Porting example
Step 1 Choose an object to port
I randomly picked the Filter object e.g. XFilter in the helperapi ( of course you also want to make sure this object isn't already implemented in oovbaapi ). Browse the helperapi code to fine where XFilter is implemented. It's implemented by FilterImpl.java and it expects to be initialised by an XAutoFilter implementation object AutoFilterImpl
so already we need to think about providing an implementation not only for XFilter but also for XAutoFilter
looking at XAutoFilter.idl we see that there is a Filters() attribute/method that returns a Collection of Filters, so additionally I now realise I also need an implementation of the XFilters object. The XAutoFilter implementation is the key object that the others are accessed/provided from. After some searching through the source code I find this is an attribute of the SheetImpl object
so, to summarize, after initially choosing one object to have a crack at porting, I find in fact I actually need to provide implementations for the following interfaces
- XFilter
- XAutoFilter
- XFilters
and also I need to add a new attribute to return an XAutoFilter implementation
Step 2 Port the idl files
It's worth taking a look at the idl section in the porting notes and examples of the ported idl files
also modifications to existing files
- makefile.mk add new idl file
- XWorksheet.idl add new AutoFilter attribute
