Example 29 with ExecutionResult

use of graphql.ExecutionResult in project graphql-java by graphql-java.

 * <p>
 * Graphql fragments mean that for any give logical field can have one or more {@link Field} values associated with it
 * in the query, hence the fieldList.  However the first entry is representative of the field for most purposes.
 *
 * @param executionContext contains the top level execution parameters
 * @param parameters       contains the parameters holding the fields to be executed and source object
 *
 * @return an {@link ExecutionResult}
