, then just returns the path passed as argument.

Parameters:

path - the path of the asked file.

context - the processing context.

Returns:

either the specified path or a new path of the asked file.

processAfter

SilverpeasFile processAfter(SilverpeasFile file,
                            SilverpeasFileProcessor.ProcessingContext context)

Processes the specified SilverpeasFile and returns the new one. This method is triggered after retrieving the SilverpeasFile. If nothing should be done with the path, then just returns the SilverpeasFile instance passed as argument.

Parameters:

file - the SilverpeasFile to process.

context - the processing context.

Returns:

either the specified one or a new one.
