Method Detail

isEmpty

public static boolean isEmpty(String s)

Deprecated.

Returns true if the passed string is null or zero-length; false otherwise (including a string containing only whitespace). This is a replacement for the Jakarta Commons method with the same name.

isBlank

public static boolean isBlank(String s)

Deprecated.

Returns true if the passed string is null, zero-length, or contains only whitespace characters as defined by Character.isWhitespace(); false otherwise. This is a replacement for the Jakarta Commons method with the same name.

trimToEmpty

public static String trimToEmpty(String s)

Deprecated.

Trims all whitespace characters (as defined by Character.isWhitespace()) from both ends of the string, returning an empty string if there's nothing left. Will also return an empty string if passed null. This is a replacement for the Jakarta Commons method with the same name.

parseDigit

public static int parseDigit(char c,
             int base)

Deprecated.

Parses the passed character as a digit in the specified base, returning its value. Bases > 10 are represented by ASCII letters in the range A to Z (or a to z). Base 36 is the largest supported.

Returns:

The value, or -1 if the character is not a valid digit in the specified base (this method will typically be used in a loop, so no good reason to force exception checking).
