getInitiatorEntityId

public long getInitiatorEntityId()

getBucketName

public String getBucketName()

Description copied from interface: FileTransfer

return the name of the bucket where the file is being transfered to/from.

Could be null for incoming transfers. For the CFDP service, the bucket is determined by the source or destination entity id and it is not null. However if the bucket was determined by the filename which is known only when the metadata packet is received, this could be null.

getObjectName

public String getObjectName()

Description copied from interface: FileTransfer

return the name of the object (file) which is being transfered. This is the filename on the local (Yamcs) site.

Can be null for incoming transfers - for example CFDP can start a transfer without knowing the filename if the first metadata packet has been lost.

getOriginalObjectName

public String getOriginalObjectName()

getRemotePath

public String getRemotePath()

Description copied from interface: FileTransfer

return the remote path of the file which is being transfered.

Can be null for incoming transfers - for example CFDP can start a transfer without having this information if the first metadata packet has been lost.

getDirection

public TransferDirection getDirection()

getTotalSize

public long getTotalSize()

Description copied from interface: FileTransfer

return the file size in bytes or -1 if the size is not known.

For the CFDP service the incoming files can be unbounded (but this is not yet supported) or the size will be part of the metadata packet which may be missing.

getTransferredSize

public long getTransferredSize()

getDirectoryListingResponse

public DirectoryListingResponse getDirectoryListingResponse()

getFileData

public byte[] getFileData()

getOriginatingTransactionId

public CfdpTransactionId getOriginatingTransactionId()
