Throws:

IOException

isDataAvailable

public boolean isDataAvailable()

getBytesWritten

public long getBytesWritten()

getBytesRead

interrupt

public void interrupt()

Description copied from interface: CommunicationsSession

Asynchronously interrupts this FlowFileCodec. Implementations must ensure that they stop sending and receiving data as soon as possible after this method has been called, even if doing so results in sending only partial data to the peer. This will usually result in the peer throwing a SocketTimeoutException.

isClosed

public boolean isClosed()

Returns:

true if the connection is closed, false otherwise

close

public void close()
           throws IOException

Throws:

IOException

getChecksum

public String getChecksum()

setChecksum

public void setChecksum(String checksum)

setDataTransferUrl

public void setDataTransferUrl(String dataTransferUrl)

Parameters:

dataTransferUrl - Set data transfer url to use as provenance event transit url.

createTransitUri

public String createTransitUri(String communicantUrl,
                               String sourceFlowFileIdentifier)

Specified by:

createTransitUri in interface CommunicationsSession

Overrides:

createTransitUri in class AbstractCommunicationsSession

Parameters:

communicantUrl - Communicant's url that this session is assigned to.

sourceFlowFileIdentifier - Source Flow-file's uuid.

Returns:

A transit uri to be used in a provenance event.
