Method Detail

endOffset

public static int endOffset(int value)

Get the end offset of an ASCII encoded value.

Parameters:

value - to find the end encoded character offset.

Returns:

the offset at which the encoded value will end.

endOffset

public static int endOffset(long value)

Get the end offset of an ASCII encoded value.

Parameters:

value - to find the end encoded character offset.

Returns:

the offset at which the encoded value will end.

getDigit

public static int getDigit(int index,
                           byte value)

Get the digit value of an ASCII encoded byte.

Parameters:

index - within the string the value is encoded.

value - of the encoding in ASCII.

Returns:

the digit value of the encoded ASCII.

Throws:

java.lang.NumberFormatException - if the value is not a digit.

getDigit

public static int getDigit(int index,
                           char value)

Get the digit value of an ASCII encoded char.

Parameters:

index - within the string the value is encoded.

value - of the encoding in ASCII.

Returns:

the digit value of the encoded ASCII.

Throws:

java.lang.NumberFormatException - if the value is not a digit.

parseIntAscii

public static int parseIntAscii(java.lang.CharSequence cs,
                                int index,
                                int length)

Parse an ASCII encoded int from a CharSequence.

Parameters:

cs - to parse.

index - at which the number begins.

length - of the encoded number in characters.

Returns:

the parsed value.

parseLongAscii

public static long parseLongAscii(java.lang.CharSequence cs,
                                  int index,
                                  int length)

Parse an ASCII encoded long from a CharSequence.

Parameters:

cs - to parse.

index - at which the number begins.

length - of the encoded number in characters.

Returns:

the parsed value.
