Method Detail

parseLong

public static long parseLong(java.lang.String val)

Parameters:

val - max 16 characters long. Should not contain any '0x'-prefix. the empty string will return 0.

Throws:

java.lang.NumberFormatException - if val is longer than 16 characters or if val contains non parseable characters ([0-9, a-f, A-F] is legal).

java.lang.NullPointerException - if val is null.

parseInt(String)

parseInt

public static int parseInt(java.lang.String val)

parse a hex string into an int. This method differs from Integer.parseInt(val, 16) in that it does not allow '-' and allows the full range of eight hex characters (eg. 'FFFFFFFF' is allowed). Since int is signed the string is parsed in the standard signed 2-complement representaion, eg:

• 7FFFFFFF -> Integer.MAX_VALUE
• 80000000 -> Integer.MIN_VALUE
• FFFFFFFF -> -1

Parameters:

val - max 8 characters long. Should not contain any '0x'-prefix. the empty string will return 0.

Throws:

java.lang.NumberFormatException - if val is longer than 8 characters or if val contains non parseable characters ([0-9, a-f, A-F] is legal).

java.lang.NullPointerException - if val is null.

parseShort

public static short parseShort(java.lang.String val)

Parameters:

val - max 4 characters long. Should not contain any '0x'-prefix. the empty string will return 0.

Throws:

java.lang.NumberFormatException - if val is longer than 4 characters or if val contains non parseable characters ([0-9, a-f, A-F] is legal).

java.lang.NullPointerException - if val is null.
