Method Detail

leftTrim

public static final String leftTrim(String string)

Deprecated. Use Const.ltrim(String) instead

rightTrim

public static final String rightTrim(String string)

Deprecated. Use Const.rtrim(String) instead

isSpace

public static final boolean isSpace(char c)

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:

Value itself

Throws:

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:

Throws:

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 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
