      • getLong

        public long getLong(byte[] buffer,
                    int bufOffset)
        Description copied from class: PackedDecimalAsLongField
        Answer a long value from the given byte array buffer, at the bufOffset + offset of this field.

        Note: the data is not checked for valid decimal digits, although the sign nibble is checked for a valid value in the range x'A'-x'F'.

        Specified by:
        getLong in interface LongAccessor
        Overrides:
        getLong in class PackedDecimalAsLongField
        Parameters:
        buffer - the byte array
        bufOffset - the additional offset into the byte array
        Returns:
        long

      • getLong

        public long getLong(byte[] buffer)
        Description copied from class: PackedDecimalAsLongField
        Answer a long value from the given byte array buffer, at the offset of this field.

        Note: the data is not checked for valid decimal digits, although the sign nibble is checked for a valid value in the range x'A'-x'F'.

        Specified by:
        getLong in interface LongAccessor
        Overrides:
        getLong in class PackedDecimalAsLongField
        Parameters:
        buffer - the byte array
        Returns:
        long

      • putLong

        public void putLong(long value,
                    byte[] buffer,
                    int bufOffset)
             throws java.lang.IllegalArgumentException
        Description copied from class: PackedDecimalAsLongField
        Put a long value into the given byte array buffer, at the bufOffset + offset of this field.

        Note: If the field is unsigned, a x'F' is supplied as the sign nibble in the field.

        Specified by:
        putLong in interface LongAccessor
        Overrides:
        putLong in class PackedDecimalAsLongField
        Parameters:
        value - the signed int value
        buffer - the byte array
        bufOffset - the additional offset into the byte array
        Throws:
        java.lang.IllegalArgumentException - if the value is out of range

      • putLong

        public void putLong(long value,

        Parameters:
        value - the signed int value
        buffer - the byte array
        Throws:
        java.lang.IllegalArgumentException - if the value is out of range
