Description

Class Summary

DatabaseApplicationProperties	This class provides common support to applications requiring properties related to database services.
DatabaseInformationModel	The DatabaseInformationModel class is an abstract class that contains the core functionality for storing, accessing and maintaining a persistent representation of selected attributes of composite objects.
DatabaseMediaImporter
DatabaseTreeBrowser	The DatabaseTreeBrowser class implements a Swing graphical user interface to browse the contents of DatabaseInformationModel.
DatabaseTreeModel	The DatabaseTreeModel class implements a TreeModel to abstract the contents of a database as a tree in order to provide support for a DatabaseTreeBrowser.
DatabaseTreeRecord	Instances of the DatabaseTreeRecord class represent nodes in a tree of the DatabaseTreeModel class, which in turn is used by the DatabaseTreeBrowser class.
DateTimeRangeMatch
DeleteFromDatabase	This class provides methods for removing entries from a database, all its children and any associated files that were copied into the database (rather than referenced).
DicomDatabaseInformationModel	The DicomDatabaseInformationModel class is an abstract class that specializes DatabaseInformationModel by adding methods specific to a typical DICOM composite object information model.
DicomDictionaryForMinimalPatientStudySeriesInstanceModel	The DicomDictionaryForMinimalPatientStudySeriesInstanceModel class supports a simple DICOM Patient/Study/Series/Concatenation/Instance model.
DicomDictionaryForPatientStudySeriesConcatenationInstanceModel	The DicomDictionaryForPatientStudySeriesConcatenationInstanceModel class supports a simple DICOM Patient/Study/Series/Concatenation/Instance model.
DicomDictionaryForStudySeriesInstanceModel	The DicomDictionaryForStudySeriesInstanceModel class supports a minimal DICOM Study/Series/Instance model.
MapTableBrowser	The MapTableBrowser class extends a JTable to browse a list of attributes and their values as a single row table with columns headed by the attribute descriptions (if supplied) or their names.
MapTableModel	The MapTableModel class extends a AbstractTableModel to abstract the contents of a database as a tree in order to provide support for a MapTableBrowser.
MinimalPatientStudySeriesInstanceModel	The MinimalPatientStudySeriesInstanceModel class supports a minimal DICOM Patient/Study/Series/Instance model.
PatientStudySeriesConcatenationInstanceModel	The PatientStudySeriesConcatenationInstanceModel class supports a simple DICOM Patient/Study/Series/Concatenation/Instance model.
RebuildDatabaseFromInstanceFiles	This class allows the reconstruction of a database from the stored instance files, such as when the database schema model has been changed.
StudySeriesInstanceModel	The StudySeriesInstanceModel class supports a minimal DICOM Study/Series/Instance model.
StudySeriesInstanceSelectiveMatchModel	The StudySeriesInstanceSelectiveMatchModel class supports a minimal DICOM Study/Series/Instance model.

Package com.pixelmed.database Description

Abstracts any underlying database support for applications using the DICOM toolkit and needing access to persistent storage of entities in the DICOM information model.

The primary class of this package is the abstract DatabaseInformationModel. It provides general facilities for connecting to the underlying database, creating tables, inserting, modifying, deleting and selecting records. In addition it provdes abstract methods for describing the types of entities mapped to records in tables and their relationships.

Concrete implementations of the DatabaseInformationModel are provided for commonly used models, including the PatientStudySeriesConcatenationInstanceModel and the StudySeriesInstanceModel.

The models make use of specialized forms of the generic com.pixelmed.dicom.DicomDictionary in order to make sure particular DICOM attributes are mapped to the correct information entity (i.e. database table) appropriate to the model in use.

Tree and table browsers and models are provided that may be used to form the basis of application specific browsers.

The following is a simple example of how a database is created, populated by one or more DICOM files, and a browser created:

public static void main(String arg[]) {
        try {
                final DatabaseInformationModel d = new PatientStudySeriesConcatenationInstanceModel("test");
                for (int j=0; j<arg.length; ++j) {
                        String fileName = arg[j];
                        DicomInputStream dfi = new DicomInputStream(new BufferedInputStream(new FileInputStream(fileName)));
                        AttributeList list = new AttributeList();
                        list.read(dfi);
                        dfi.close();
                        d.insertObject(list,fileName);
                }
                final JFrame frame = new JFrame();
                frame.setSize(400,800);
                frame.addWindowListener(new WindowAdapter() {
                        public void windowClosing(WindowEvent e) {
                                frame.dispose();
                                d.close();
                                System.exit(0);
                        }
                });
                DatabaseTreeBrowser tree = new DatabaseTreeBrowser(d,frame);
                frame.show(); 
        } catch (Exception e) {
                System.out.println(e);
                e.printStackTrace();
                System.exit(0);
        }
}
