  - ### getFoldingClass

    public String getFoldingClass()
    Retrieve the character folding class to be applied to data within the database.

    Character folding is used to indicate that language-specific character replacement should be performed. This is meaningful only for non-English text and is used to exchange certain characters with others based on phonetic similarity or difference, for example the sound of the Swedish national characters �, and � exist in the Norwegian language as well but they have different character representations, namely �, and �. So, if you use SWE as the folding class, these Norwegian characters will be converted to their Swedish equivalent when indexing and/or searching.

    This means that you can search for Norwegian words, names, etc. within a Swedish database, which can be very useful as national keyboards only have one variety of these phonetically similar characters and using tools such as the Windows character map is an annoyingly cumbersome option for end users.

    Note that you can also fold a Swedish/German/Norwegian/etc. database to ENG, which means that all diacritics are removed and just the base forms of characters are used.

    Folding as MUL (the default) means that no character conversion is performed.

    Returns:
      Folding class

  - ### setFoldingClass

    public void setFoldingClass(String folding)

    public void setUsesAutoReorg(boolean mode)
    Establish whether the database's index files should automatically reorganize, or whether the DBA should be alerted to the fact that the files are in need of reorganization.

    It is sometimes not possible to allow TRIP to automatically reorganize index files when indexing due to the length of time that this operation might take. When databases are very large, reorganzing the index can take considerable time, during which any attempt to search the database could result in an error being reported to the user. To avoid this ever happening, set this flag false and TRIP will simply report in the index logfile when the index files are in need of reorganization. The DBA can then schedule downtime for the database to perform such maintenance as is required.

      `mode` - true if index files are to be allowed to automatically reorganize when indexing

  - ### setUsesLogDeletes

    public void setUsesLogDeletes(boolean mode)

  - ### index

    public void index(boolean reindex, boolean batchjob) throws TdbException
    Request the current database to be indexed.

    Synchronous indexing is supported with TRIPsystem 7.0 and later. Note that indexing a database with a very large number of new or changed records may take a long time.

    If you index synchronously, best practise is to regularly schedule a regular index batch job. Not doing this may degrade performance over time.

    This method causes network I/O.

    Parameters:
      `reindex` - pass true to reindex the database and false to index incrementally
      `batchjob` - pass true to index in a background task and false to index synchronously.
    Throws:
      `TdbException`

  - ### submitBatchJob

    public int submitBatchJob(TdbBatchJobType jobtype, String tform) throws TdbException
    Submit a LOAD and/or INDEX job on this database to TRIPsystem for background execution.

    If the TRIPsystem version is 8.4-6 or later and the function returns non-zero, it is possible to wait for a job completion result. Such completions are available via TdbJobResultSink objects, which can be registered with the current TdbSession instance to receive notifications on completed jobs.

    This method causes network I/O.

    Parameters:
      `jobtype` - The type of batch job to submit
      `tform` - Name of TFORM file to be loaded -- this is a server-specific file specification
    Returns:
      The ID of the submitted job if the TRIPsystem version is 8.4-6 or later, and zero otherwise
    Throws:
      `TdbException` - If job submission failed

      `TdbException`

  - ### reindex

    @Deprecated public void reindex() throws TdbException

    This method causes network I/O.

    Parameters:

    This method causes network I/O.

    Parameters:
      `key` - Foreign key field name
      `linkdb` - Master database name

  - ### diagnose

    public void diagnose(TdbErrorCheckSink sink, int phase) throws TdbException
    Check the database's primary data file (the BAF) for errors or conditions that might cause errors in the future. The phases involved in the diagnosis reflect the phases run by the command-line utility BAF DOCTOR.

    This method causes network I/O.

    Parameters:
      `sink` - A sink object that will collect results from the operation -- this must be provided by the caller and must not be null.
      `phase` - A value determining the phase or phases of diagnosis to execute: 0 - all phases; 1 - gross file integrity; 2 - simple internal file structure; 3 - (obsolete) cache-defeat file structure check; 4 - directory track validation; 5 - free list validation; 6 - rigorous data structure validation.
    Throws:
      `TdbException`

  - ### diagnose

    public void diagnose(TdbErrorCheckSink sink) throws TdbException
    Check the database's primary data file (the BAF) for errors or conditions that might cause errors in the future. This version of the method invokes all phases of diagnosis in one shot.

    This method causes network I/O.

    Parameters:
      `sink` - A sink object that will collect results from the operation -- this must be provided by the caller and must not be null.
    Throws:
      `TdbException`

  - ### compress

    public void compress(TdbCompressionContext ctx, boolean all) throws TdbException
    Requests a database compression operation, akin to the command line utility PACKIT. The operation can either be performed all at once, or using a call loop so as to allow the calling application to give the end user feedback on progress.

    This method causes network I/O.

    Parameters:
      `ctx` - Compression context. This context is used to tie together the compression operation and must be provided by the caller. If the application is using a call loop, i.e. calling this function iteratively until completed, the same context object must be provided for each iteration. Applications can test for the completion of the operation by testing the isComplete property of the context. Note that the new location of the database BAF must be provided using the NewName property of the context prior to the first call to this method. Calling applications can check the progress of the compression operation using the Progress and MaxRecs properties of the context following a successful invocation of the Compress method.
      `all` - If set true, the compression operation will take place in a single call. This might take considerable time, however, so the caller is encouraged to set this flag false and instead to place calls to this method within a loop that gives feedback to the user.
    Throws:
      `TdbException`
