Hello All
I have a requirement to run my workflow for XPand generator, from my own
java code.
I found some help on:
http://www.openarchitectureware.org/pub/documentation/4.3.1/ html/contents/workflow_reference.html
It suggests to use a code snippet as follows:
------------------------------------------------------------ ----------
String wfFile =
" C:/Users/Durga/workspace_TMF/org.xtext.samm.Edifice.generato r/src/workflow/EdificeGenerator.mwe ";
Map properties = new HashMap();
Map slotContents = new HashMap();
new WorkflowRunner().run(wfFile ,new NullProgressMonitor(), properties,
slotContents);
------------------------------------------------------------ ----------
But I don't know what the values in the HashMap should be!!
I mean which properties of the workflow.mwe file shall I set into which
hashmap contents.
properties.put(??);
slotContents.put(??);
I need 2 also somehow pass in a component object(entity) into the workflow
from the java code.And the workflow should then XPand a file for the
component attributes by:
------------------------------------------------------------ ---
<expand value="templates::Template::defn_ComplexDataType FOR
somecomponent_object(instead of model
file)/xml_file_representationofEntity"/>
------------------------------------------------------------ ---
Wud anyone pls suggest..
Thanks.
Durga

The first map (the properties) is a Map<String,String> containing all
properties you want to be replaced.
That is if you have something like
<myProp value="${foo}"/>
in your workflow file, you can pass the information what 'foo' means
using the properties map.
The other map (Map<String,Object> slotContens) allows you to put some
preinitialized information into a slot, so that components can use that
information.
This is how you solve your problem, just put an entry into the map,
mapping from a name to the actual object.
Example:
Map<String, Object> slotContents =
Collections.singletonMap("someComponent", myComponent);
can be used like this:
<expand value="templates::Template::defn_ComplexDataType FOR
somecomponent"/>
Cheers,
Sven
