Constructor Detail

AbstractTransferService

public AbstractTransferService(ServerContext serverCtx,
                       TransferServiceTask trTask,
                       AbstractTransferJob job)

Method Detail

execute

public abstract void execute()
                      throws java.lang.Exception

Description copied from interface: Executable

Contains the code to be executed. This method is to be called in order to execute the code synchronously. In this case no other execution thread is involved.

Specified by:

execute in interface Executable

Throws:

java.lang.Exception

getRealFileSize

public final long getRealFileSize()

getFileDataType

public final FileDataType getFileDataType()

getTransferConnection

public final ServerTransferConnection getTransferConnection()

getServerFile

public final java.io.File getServerFile()

getTransferJob

public AbstractTransferJob getTransferJob()

getTaskId

public final TaskId getTaskId()

Description copied from interface: TaskIdHolder

Returns the unique identifier for this task. This identifier is only valid for a single task execution. When the same task instance executes another time then it will have a new TaskId.

Specified by:

getTaskId in interface TaskIdHolder

cancel

public final void cancel()

Description copied from interface: LocalCancellableTask

Cancels the running task. Note that this call puts the task in a CANCEL_REQUESTED state. Once this happened CancellableTask.wasCancelled() will return true. Actually this call cancels the task's current Future and enforces a CancellationException to be thrown.

Specified by:

cancel in interface LocalCancellableTask

wasCancelled

public final boolean wasCancelled()

Description copied from interface: CancellableTask

Tells whether ever an attempt has been made to cancel this task.

Specified by:

wasCancelled in interface CancellableTask

isTransferZipped

public final boolean isTransferZipped()

wasFoundZippedOnServer

public final boolean wasFoundZippedOnServer()

downloadFileData

public final void downloadFileData()
                            throws java.io.IOException

Throws:

java.io.IOException

getServerFileInfo

protected java.lang.String getServerFileInfo()
