BeanShell - Textdatei auslesen

[ds10]

Der Vorteil mit Entwicklungsumgebung ist, dass du das einmal einrichtest und dann immer bei Bedarf direkt etwas ändern kannst.
Es hört sich vielleicht zu Anfang schwierig an, aber das ist viel leichter als man denkt.

[Sheldon2012]

Das ist schon klar. Ich kann die Umgebung ja dann auch bei Gelegenheit mal einrichten.
in dem aktuellen Fall wäre es aber lieb, wenn Du das übernhemen könntest. Geht das?

[ds10]

Ja, kann ich machen, wenn ich die fehlenden Dateien noch bekomme.

[Sheldon2012]

Super! Danke!

Hier sind die Property-Files.

csvfilefiltercomponent.properties

Code: Alles auswählen

FilterFilterComponent.compName = CSV Filter
FilterFilterComponent.description = Allows to build filter components reading filter information from a CSV file.
FilterFilterComponent.name = CSVFileFilterComponent
FilterFilterComponent.settings.info = Please provide the CSV file path:

csvfilefiltercomponent_de.properties

Code: Alles auswählen

FilterFilterComponent.compName = CSV-Datei
FilterFilterComponent.description = Ermöglicht die Erstellung von Filterkomponenten deren Filterinformationen aus einer CSV-Datei gelesen werden.
FilterFilterComponent.name = CSV-Datei-Filterkomponente
FilterFilterComponent.settings.info = Bitte geben Sie den Pfad zur CSV-Datei an:

[Sheldon2012]

Bitte sende mir den korrigierten Code, falls da noch Bugs drin sind.

[ds10]

Der Quellcode ist in der Plugin-Datei enthalten.

CSVFileFilterComponent.jar

[Sheldon2012]

Danke!
Das JAR kopiere ich dann in das Plugin-Verzeichnis! Richtig?
Ich mache dann mal einen Performance-Test.

[ds10]

Ja, oder du ziehst die Datei in das TV-Browser Fenster, dann wird die Installation angeboten.

[Sheldon2012]

Oh jeh! Wenn ich für den Filter mit der neuen Komponente ein Filter-Info Icon anlege, erhalte ich vom Filter-Info-Icon Plugin eine Exception

Code: Alles auswählen

Das Plugin "Filter-Info-Icons" hat einen Fehler verursacht. Soll es deaktiviert werden?

Die exception ist zu lang.

[ds10]

Das zeigt nur, wie viel einfacher es wäre, wenn du eine Entwicklungsumgebung hättest:

CSVFileFilterComponent.jar

(7.85 KiB) 108-mal heruntergeladen

[Sheldon2012]

Hurra, Jetzt sind die Exceptions weg! Danke!
Und das Plugin funktioniert sogar! Kaum zu glauben!

Prinzipiell hast Du ja recht! Aber wenn die Fehler, so wie jetzt, aus einer ganz anderen Ecke kommen, benötige ich mit dem aktuellen Wissensstand bzgl. des Quellcodes bis Weihnachten, um den Fehler zu finden. Wann soll ich denn dann noch Geschenke kaufen?

Aberjetzt habe ich ja ein aktuelles Beispiel, von dem ich weiss, das es funktioniert, an dem ich das ganze mal durchspielen kann.

[ds10]

Aber wenn die Fehler, so wie jetzt, aus einer ganz anderen Ecke kommen, benötige ich mit dem aktuellen Wissensstand bzgl. des Quellcodes bis Weihnachten, um den Fehler zu finden.

Das denke ich nicht. Java-Fehlermeldungen sind sehr spezfisch:

Code: Alles auswählen

java.lang.NullPointerException
  at csvfilefiltercomponent.CSVFileFilterComp.prepareForComparison(CSVFileFilterComp.java:195)

D.h. in Zeile 195 in CSVFileFilterComp.java trat eine NullPointerException auf. Eine NullPointerException bedeutet, es wurde auf null oder eine Variable die null enthält zugegriffen, als wenn sie nicht null wäre, Beispiel:

Code: Alles auswählen

...
23 String name;
24
25 if(name.length() > 0) {
26   System.out.println(name);
27 }
...

wird eine NullPointerException in Zeile 25 anzeigen, denn die Variable name ist nicht mit einem String initialisiert worden und enthält folglich null. Den Fehler würde man dann beispielsweise so beheben:

Code: Alles auswählen

...
23 String name = "";
24
25 if(name.length() > 0) {
26   System.out.println(name);
27 }
...

[Sheldon2012]

Die Performance ist jedoch katastrophal. Das habe ich befürchtet.
Bei 10.000 Einträgen in der Datei geht im TV-Browser fast nichts mehr.
Das ist natürlich irgendwo klar, wenn permanent abgefragt wird.
Womit wir wieder bei der Option wären.
