Client |
alias(Map<String,String> aliases)
Creates a
Client that supplies the specified set of aliases, thus allowing the user to re-name
one or more globally defined Graph or TraversalSource server bindings for the context of
the created Client . |
Client |
alias(String graphOrTraversalSource)
Create a new
Client that aliases the specified Graph or TraversalSource name on the
server to a variable called "g" for the context of the requests made through that Client . |
protected org.apache.tinkerpop.gremlin.driver.Connection |
chooseConnection(RequestMessage msg)
Uses a
LoadBalancingStrategy to choose the best Host and then selects the best connection
from that host's connection pool. |
CompletableFuture<Void> |
closeAsync()
Closes all the connection pools on all hosts.
|
protected void |
initializeImplementation()
Initializes the connection pools on all hosts.

Deprecated.

rebind(String graphOrTraversalSource)
Deprecated.
|
ResultSet |
submit(String gremlin,
String graphOrTraversalSource)
Submits a Gremlin script to the server and returns a
ResultSet once the write of the request is
complete. |
ResultSet |
submit(String gremlin,
String graphOrTraversalSource,
Map<String,Object> parameters)
Submits a Gremlin script and bound parameters to the server and returns a
ResultSet once the write of
the request is complete. |
CompletableFuture<ResultSet> |
submitAsync(String gremlin,
Map<String,String> aliases,
Map<String,Object> parameters)
The asynchronous version of
Client.submit(String, Map) } where the returned future will complete when the
write of the request completes. |
CompletableFuture<ResultSet> |
submitAsync(String gremlin,
String graphOrTraversalSource,
Map<String,Object> parameters)
The asynchronous version of
