Creating vertices and (heavyweight) edges in a transaction

[Lithl]

I am trying to create an extension method which, given a model object, will create vertices and edges between those vertices so that the model is accurately represented in the graph. For example, the models:

Person
    string FirstName
    string LastName
    Address Residence
    Address Shipping

Dependent : Person
    int Relationship

Address
    string AddressLine1
    string AddressLine2
    Person Resident

Creating a record with a Dependent object would be, essentially:

create vertex Dependent content {...}
create vertex Address content {...}
create vertex Address content {...}
create edge ResidenceAddress from ... to ...
create edge ShippingAddress from ... to ...

However, when I use OTransaction#Add to create these records, my heavyweight edges are not connected to my vertices. All of my vertices are created with their properties set correctly, and all of my edges are created wit their properties set correctly (including out and in), but the vertices can't see their edges.

I can apparently replicate this same behavior within the OrientDB studio using insert into ... instead of create edge ...

According to RobinG in a response to my SO question about this, the OTransaction class is incomplete, so I began attempting to add to the library so that I could get heavyweight edges working with transactions properly. However, my understanding of the binary interface is limited, and I've run into a wall.

Hi @Lithl,

I looked to OTransaction class and is complete and do work.
Added example how to create heavy-edges with OTransaction.

Thanks, GoorMoon, I seem to have it working.

If you want to create an answer on my SO question, I'll happily mark it as accepted.
