@PublicApi
public interface ExecutionResult

This simple value class represents the result of performing a graphql query.

Method Summary

Modifier and Type	Method and Description
<T> T	getData()
java.util.List<GraphQLError>	getErrors()
java.util.Map<java.lang.Object,java.lang.Object>	getExtensions()
boolean	isDataPresent() The graphql specification specifies: "If an error was encountered before execution begins, the data entry should not be present in the result.
java.util.Map<java.lang.String,java.lang.Object>	toSpecification() The graphql specification says that result of a call should be a map that follows certain rules on what items should be present.

Method Detail

getErrors

java.util.List<GraphQLError> getErrors()

Returns:

the errors that occurred during execution or empty list if there is none

getData

<T> T getData()

Type Parameters:

T - allows type coercion

Returns:

the data in the result or null if there is none

isDataPresent

boolean isDataPresent()

The graphql specification specifies: "If an error was encountered before execution begins, the data entry should not be present in the result. If an error was encountered during the execution that prevented a valid response, the data entry in the response should be null." This allows to distinguish between the cases where getData() returns null. See : https://graphql.github.io/graphql-spec/June2018/#sec-Data

Returns:

true if the entry "data" should be present in the result false otherwise

getExtensions

java.util.Map<java.lang.Object,java.lang.Object> getExtensions()

Returns:

a map of extensions or null if there are none

toSpecification

java.util.Map<java.lang.String,java.lang.Object> toSpecification()

The graphql specification says that result of a call should be a map that follows certain rules on what items should be present. Certain JSON serializers may or may interpret ExecutionResult to spec, so this method is provided to produce a map that strictly follows the specification. See : http://facebook.github.io/graphql/#sec-Response-Format

Returns:

a map of the result that strictly follows the spec
