tinkerpop3 - Different behavior between neo4j-gremlin-bolt , Tinkergraph and Neo4j-gremlin -


i seeing different behavior between tinkergraph , neo4j-gremlin neo4j-gremlin-bolt neo4j implementation of tinkerpop3, in bit of code:

// different tinkerpop impls graph graph = new neo4jgraph(driver, vertexidprovider, edgeidprovider); // graph graph = neo4jgraph.open("c:\\tmp\neo"); // graph graph = tinkergraph.open();  graphtraversalsource g = graph.traversal();  string label = "person";  (int = 0; < 10; i++) {   system.out.println("before " + +g.v().tolist().size());   graph.addvertex(label);   system.out.println("after " + +g.v().tolist().size()); }  // if graph transactional  graph.tx().commit();

what expected vertex count increments 1 10 see tinkergraph , neo4j-gremlin. see neo4j-gremlin-bolt count 1 (after first addvertex). after commit, 10 instances appear in neo4j db (as expected). running second time, count 11 (after first addvertex) , 20 instances appear after commit.

the way have gotten work expected neo4j-gremlin-bolt commit() , close() graph after every addvertex, doesn't seem right.

this seems fundamental behavior, assume missing obvious.

neo4j-gremlin-bolt - v0.2.18

tinkergraph-gremlin - v3.2.4

neo4j-gremlin - v3.2.4

turns out bug in neo4j-gremlin-bolt's handing of transient objects: https://github.com/steelbridgelabs/neo4j-gremlin-bolt/issues/52

fix expected shortly.

inversion of control - Autofac named registration constructor injection -

does autofac support specifying registration name in components' constructors? example: ninject's namedattribute . you need use autofac.extras.attributed package on top achieve this so let's have 1 interface , 2 classes: public interface ihello { string sayhello(); } public class englishhello : ihello { public string sayhello() { return "hello"; } } public class frenchhello : ihello { public string sayhello() { return "bonjour"; } } then have consumer class, in want select instance injected: public class helloconsumer { private readonly ihello helloservice; public helloconsumer([withkey("en")] ihello helloservice) { if (helloservice == null) { throw new argumentnullexception("helloservice"); } this.helloservice = helloservice; } public string sayhello() { return this.helloservice.sayhello()...

verilog - Systemverilog dynamic casting issues -

i've code snippet following in testbench function void write_to_port( my_data_type_base data ); my_data_type_extended data_ext; if(!$cast(data_ext, data)); `uvm_error(get_type_name(), "failed cast"); `uvm_info(get_name(), $psprintf("data_ext :\n%s", data_ext.sprint()), uvm_medium) // write data_ext out port.... endfunction when run it, i'm getting uvm_error "failed cast." i'm not quire sure why $cast not returning 1. can see, i'm printing out extended class data item after casting uvm_info. can see it's being cast properly. if don't use $cast if condition, don't runtime error. isn't coding practice use if dynamic cast check if $cast returning 1 ? what might reason behind cast not returning 1 in above case? i think semicolon on line 'if' not belong? i think consumes if statement, , uvm_error executes regardless of how if evaluates: if(!$cast(data_ext, data)); <- no semico...

ios - Change Storyboard View using Seague -

i have following code checks connection server, , depending on want change views if no connection found. nsstring *connect = [nsstring stringwithcontentsofurl:[nsurl urlwithstring:@"http://myserver.com"] encoding:nsutf8stringencoding error:nil]; if (connect == null) { [self performseguewithidentifier:@"network_failure" sender:self]; } else { // other code here } my problem not change views. have added storyboard segue between 2 views identifier of network_failure . not have navigation controller or that, problem? thanks help! no not problem. first of all, in objectivec exists nil object oriented null . must use that. so: if(connect == nil) or better: if(!connect) so due fact nil not same of null , probably code does't enter in if scope . you have been able discover breakpoint. anyway: be sure set trigger segue (line) 2 view controller , , name network_failure (that not best name. should instead view1toview2 ) as, m...
