Method Detail

getEbcdicLength

public static int getEbcdicLength(String strText,
                                  int ccsid)

Return the length in EBCBIC bytes of this Unicode String

getEbcdicLength

public static int getEbcdicLength(String strText,
                                  int ccsid,
                                  boolean isPureDbcs)

Return the length in EBCBIC bytes of this Unicode String

getEbcdicLengthWithEmbeddedShifts

public static int getEbcdicLengthWithEmbeddedShifts(String strText,
                                                    int ccsid)

If a Unicode string already has shift characters embedded what is its length in EBCDIC bytes. We still need to consider that DBCS characters are double width and that lam + alef is only 1 character.

Returns:

pad

public static String pad(String strText,
                         int targetLength,
                         char c,
                         int ccsid)

Pad this Unicode string to the desired length in EBCDIC bytes with the given character

truncate

public static String truncate(String strText,
                              int targetLength,
                              int ccsid,
                              boolean isPureDbcs)

Truncate this Unicode string to the desired length in EBCDIC bytes If it is too short, return as is

substring

public static String substring(String string,
                               int start,
                               int end,
                               int ccsid)

Return the Unicode substring of the given Unicode string given the EBCDIC byte offsets
