Returning a set

There is another method that returns java.util.Collection<Variable>

I *think* that all of them are returning classes of type org.prorefactor.core.JPNode

But, I haven't a clue as to how I would define an ABL class of the appropriate type to receive these, nor how I would iterate through them once I did.  I am finding it hard to get much of a clue from the .NET docs because these are Java types.

I would only guess that if the package was converted to a .NET DLL that the classes returned from it are .NET (or at least .NET wrappers) even though the names suggest they are Java classes.  So yes, define a variable of whatever type it says the method returns and put it on the left side of the left side of the assignment.  For generic classes, with angle brackets in the name, make sure the type name is in quotes when you define it.

Of course make sure that this DLL is in your assemblies .xml file and that the DLL is in the same directory as the .xml file.

Laura is right Thomas, you should forget about the Java classes there and just use the DLL... IKVM took care of 'translation' so just check out the methods available in the assembly by using the class browser inside PSDOE.

Ah, and check-out Mike's include files for doing for-each on .net collections ;)

Yes, it is clear that iKVM has provided .NET classes with the names of the Java collection classes so presumably I can define a variable of that type and use it for the result.  It is just figuring out how to iterate through it.  I will see if I can find something from Mike.

Thanks!!!!

Looks like this is going to take a bit more research since the class browser shows no internals for IKVM.OpenJDK.Core where I presume these classes live.

So, I have gotten to:

define variable molBufferList as class java.util.Set no-undo.
define variable mobIterator as class java.util.Iterator no-undo.
define variable mobTableBuffer as class TableBuffer no-undo.

molBufferList = ipobParseUnit:getRootScope():getBufferSet().
mobIterator = molBufferList:iterator().

do while mobIterator:hasNext():
  mobTableBuffer = cast( mobIterator:next(), TableBuffer ).

But, this is giving me:

Error: Invalid cast from java.util.HashMap+Entry to org.prorefactor.treeparser.TableBuffer
So, I seem to get the java.util.Set correctly, but presumably its contents are not supersets of TableBuffer.

So, it is not clear to me what those Set entries are.

How about:

mobTableBuffer = CAST( mobIterator:next():getValue(), TableBuffer ).

This works:

define variable molBufferList as class java.util.ArrayList no-undo.
define variable mobIterator as class java.util.Iterator no-undo.
define variable mobSymbol as class Symbol no-undo.
define variable mobTableBuffer as class TableBuffer no-undo.
define variable mobTable as class org.prorefactor.core.schema.Table no-undo.

molBufferList = ipobParseUnit:getRootScope():getAllSymbolsDeep( ).
mobIterator = molBufferList:iterator().

do while mobIterator:hasNext():
mobSymbol = cast( mobIterator:next(), Symbol ).

if NodeTypes:getTypeName(mobSymbol:getProgressType()) <> "BUFFER" then next.

mobTableBuffer = cast( mobSymbol, TableBuffer ).
mobTable = mobTableBuffer:getTable().

This works, but I can find no expression to use as an argument to getAllSymbolsDeep() that will return only buffers.

mobSymbol:fullName() is getting me the qualified name including the database or not qualified if a temp-table.
mobTable:getName() gets me the name, not qualified, of the actual table.
