Method Details

getFastLong

public static long getFastLong(byte[] bytes,
 long minVal,
 long maxVal)
                        throws NumberFormatException

Optimised byte[] to number parser. This code does not handle null values, so the caller must do checkResultSet and handle null values prior to calling this function. Fraction part is discarded.

Parameters:

bytes - integer represented as a sequence of ASCII bytes

Returns:

The parsed number.

Throws:

NumberFormatException - If the number is invalid or the out of range for fast parsing. The value must then be parsed by another (less optimised) method.
