[udig-devel] Edit Tool Plugin Implementation - Committing changes over b

[Victor San Kho Lin <victorlin21@xxxxxxxxx>]

Dear List,

Here is my situation.

I'm trying to implement curve edit tool.

Currently, my codes are heavily base on FreeHandTool and
FreeHandPolygonDrawBehivaour.. Since, my tools will draw Line/Curve
which will not be require any
closing path. I like to be end-up with open ends. One question here, when I determineShapeType() from current getEditLayer(), it always return polygon.. I don't understand where I left to configure this to be SimpleFeatureType LineString.  I used DrawType.LINE
at initActivators and I have to force ShapeType.LINE at implementing
behaviour.

And finally, I can use AbstractDrawCommand
for drawing line and curve and from Path/PathAdapter/GeneralPath  to EditUtils.appendPathToShape to adding
vertices feature points..

Now my main questions are: 

How can I commit these drawing/changes to backdrop Map layer?
I also want to write these drawing features/graphics to write on both features(vector) shapefiles layer and raster layer. How can I achieve that?
I don't know what is happening, but all my drawing features/graphics over shapefile  layer or raster layer could not save or commit changes..

Thanks and Regards,
Victor
