Method Detail

• packedNybblesToInt

  private static final int packedNybblesToInt​(byte[] buffer,
                                              int offset,
                                              int startNybble,
                                              int numberOfNybbles)

  Convert a range of packed nybbles (up to 9 digits without overflow) to an int. Note that for performance purpose, it does not do array-out-of-bound checking.

• packedNybblesToLong

  private static final long packedNybblesToLong​(byte[] buffer,
                                                int offset,
                                                int startNybble,
                                                int numberOfNybbles)

  Convert a range of packed nybbles (up to 18 digits without overflow) to a long. Note that for performance purpose, it does not do array-out-of-bound checking.

• computeMagnitude

  private static final int[] computeMagnitude​(int[] input)

  Compute the int array of magnitude from input value segments.

• getBigDecimal

  static java.math.BigDecimal getBigDecimal​(byte[] buffer,
                                            int offset,
                                            int precision,
                                            int scale)

  Build a java.math.BigDecimal from a fixed point decimal byte representation.

  Throws:

  java.lang.IllegalArgumentException - if the specified representation is not recognized.

• getDouble

  static double getDouble​(byte[] buffer,
                          int offset,
                          int precision,
                          int scale)

  Build a Java double from a fixed point decimal byte representation.

  Throws:

  java.lang.IllegalArgumentException - if the specified representation is not recognized.

• getLong

  static long getLong​(byte[] buffer,
                      int offset,
                      int precision,
                      int scale)

  Build a Java long from a fixed point decimal byte representation.

  Throws:

  java.lang.IllegalArgumentException - if the specified representation is not recognized.

  java.lang.ArithmeticException - if value is too large for a long

• bigDecimalToPackedDecimalBytes

  public static final int bigDecimalToPackedDecimalBytes​(byte[] buffer,
                                                         int offset,
                                                         java.math.BigDecimal b,
                                                         int declaredPrecision,
                                                         int declaredScale)
                                                  throws SqlException

  Write a Java java.math.BigDecimal to packed decimal bytes.

  Throws:

  SqlException
