| /** |
| * Serialize BigDecimal classes to/from DataInput and DataOutput objects. |
| * |
| * BigDecimal is comprised of a BigInteger with an integer 'scale' field. |
| * The BigDecimal/BigInteger can also return itself as a 'long' value. |
| * |
| * We serialize in one of two formats: |
| * |
| * First, check whether the BigInt can fit in a long: |
| * boolean b = BigIntegerPart > LONG_MAX || BigIntegerPart < LONG_MIN |
| * |
| * [int: scale][boolean: b == false][long: BigInt-part] |
| * [int: scale][boolean: b == true][string: BigInt-part.toString()] |
| * |
| * TODO(aaron): Get this to work with Hadoop's Serializations framework. |
| * |
| * @deprecated use org.apache.sqoop.lib.BigDecimalSerializer instead. |
| * @see org.apache.sqoop.lib.BigDecimalSerializer |
