Method Details

shutdown

public void shutdown()

getFilenameGenerator

public final FilenameGenerator getFilenameGenerator()

setFilenameGenerator

public final void setFilenameGenerator(FilenameGenerator filenameGen)

readOSARsFromFile

public OSAR[] readOSARsFromFile(File osarFile)

readOSARs

public OSAR[] readOSARs()

This method reads all OSARs from the oldest archive file in the node's input directory and returns an OSAR array to the caller. Current functionality allows only for a bulk read of OSARs from archive files in the input directory. Much more file management must be added to allow the reading of single OSARs from the input directory.

deleteOSARs

public boolean deleteOSARs()

This method deletes the OSAR file in the node's input directory from which the latest batch of OSARs has been processed.

writeOSARs

public boolean writeOSARs(OSAR[] osars)

This method writes OSARs to the node's output directory.

writeOSAR

public boolean writeOSAR(OSAR osar)

The writeOSAR() method stores an OSAR in the current cache file. When the cache file reaches the maximum number of OSARs, it is renamed to the node output directory, which makes it available to the LDM and RDM.

moveToArchive

public boolean moveToArchive()

checkInput

public boolean checkInput()

actionPerformed

public void actionPerformed(ActionEvent e)
