hi,
im new to drools..im trying to create a project as follows. i have a class
called Monitor which monitors a folder and creates two lists called
fileOld( which is the list of filenames in that folder at time t1) and
fileNew(which is the list of filenames in that folder at time t2). i have
another class called FileData which contains two members fileOld and
fileNew (list of strings) with getters,setters and constructor. fileOld and
fileNew from Monitor Class are passed to FileData class.
i also have another class called Event which is as follows:
public class Event {
public static String name;
private File source;
private Date timeStamp;
public static List<Event> listOfEvents = new ArrayList<Event>();
public Event(String name, File source, Date timeStamp) {
this.name = name;
this.source = source;
this.timeStamp = timeStamp;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public File getSource() {
return source;
}
public void setSource(File source) {
this.source = source;
}
public Date getTimeStamp() {
return timeStamp;
}
public void setTimeStamp(Date timeStamp) {
this.timeStamp = timeStamp;
}
now i have to compare these two lists(fileOld and fileNew) in a rule file
and if they are not equal i have to create an event object for every file
added and deleted and put it in the List<Event> listOfEvents.
here is my rule file:
rrule "files are equal"
when
FileData( fileOld == fileNew)
then
System.out.println("files are equal");
end
rule "files not equal"
when
FileData($old : fileOld, $new : fileNew, fileOld != fileNew)
then
accumulate( $s : String( this not memberOf $old ) from $new, $plus :
collectList( $s ) )
accumulate( $t : String( this not memberOf $new ) from $old, $mins :
collectList( $t ) )
System.out.println("files added:" + $plus );
System.out.println( "files deleted:" + $mins );
end
how can i loop through each of the file added or deleted and create an
Event Class object for every file added and deleted and finally add all
the created objects to List<Event> listOfEvents..
Thanks.

The "accumulates" should not be in the "then" part of a rule (see my
previous email).
That rule gave you two lists, in the variables $plus and $mins, that you
can use in the consequence.
If you need to process each file separately, you may want to do
something like this:
rule "new file"
when
FileData($old : fileOld, $new : fileNew, fileOld != fileNew)
$newFile : String( this not memberOf $old ) from $new
then
// create new event for a new file : new Event(...)
// add to list : Event.listOfEvents.add(...)
end
You'll need another rule for the files that have been removed.
Notice that your Event class has no way to distinguish "added" from
"removed" files, you may want to
add a boolean or something there.

The problem here is even if multiple files are added, there is only one
event object created. i want to have like say if 3 new files are added, 3
event objects must be created, and all three event objects must be added to
List<Event> listOfEvents.
Thanks.

"from" will iterate for you, exactly like "accumulate" counted the
events.
If you need more details, please consult the documentation

i tried this :
rule "new file"
when
FileData($old : fileOld, $new : fileNew, fileOld != fileNew)
$newFile : String( this not memberOf $old ) from $new
then
event : Event("file added", filename, new Date()) from $plus
Event.listOfEvents.add(event);
event.display();
end
this gives the following error:

Will you please, please, PLEASE have a short look at the Drools
documentation, available just for the effort of reading it? This will
tell you that "accumulate" and "from" are constructs to be used on
the
left hand side of a rule and NOT on the right hand side, where (with
the exception of a few additional statements) everything is plain old
Java code.
Cheers

You should realize that the LHS ("when") and RHS ("then") are
different
and use different syntaxes.
The RHS is essentially java... you can't use ":" and "from".
Also.. "Event(..) from .." is a pattern - a filter that tries to match
existing objects asserted in the WM.
What you need there is to create a new Event.. just do it the way you
would in Java.
You will have to learn to read error messages, too.
What the error is trying to say, is that it interpreted the Event( .. )
statement as a method call,
which is of course undefined.
