Examples with Operation io.smallrye.graphql.schema.model.Operation used on opensource projects

Example 1 with Operation

use of io.smallrye.graphql.schema.model.Operation in project smallrye-graphql by smallrye.

the class OperationCreator method createOperation.

 * This creates a single operation.
 * It translate to one entry under a query / mutation in the schema or
 * one method in the Java class annotated with Query or Mutation
 *
 * @param methodInfo the java method
 * @param operationType the type of operation (Query / Mutation)
 * @param type
 * @return a Operation that defines this GraphQL Operation
