Constructor Details

XMLTransport

public XMLTransport(LoggerIfc logger,
 ConfigIfc config,
 File scratchDir)
             throws Exception

Construct a new XMLTransport to be used within the specified EINode.

Throws:

Exception

Method Details

isDataAvailable

public boolean isDataAvailable()

This method is used by the DataReceiver to ask this provider if data is available.

Specified by:

isDataAvailable in interface DataProviderIfc

Specified by:

isDataAvailable in class EITransport

Returns:

true, if data is available

getData

public DCFieldContainer getData()

This method is used by the DataReceiver to fetch a single DCFieldContainer.

Specified by:

getData in interface DataProviderIfc

Specified by:

getData in class EITransport

Returns:

DCFieldContainer.

getBulkData

public DCFieldContainer[] getBulkData()

This method is used by the DataReceiver to fetch several DCFieldContainer objects.

Specified by:

getBulkData in interface DataProviderIfc

Specified by:

getBulkData in class EITransport

Returns:

DCFieldContainer object array, containing the data that is for processing

setProcessor

public void setProcessor(XMLProcessor processor)

run

public void run()

This method is used when the EITransport runs within its own thread. The method should contain the logic to retrieve the data from the the transport's data source and to generate the DCFieldContainer() objects that will be passed on to the DataReceiver.

Specified by:

run in interface Runnable

Specified by:

run in class EITransport

shutdown

public void shutdown()

Stop the transport. To ensure no loss of data, the transport should continue to supply any queued data to its DataReceiver.

Specified by:

shutdown in interface DCTransport

Specified by:

shutdown in class EITransport

initialize

public void initialize()
                throws Exception

This function is used to create and initialize the Transport's components.

Throws:

Exception

initFilenameFilter

protected void initFilenameFilter()
                           throws Exception

This function is used to initialize the filename filter

Throws:

Exception

initStreamSource

protected abstract void initStreamSource()
                                  throws Exception

This is to be implemented by subclasses for various transportation types.

Throws:

Exception
