Yes it does. I want to use java only to import data into orientdb so i
changed my code:
@Override
public void openGraph(boolean transaction) {
if(transaction) {
this.graph = new OrientGraph(this.pathToOrientDB, "admin", "admin");
} else {
this.graph = new OrientGraphNoTx(this.pathToOrientDB, "admin",
"admin");
}
}
I now simply make to iterations over my file. first iteration i create all
my classes using OrientGraphNoTx. Second iteration i do the rest.
Thanks for the hint.
