Member Function Documentation

◆ getBinaryFileImpl()

binary FileLocationHandler::FileLocationHandlerSftp::getBinaryFileImpl	(	string	scheme,
		string	location,
		*hash< auto >	opts
	)

private

Retrieves a binary file from the given location.

Parameters

scheme	the scheme being used
location	the location string without the scheme
opts	read options

Returns: the binary data of the file's contents, if it can be retrieved

Note: This method can throw any exception related to making an SFTP transfer

◆ getBinaryStreamImpl()

Qore::InputStream FileLocationHandler::FileLocationHandlerSftp::getBinaryStreamImpl	(	string	scheme,
		string	location,
		*hash< auto >	opts
	)

private

Retrieves a binary file from the given location.

Parameters

scheme	the scheme being used
location	the location string without the scheme
opts	read options

Returns: an input stream of the file's contents, if it can be retrieved

Note: This method can throw any exception related to making an SFTP transfer

◆ getIoPollerForLocationImpl()

Qore::AbstractPollOperation FileLocationHandler::FileLocationHandlerSftp::getIoPollerForLocationImpl	(	string	scheme,
		string	location,
		*hash< auto >	opts
	)

private

Retrieves an I/O poller to retrieve a binary file from the given location.

Parameters

scheme	the scheme being used
location	the location string without the scheme
opts	read options

Returns: an I/O poller to retrieve the file's data

◆ getOutputStreamImpl()

OutputStreamWrapper FileLocationHandler::FileLocationHandlerSftp::getOutputStreamImpl	(	string	scheme,
		string	location,
		*hash< auto >	opts
	)

private

Returns an output stream for writing data to the given location.

Parameters

scheme	the scheme being used
location	the location string without the scheme
opts	write options

Returns: an output stream for writing to the file

Note

OutputStream::close() must be called to close the stream after writing terminates in order to avoid a deadlock
The data written to the OutputStreamWrapper object is written in the background; to ensure that the data has been written to the target, call OutputStreamWrapper::waitForIo()
This method can throw any exception related to making an SFTP transfer

◆ getReadOptionsImpl()

hash< string, hash< FileHandlerOptionInfo > > FileLocationHandler::FileLocationHandlerSftp::getReadOptionsImpl ( )

private

Gets supported read options.

Returns: supported read options

		string	location,
		*hash< auto >	opts
	)

private

Returns a stream reader for the file's data at the given location.

Parameters

scheme	the scheme being used
location	the location string without the scheme
opts	read options

Returns: a stream reader for the file's contents, if it can be retrieved

Note: This method can throw any exception related to making an SFTP transfer

◆ getTextFileImpl()

string FileLocationHandler::FileLocationHandlerSftp::getTextFileImpl	(	string	scheme,
		string	location,
		*hash< auto >	opts
	)

private

Retrieves a text file from the given location.

Parameters

scheme	the scheme being used
location	the location string without the scheme
opts	read options

Returns: the string of the file's contents, if it can be retrieved

Note: This method can throw any exception related to making an SFTP transfer

◆ getWriteOptionsImpl()

hash< string, hash< FileHandlerOptionInfo > > FileLocationHandler::FileLocationHandlerSftp::getWriteOptionsImpl ( )

private

Gets supported write options.

Returns: supported write options

◆ writeFileImpl()

FileLocationHandler::FileLocationHandlerSftp::writeFileImpl	(	string	scheme,
		string	location,
		data	contents,
		*hash< auto >	opts
	)

private

Writes data to a file at the given location.

Parameters

scheme	the scheme being used
location	the location string without the scheme
contents	the file's contents
opts	write options

Note: This method can throw any exception related to making an SFTP transfer
