All Implemented Interfaces:

IPersistentObject, ISelectable

public class Messwert
extends PersistentObject

Here we define our own data type for our "measurements"-Plugin. The Type is derived from ch.elexis.data.PersistentObject, and thereby the mananagement of the object persistence is completely delegated to elexis. The Method getSetup() creates (if necessary) a new table for our type. Some methods are required for every class derived from PersistentObject to work properly. Those methods are herafter marked with -required- Hier wird ein eigener Datentyp für unser "Messwerte"-Plugin definiert. Der Datentyp wird von PersistentObject abgeleitet, was das Persistenzmanagement an Elexis delegiert. In der Methode getSetup() wird wenn nötig eine neue Tabelle zur Speicherung der Daten dieses Datentyps erstellt. Einige Methoden _müssen_ vorhanden sein, damit eine von PersistentObject abgeleitetes Klasse korrekt funktioniert. Diese sind im Folgenden mit -Zwingend- markiert.

Constructor Detail

Messwert

public Messwert(Patient pat,
                java.lang.String name,
                java.lang.String date,
                java.util.Map<java.lang.Object,java.lang.Object> bf)

This is the only public constructor. The parameterless constructor should never be used, as it does not create the object in the database. The constructor with a single string parameter should never be called from outside the class itself. Dies ist der einzige öffentliche Konstruktor. Der parameterlose Konstruktor sollte nie verwendet werden, da er das Objekt nicht persistiert, und der Konstruktor mit einem einzelnen String Element sollte nie direkt aufgerufen werden (s. dort)

Parameters:

pat - Der Patient, dem dieser Messwert zugeordnet werden soll

name - Name des Messwerts

date - Datum des Messwerts

bf - Der Messwert in beliebige komplexer Form, wird als Black Box betrachtet

Method Detail

getDate

public java.lang.String getDate()

getLabel

public java.lang.String getLabel()

a concise, human readable indentification for the measurement. Subclasses should always override this, because the abse implementation of PersistentObject gives only an empty string. Eine kurze menschenlesbare Identifikation für den Messwert liefern. Sollte überschrieben werden; die Standardimplementation von PersistentObject liefert einfach einen Leerstring zurück.

Specified by:

getLabel in interface IPersistentObject

Specified by:

getLabel in class PersistentObject

getResult

public java.lang.String getResult(java.lang.String field)

getSetup

public static Messwert getSetup()

Here are configuration details read. If reading fails, the method assumes, that the table does not exist yet an creates it. Hier werden Konfigurationseinzelheiten eingelesen. Wenn das Lesen fehlschlägt, nimmt die Methode an, dass die Tabelle noch nicht existiert und legt sie neu an.

Returns:

load

public static Messwert load(java.lang.String id)

-required- This is the standard method to construct a PersistentObject from its representation in the database. For semantic reasons we intenionally do not use the "new" constructor for that purpose. "New" should only be used to create really "new" Objects and not to load existing objects from the database. Internally, however, load simply calls new(String). The static method load(String) must exist in every sublclass of PersistentObject, but it can always be written just exacly as here. The method needs not to guarantee that the returned object exists. It can, if desired, return a null value to indicate a inexistent object. Here we return just whatever the superclass gives us. -Zwingend- Dies ist die Standardmethode zum Konstruieren eines PersistentObjects aus der Datenbank. Aus semantischen Gründen wurde hierfür bewusst nicht der "new" Konstruktor verwendet. "New" bleibt gegen aussen für die Erstellung "neuer" Objekte reserviert. Intern allerdings ruft load einfach new(String) auf. Das kann immer exakt so formuliert werden.

Parameters:

id - ID des zu ladenden Objektes

Returns:

Das Objekt (kann auch null oder inexistent sein)
