Field Summary

static int	ASCII_DATA_TYPE Default transfer type, intended primarily for the transfer of text files except when both hosts would find EBCDIC more convenient.
static int	BLOCK_DATA_TRANSMISSION_MODE The file is transmitted as a series of data blocks preceded by one or more header bytes.
static int	COMPRESSED_DATA_TRANSMISSION_MODE There are three kinds of information to be sent : regular data, sent in a byte string; compressed data, consisting of replications or filler; and control information, sent in a two-byte escape sequence.
static int	DEFAULT_FTP_PORT Default FTP port value is '21'.
static java.util.Locale	DEFAULT_LOCALE Default Locale used when none is provided at construction time.
static int	EBCDIC_DATA_TYPE Intended for efficient transfer between hosts which use EBCDIC for their internal character representation.
static int	FILE_DATA_STRUCTURE Default structure assumed if the setTransferStructure has not been used.
static int	IMAGE_DATA_TYPE Data are sent as contiguous bits which, for transfer, are packed into the 8-bit transfer bytes.
static int	LOCAL_DATA_TYPE Data is transferred in logical bytes of the size specified by the obligatory sceond parameter, Byte size.
static int	PAGE_DATA_STRUCTURE To transmit files that are discontinuous, FTP defines a page structure.
static int	RECORD_DATA_STRUCTURE Record structures must be accepted for "text" files (i.e., files with ASCII or EBCDIC types) by all FTP implementations.
static int	STREAM_DATA_TRANSMISSION_MODE The data is transmitted as a stream of bytes.

Field Detail

DEFAULT_LOCALE

public static final java.util.Locale DEFAULT_LOCALE

Default Locale used when none is provided at construction time.

Since:

v1.0

DEFAULT_FTP_PORT

public static final int DEFAULT_FTP_PORT

Default FTP port value is '21'.

Since:

v1.0

See Also:

"RFC959-??", Constant Field Values

ASCII_DATA_TYPE

public static final int ASCII_DATA_TYPE

Default transfer type, intended primarily for the transfer of text files except when both hosts would find EBCDIC more convenient.

Since:

v1.0

See Also:

"RFC959-3:1:1:1", Constant Field Values

EBCDIC_DATA_TYPE

public static final int EBCDIC_DATA_TYPE

Intended for efficient transfer between hosts which use EBCDIC for their internal character representation.

Since:

v1.0

See Also:

"RFC959-3:1:1:2", Constant Field Values

IMAGE_DATA_TYPE

public static final int IMAGE_DATA_TYPE

Data are sent as contiguous bits which, for transfer, are packed into the 8-bit transfer bytes. [API DISCUSSION : wouldn't you prefer 'BINARY_DATA_TYPE']

Since:

v1.0

See Also:

"RFC959-3:1:1:3", Constant Field Values

LOCAL_DATA_TYPE

public static final int LOCAL_DATA_TYPE

Data is transferred in logical bytes of the size specified by the obligatory sceond parameter, Byte size.

Since:

v1.0

See Also:

"RFC959-3:1:1:4", Constant Field Values

FILE_DATA_STRUCTURE

public static final int FILE_DATA_STRUCTURE

Default structure assumed if the setTransferStructure has not been used. There is no internal structure and the file is considered to be a continuous sequence of data bytes.

Since:

v1.0

See Also:

"RFC959-3:1:2:1", Constant Field Values

RECORD_DATA_STRUCTURE

public static final int RECORD_DATA_STRUCTURE

Record structures must be accepted for "text" files (i.e., files with ASCII or EBCDIC types) by all FTP implementations.

Since:

v1.0

See Also:

"RFC959-3:1:2:2", Constant Field Values

PAGE_DATA_STRUCTURE

public static final int PAGE_DATA_STRUCTURE

To transmit files that are discontinuous, FTP defines a page structure. File of this type are sometimes known as "random access files" or even as "holey files". In these files there is sometimes other information associated with the file as a whole (e.g., a file descriptor), or with a section of the file (e.g., page access controls), or both. In FTP, the sections of the file are called pages. each page is sent with a page header.

Since:

v1.0

See Also:

"RFC959-3:1:2:3", Constant Field Values

STREAM_DATA_TRANSMISSION_MODE

public static final int STREAM_DATA_TRANSMISSION_MODE

The data is transmitted as a stream of bytes. There is no restriction on the representation type used; record structures are allowed.

Since:

v1.0

See Also:

"RFC959-3:4:1", Constant Field Values

BLOCK_DATA_TRANSMISSION_MODE

public static final int BLOCK_DATA_TRANSMISSION_MODE

The file is transmitted as a series of data blocks preceded by one or more header bytes. Record structures are allowed in this mode, and any representation type may be used.

Since:

v1.0

See Also:

"RFC959-3:4:2", Constant Field Values

COMPRESSED_DATA_TRANSMISSION_MODE

public static final int COMPRESSED_DATA_TRANSMISSION_MODE

There are three kinds of information to be sent : regular data, sent in a byte string; compressed data, consisting of replications or filler; and control information, sent in a two-byte escape sequence. Compressed mode is useful for obtaining increased bandwidth on very large netword transmissions at a litle extra CPU cost. It can be most effectively used to reduce the size of printer files such as those generated by RJE hosts.

Since:

v1.0

"RFC959-3:4:3", Constant Field Values
