method flow documentation (sequence diagrams etc) [message #203953] Thu, 30 November 2006 05:34

Hi,

when I want to modify BIRT behaviour using javascript,
I often find that I don't know the flow of BIRT methods.
I looked at BIRT ROM, javadoc and they are not sufficient.

For example I want to update legend entry in pie chart
based on category value and series value. This links is
usefull as I can find here list of methods including arguments:
http://help.eclipse.org/help31/topic/org.eclipse.birt.doc/ch art/api/org/eclipse/birt/chart/script/IChartEventHandler.htm l
Unfortunatelly javadoc is short and usually summarizes
method names and man must guess the purpose :-(
Now I want to choose which method to override. Is it
beforeDrawLegendEntry()? Or shall I modify displayValue
directly in DataSet within afterDataSetFilled() call?
It would helpful to see the sequence diagram.

Is there somewhere some high-level architecture picture
of BIRT? I'd like to see the process of report generation,
which methods are called and in which order. When are filters
applied? Etc.

Thanks in advance

Leos
