Method Detail

parseBigIntegerString

public java.math.BigInteger parseBigIntegerString(byte[] str,
                                                  int offset,
                                                  int length,
                                                  int radix)
                                           throws java.lang.NumberFormatException

Parses a BigIntegerLiteral as specified in JavaBigIntegerParser.

Parameters:

str - the input string

offset - the start of the string

length - the length of the string

radix - the radix of the number

Returns:

the parsed value (always non-null)

Throws:

java.lang.NumberFormatException - if parsing fails
