Method Detail

getFileName

java.lang.String getFileName()
                      throws java.io.IOException

Returns:

The uploaded file name

Throws:

java.io.IOException - If failed to resolve the name

getEventListenerFilePath

java.nio.file.Path getEventListenerFilePath()

Returns:

The Path to use when invoking the ScpTransferEventListener

getPermissions

java.util.Collection<java.nio.file.attribute.PosixFilePermission> getPermissions()
                                                                          throws java.io.IOException

Returns:

The permissions to be used for uploading a file

Throws:

java.io.IOException - If failed to generate the required permissions

getTimestamp

ScpTimestamp getTimestamp()
                   throws java.io.IOException

Returns:

The ScpTimestamp to use for uploading the file if null then no need to send this information

Throws:

java.io.IOException - If failed to generate the required data

getSize

long getSize()
      throws java.io.IOException

Returns:

An estimated size of the expected number of bytes to be uploaded. If non-positive then assumed to be unknown.

Throws:

java.io.IOException - If failed to generate an estimate

resolveSourceStream

java.io.InputStream resolveSourceStream(Session session,
                                        long fileSize,
                                        java.util.Set<java.nio.file.attribute.PosixFilePermission> permissions,
                                        java.nio.file.OpenOption... options)
                                 throws java.io.IOException

Parameters:

session - The Session through which file is transmitted

fileSize - The expected transfer byte count

permissions - The requested file permissions

options - The OpenOptions may be null/empty

Returns:

The InputStream containing the data to be uploaded

Throws:

java.io.IOException - If failed to create the stream

closeSourceStream

default void closeSourceStream(Session session,
                               long fileSize,
                               java.util.Set<java.nio.file.attribute.PosixFilePermission> permissions,
                               java.io.InputStream stream)
                        throws java.io.IOException

Called when the stream obtained from resolveSourceStream is no longer needed since since file copy was completed successfully.

Parameters:

session - The Session through which file is transmitted

fileSize - The expected transfer byte count

permissions - The requested file permissions

stream - The InputStream to close

Throws:

java.io.IOException - If failed to close the stream - Note: stream will be closed regardless of whether this method throws an exception or not.
