Method Details

isDataPresent

public boolean isDataPresent()

Description copied from interface: ExecutionResult

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 ExecutionResult.getData() returns null. See : https://graphql.github.io/graphql-spec/June2018/#sec-Data

Specified by:

isDataPresent in interface ExecutionResult

Returns:

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

getErrors

public List<GraphQLError> getErrors()

Specified by:

getErrors in interface ExecutionResult

Returns:

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

getData

public <T> T getData()

Specified by:

getData in interface ExecutionResult

Type Parameters:

T - allows type coercion

Returns:

the data in the result or null if there is none

getExtensions

public Map<Object,Object> getExtensions()

Specified by:

getExtensions in interface ExecutionResult

Returns:

a map of extensions or null if there are none

toSpecification

public Map<String,Object> toSpecification()

Description copied from interface: ExecutionResult

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 : https://spec.graphql.org/October2021/#sec-Response-Format

Specified by:

toSpecification in interface ExecutionResult

Returns:

a map of the result that strictly follows the spec

errorsToSpec

private Object errorsToSpec(List<GraphQLError> errors)

toString

public String toString()

Overrides:

toString in class Object

newExecutionResult

public static ExecutionResultImpl.Builder newExecutionResult()
