Method Detail

close

public void close()
           throws IOException

Specified by:

close in interface Closeable

Specified by:

close in interface AutoCloseable

Overrides:

close in class BasicSource

Throws:

IOException

setResource

public CsvSource setResource(InputStream data)

Provided to connect an existing input stream to this CSV parser source. Overrides the resource specified to the constructor.

Parameters:

data -

isEof

public boolean isEof()

Description copied from interface: Source

Is the source at EOF? Not all sources are bounded, so they may always return false.

Specified by:

isEof in interface Source

Overrides:

isEof in class BasicSource

Returns:

true if the source is at EOF

internalGetNextMessage

protected MessageAndRouting internalGetNextMessage(StreamProcessingContext spc)
                                            throws IOException

Description copied from class: BasicSource

Get the next pending message, if any. This won't be called after a noteEndOfStream() call. The caller handles back-off, so it's not necessary to force a sleep during this call. The object has the instance synchronization lock during this call.

Specified by:

internalGetNextMessage in class BasicSource

Returns:

the next message, or null

Throws:

IOException
