Method Detail

getRemoteFileName

public java.lang.String getRemoteFileName()

Description copied from interface: IIncomingFileTransfer

Obtains the name of the remote file if possible. The name will typically but not necessarily be the same as the leaf part of the path to the remote file.

Specified by:

getRemoteFileName in interface IIncomingFileTransfer

Overrides:

getRemoteFileName in class AbstractRetrieveFileTransfer

Returns:

The name of the remote file or null if no such name can be determined.

cancel

public void cancel()

Description copied from interface: IFileTransfer

Cancel this file transfer. If file transfer has already been completed, then this method has no effect. If the file transfer has not been completed then calling this method will result in an IFileTransferEvent being delivered to the IFileTransferListener indicating that transfer is done (IFileTransfer.isDone() returns true), and some exception will be made available

Specified by:

cancel in interface IFileTransfer

Overrides:

cancel in class AbstractRetrieveFileTransfer
