Constructor Detail

### SSTRecord

    public SSTRecord()

### SSTRecord

    public SSTRecord(RecordInputStream in)

  Fill the fields from the data

  The data consists of sets of string data. This string data is arranged as follows:

  ``

       short  string_length;   // length of string data
       byte   string_flag;     // flag specifying special string
                               // handling
       short  run_count;       // optional count of formatting runs
       int    extend_length;   // optional extension length
       char[] string_data;     // string data, can be byte[] or
                               // short[] (length of array is
                               // string_length)
       int[]  formatting_runs; // optional formatting runs (length of
                               // array is run_count)
       byte[] extension;       // optional extension (length of array
                               // is extend_length)

  The string_flag is bit mapped as follows:

  Bit number | Meaning if 0 | Meaning if 1
  --- | --- | ---
  0 | string_data is byte[] | string_data is short[]
  1 | Should always be 0 | string_flag is defective
  2 | extension is not included | extension is included
  3 | formatting run data is not included | formatting run data is included
  4 | Should always be 0 | string_flag is defective
  5 | Should always be 0 | string_flag is defective
  6 | Should always be 0 | string_flag is defective
  7 | Should always be 0 | string_flag is defective

  We can handle eating the overhead associated with bits 2 or 3 (or both) being set, but we have no idea what to do with the associated data. The UnicodeString class can handle the byte[] vs short[] nature of the actual string data

  Parameters:
    `in` - the RecordInputstream to read the record from

Method Detail

### addString

    public int addString(UnicodeString string)

  Add a string.

  Parameters:
    `string` - string to be added
  Returns:
    the index of that string in the table

### getNumStrings

    public int getNumStrings()

  Returns:
    number of strings

### getNumUniqueStrings

    public int getNumUniqueStrings()

  Returns:
    number of unique strings

### getString

    public UnicodeString getString(int id)

  Get a particular string by its index

  Parameters:
    `id` - index into the array of strings
  Returns:
    the desired string

### toString

    public java.lang.String toString()

  Return a debugging string representation

  Overrides:
    `toString` in class `Record`
  Returns:
    string representation

### getSid

    public short getSid()

  Description copied from class: `Record`
  return the non static version of the id for this record.

  Specified by:
    `getSid` in class `Record`

### serialize

    protected void serialize(ContinuableRecordOutput out)

  Description copied from class: `ContinuableRecord`
  Serializes this record's content to the supplied data output.
  The standard BIFF header (ushort sid, ushort size) has been handled by the superclass, so only BIFF data should be written by this method. Simple data types can be written with the standard `LittleEndianOutput` methods. Methods from `ContinuableRecordOutput` can be used to serialize strings (with `ContinueRecord`s being written as required). If necessary, implementors can explicitly start `ContinueRecord`s (regardless of the amount of remaining space).

  Specified by:
    `serialize` in class `ContinuableRecord`
  Parameters:
    `out` - a data output stream

### createExtSSTRecord

    public ExtSSTRecord createExtSSTRecord(int sstOffset)

  Creates an extended string record based on the current contents of the current SST record. The offset within the stream to the SST record is required because the extended string record points directly to the strings in the SST record.

  NOTE: THIS FUNCTION MUST ONLY BE CALLED AFTER THE SST RECORD HAS BEEN SERIALIZED.

  Parameters:
    `sstOffset` - The offset in the stream to the start of the SST record.
  Returns:
    The new SST record.

### calcExtSSTRecordSize

    public int calcExtSSTRecordSize()

  Calculates the size in bytes of the EXTSST record as it would be if the record was serialized.

  Returns:
    The size of the ExtSST record in bytes.
