Method Detail

leftTrim

@Deprecated
public static final String leftTrim(String string)

Deprecated. Use Const.ltrim(String) instead

rightTrim

@Deprecated
public static final String rightTrim(String string)

Deprecated. Use Const.rtrim(String) instead

isSpace

@Deprecated
public static final boolean isSpace(char c)

Deprecated. Use Const.isSpace(char) instead

                     Object data)
                              throws KettleValueException

Change a hexadecimal string into normal ASCII representation. E.g. if Value contains string "61" afterwards it would contain value "a". If the hexadecimal string is of odd length a leading zero will be used. Note that only the low byte of a character will be processed, this is for binary transformations.

Returns:

Change a string into its hexadecimal representation. E.g. if Value contains string "a" afterwards it would contain value "0061". Note that transformations happen in groups of 4 hex characters, so the value of a characters is always in the range 0-65535.

Returns:

Change a string into its hexadecimal representation. E.g. if Value contains string "a" afterwards it would contain value "0061". Note that transformations happen in groups of 4 hex characters, so the value of a characters is always in the range 0-65535.

Returns:

A string with Hex code

Throws:

                              throws KettleValueException

Change a hexadecimal string into normal ASCII representation. E.g. if Value contains string "61" afterwards it would contain value "a". If the hexadecimal string is of a wrong length leading zeroes will be used. Note that transformations happen in groups of 4 hex characters, so the value of a characters is always in the range 0-65535.

Returns:

A hex-to-char decoded String

Throws:

KettleValueException
