Method Detail

getProcessorName

public String getProcessorName()

Specified by:

getProcessorName in interface FileProcessor

Returns:

A displayable name for this processor.

init

public void init(net.sf.sfac.setting.Settings sett)

Description copied from interface: FileProcessor

Initialize this file processor just after instantiation (called only once).
The settings passed here should be use to store all persistent data.

Specified by:

init in interface FileProcessor

Parameters:

sett - Settings for this FileProcessor instance.

getInputCardinality

public int getInputCardinality()

getOutputCardinality

public int getOutputCardinality(int inputCardinality)

Description copied from interface: FileProcessor

Get the number of output streams generated for the given number of input streams.
possible values are:

• NONE
• ONE
• MANY

Specified by:

getOutputCardinality in interface FileProcessor

Parameters:

inputCardinality - ONE or MANY.

process

public void process(InputStream is,
                    InputFileInfo line,
                    FileProcessorEnvironment env)
             throws IOException

Description copied from interface: FileProcessor

Request to process the given input stream.
The output stream to use for output should be requested to the FileProcessorEnvironment.

Specified by:

process in interface FileProcessor

Parameters:

is - the InputStream to process

line - Information about the input file to process

env - object used by this FileProcessor to interact with its environment.

Throws:

IOException - if something goes wrong.

startBatch

public void startBatch(FileProcessorEnvironment env)

Description copied from interface: FileProcessor

Notification that the processing of a batch of file is starting.
This method allows to initialize this FileProcessor before each file batch processing.

Specified by:

startBatch in interface FileProcessor

endBatch

public void endBatch(FileProcessorEnvironment env)

Description copied from interface: FileProcessor

Notification that the current batch is finished.

Specified by:

endBatch in interface FileProcessor

getStatusMessage

public String getStatusMessage()

Description copied from interface: FileProcessor

Get the status of this processor to display in the status bar of the GUI during file processing.

Warning: this method is called in a different Thread from the processing Thread (the Thread calling the process(..) method). It is usually called from the swing EventDispatchThread. So, be aware of possible threading synchronization problems while accessing the instance variables of your class.

Specified by:

getStatusMessage in interface FileProcessor

Returns:

the status of this processor.

getEditor

public net.sf.sfac.gui.editor.ObjectEditor getEditor()

Description copied from interface: FileProcessor

Get a GUI editor for this object.

Specified by:

getEditor in interface FileProcessor
