hi

i am working on mdsd. i am xpand for code generation and gmf for graph editor. i some how managed to generate code from gmf graph. i have a problem with code generation

my ecore file looks like this
TestCase -------main class contains
/ \
/ \
blocks links
/ | \
/ | \
start make end blocks

now in my xpand template

«DEFINE main FOR TestCase»
«FILE name +".mist"»

«EXPAND blk FOREACH blockRef SEPARATOR '#########################'» //this call all the blocks one by one

«ENDFILE»
«ENDDEFINE»

now i want to pass some parameters of start block to make block. how do i approach this?

Hello Ravi,

without knowing you actual metamodel (the following is unreadable to me)

Quote:

TestCase -------main class contains
/ \
/ \
blocks links
/ | \
/ | \
start make end blocks

it is hard to give concrete advice.

but

(1) you can pass additional parameters to templates
(2) you can naivigate the model up and down
(3) you can do sorting / filterting etc.

With some more information (metamodel/model) it can give more advice.

Hi,

you can pass parameters to Define blocks:

«DEFINE main FOR TestCase»
«FILE name +".mist"»

«EXPAND blk('#########################') FOREACH blockRef» 

«ENDFILE»
«ENDDEFINE»

«DEFINE blk(String param) FOR TestCase»
to something with param «param»
«ENDDEFINE»

Take a look at the Xpand documentation.
Xpand Documentation > I. Reference > Xpand / Xtend / Check Reference > Xpand > Define

Hi chris

thanks once again for replying

if i pass parameters like that in expand
i will have to define parameters for all the blocks unnecessarily.

plz find

my whole template code

------------------------------------------------------------

«IMPORT mist»
«DEFINE main FOR TestCase»
«FILE name +".mist"»

«REM»
«FOREACH linkRef AS lk»
«IF lk.sourceBlock.name=="start"»
hhhhhhh
«ENDIF»

«FOREACH blockRef AS blocks»
«blocks.name»
«ENDFOREACH»
«ENDREM»

«EXPAND blk FOREACH blockRef SEPARATOR '#########################'»
«ENDFILE»
«ENDDEFINE»

«DEFINE blk FOR block»
#could not find the matching block for this call
«ENDDEFINE»

«DEFINE blk FOR StartBlock»

now i want to use the dn1type and dn2type parameter of startblock in makecall block

Hi,

do you want something like this?

«DEFINE blk FOR MakeCallBlock»
«getTestCase().getStartBlock().Dn2type»
some make call code.........
«ENDDEFINE»

Then you have to import an Extension in your template

«IMPORT mist»
«EXTENSION template::Extensions»

The extensionfile
Extension.ext:

import mist;

TestCase getTestCase(block block):
	block.eContainer;

getStartBlock(TestCase tc):
	tc.blockRef.typeSelect(StartBlock).first();

Hi Darius Jockel

your solution worked super fine Very Happy

Thank you so much.

i have one more question. as you see my ecore model.

i have blocks and they are connected by links. when i generate code i am not able to generate code based on the flow.
it's based on the creation order of the elements in gmf

in my ecore
a link class has reference to source block and destination block. but blocks doesn't have any ref to links

any pointer as to how i can generate based on the flow
for instance
gmf editor :start--->make---->end

respective block should be called in xpand

i suspect i have to redesign my metamodel file with a linkRef!!! but how i can proceed ?

or should i go about with something like extension

Regards
Ravi

Hi,

same as before: use xtend to navigate on the model

import mist;

List[block] getSuccessors(block in) :
	((TestCase)in.eContainer).linkRef.select(e|e.sourceBlock == in).destinationBlock;

maybe you should start with the startblock(s) in the testcase

«DEFINE main FOR TestCase»
...
«EXPAND handleStartBlock FOREACH blockRef.typeSelect(StartBlock)»
...
«ENDDEFINE»
