BeanShell-Filter

Diese Seite enthält einige Beispiele für die Verwendung von BeanShell-Filtern. Der angegebene Code muss jeweils in das Textfeld einer BeanShell-Filterkomponente kopiert werden.

Sendungen mit Bildern

import devplugin.beanshell.BeanShellProgramFilterIf; 
import devplugin.Program; 
import devplugin.ProgramFieldType; 

accept(Program p) { 
  if(p.getBinaryField(ProgramFieldType.PICTURE_TYPE) != null) 
    return true; 
   
  return false; 
} 

return (BeanShellProgramFilterIf) this;

Temporär alle Premiere-Sendungen ausblenden

import devplugin.beanshell.BeanShellProgramFilterIf; 
import devplugin.Program; 

accept(Program p) { 
    String s=p.getChannel().toString(); 
    return (-1==s.indexOf("Premiere"));  
}

return (BeanShellProgramFilterIf) this;

Sendungen, bei denen der Regisseur auch Schauspieler ist

import devplugin.beanshell.BeanShellProgramFilterIf;
import devplugin.Program;
import devplugin.ProgramFieldType;

accept(Program p) {
  String director = p.getTextField(ProgramFieldType.DIRECTOR_TYPE);
  String actors = p.getTextField(ProgramFieldType.ACTOR_LIST_TYPE);
  if (director != null && actors != null) {
    if (actors.indexOf(director) >= 0) {
      return true;
    }
  }
  return false;
}

return (BeanShellProgramFilterIf) this;

Dynamischer BeanShell-Filter als CSV-File-Interface

// Beanshell-Filter: CSV file interface
