Language

- com.faunadb.client.query.Language

public final class Language
extends java.lang.Object

The Language class contains static constructors for the FaunaDB Query Language expressions. This class is intended to be statically imported into your code with: import static com.faunadb.client.query.Language.*;

Each method in the Language class constructs a new Expr instance. No computation is executed until the expression is evaluated by the FaunaDB server.

Example:


   // Creates a new expression that, once executed, it will create a new instance
   // of the user collection with an username and password fields.
   Expr createUserExpr = Create(Collection("user"), Obj("data", Obj(
     "username", Value("bob"),
     "password", Value("abc123"),
   )));

   // Executes the expression created above and get its result.
   Value result = client.query(createUserExpr).get();

 // the values can be referenced to by the expression provided
 // using their given names.
 Map<String, Expr> bindings = new HashMap<>();
 bindings.add("name", Value("Bob"));
 bindings.add("age", Value(53));

 client.query(
