I am trying to make a custom ECL command to extract a data from table in order to make my custom assertions on that data. I want to use the result of:
get-table | ...
But when I read an object from process.getInput().read(), I get an object of the class ControlHandlerImpl and I don't know how to handle this further. Do you have some examples using the input pipe?
When Q7 passes controls around (like in
'get-view "..." | get-tree), it does not operate on widgets, instead, a special descriptor EMF objects used. There is a special command get-object, which allows to extract an actual widget object and pass it to other command.
Therefore, while writing custom command, it is better to declare an input parameter in EMF model as EJavaObject and then use it like this:
get-view "Package Explorer" | get-tree | get-object | my-custom-tree-command
A good starting point to look at might be an invoke command, which takes a Java object from input and invokes methods via reflection. It's model is described like this:
An implementation of invoke command can be found at Github ECL repo – InvokeService.java.
