generally you can use graphDatabaseContext.createEntityFromStoredType(node)
or graphDatabaseContext.createEntityFromState(node, type)
But normally you wouldn't do that but rather pass your traversal description to
a repository or your entity.
GraphRepository<Product> repo =
directGraphRepositoryFactory.createGraphRepository(Product.class) // or declare
the repository via interfaces and add <datagraph:repository ...> to your config.
Iterable<Product> products =
repo.findAllByTraversal(product.getPersistentState(), traversalDescription);
from your entity you can do:
@GraphTraversal(builder = ProductsTraversalBuilder.class)
Iterable<Product> products;
or use the method on the entity:
Iterable<Product> products = product.findAllByTraversal(Product.class,
traversalDesc);
