ODB 1.5.1
I think i found the problem, on graph init I do initialization of classes
for Edges and Vertexes, and such classes has intersections like USER, so as
I right understand it is not possible create classes with same name for
Edges and Vertexes?
public enum Relationship {
USER, TAGS, PROPERTIES,
FOLDERVERSION, ITEMVERSION, //used for versioned relations
FOLDER, ITEM, // used to store tree structure
THREAD
};
public enum ItemType {
ROOT, USER, FOLDER, BLOB, TAG, PROPERTY
};
private void initGraph(){
OGlobalConfiguration.CACHE_LEVEL1_ENABLED.setValue(false);
OGlobalConfiguration.DB_USE_DISTRIBUTED_VERSION.setValue(false);
OGlobalConfiguration.NON_TX_RECORD_UPDATE_SYNCH.setValue(true); //Executes
a synch against the file-system at every record operation. This slows down
records updates but guarantee reliability on unreliable drives
OGlobalConfiguration.TX_LOG_SYNCH.setValue(true); //Executes a synch
against the file-system for each log entry. This slows down transactions
but guarantee transaction reliability on non-reliable drives
graph = new OrientGraph(location);
graph.getRawGraph().commit();
for (ItemType type : ItemType.values()) {
try {
graph.createVertexType(type.toString().toLowerCase(Locale.ENGLISH
)).setSuperClass(graph.getVertexBaseType());
} catch (OSchemaException e) {
logger.debug("Vertex class "+type.toString()+" already exists in current
database", e);
}
};
for (Relationship type : Relationship.values()) {
try {
graph.createEdgeType(type.toString().toLowerCase(Locale.ENGLISH
)).setSuperClass(graph.getEdgeBaseType());
} catch (OSchemaException e) {
logger.debug("Edge class "+type.toString()+" already exists in current
database", e);
}
};
}
