public PackedDBHandle(String contentType)
               throws IOException

Constructs a temporary packed database handle.

Parameters:

contentType - user defined content type.

Throws:

IOException

Method Details

save

public void save(String comment,
 DBChangeSet changeSet,
 TaskMonitor monitor)
          throws IOException,
CancelledException

Description copied from class: DBHandle

Save this database to a new version.

Overrides:

save in class DBHandle

Parameters:

comment - if version history is maintained, this comment will be associated with the new version.

changeSet - an optional database-backed change set which reflects changes made since the last version.

monitor - progress monitor

Throws:

IOException - thrown if an IO error occurs.

CancelledException - if task monitor cancelled operation.

save

public void save(TaskMonitor monitor)
          throws IOException,
CancelledException

Saves the open database to the corresponding PackedDatabase file.

Parameters:

monitor -

Throws:

IOException

CancelledException

saveAs

protected void saveAs(BufferFile outFile,
 Long newDatabaseId,
 boolean associateWithNewFile,
 TaskMonitor monitor)
               throws IOException,
CancelledException

Description copied from class: DBHandle

Save the database to the specified buffer file and a newDatabaseId. Open handle will always be associated with the new file. NOTE: This method is intended for use in transforming one database to match another existing database.

Overrides:

saveAs in class DBHandle

Parameters:

outFile - buffer file open for writing

newDatabaseId - database ID to be forced for new database or null to generate new database ID

associateWithNewFile - if true the outFile will be associated with this DBHandle as the current source file, if false no change will be made to this DBHandle's state and the outFile will be written and set as read-only. The caller is responsbile for disposing the outFile if this parameter is false.

monitor - progress monitor

Throws:

IOException - if IO error occurs

CancelledException - if monitor cancels operation

saveAs

public void saveAs(BufferFile outFile,
 boolean associateWithNewFile,
 TaskMonitor monitor)
            throws IOException,
CancelledException

Description copied from class: DBHandle

Save the database to the specified buffer file.

Overrides:

saveAs in class DBHandle

Parameters:

outFile - buffer file open for writing

associateWithNewFile - if true the outFile will be associated with this DBHandle as the current source file, if false no change will be made to this DBHandle's state and the outFile will be written and set as read-only. The caller is responsbile for disposing the outFile if this parameter is false.

monitor - progress monitor

public void close()

Description copied from class: DBHandle

Close the database and dispose of the underlying buffer manager. Any existing recovery data will be discarded.

Overrides:

close in class DBHandle

public PackedDatabase saveAs(String itemName,
 File dir,
 String packedFileName,
 TaskMonitor monitor)
                      throws IOException,
DuplicateFileException,
CancelledException

Save open database to a new packed database. If another PackedDatabase was associated with this handle prior to this invocation it should be disposed to that the underlying database resources can be cleaned-up.

Parameters:

itemName -

dir -

packedFileName -

monitor -

Returns:

new packed Database object now associated with this handle.

Throws:

CancelledException - if task monitor cancelled operation.

IOException

DuplicateFileException
