PHP Class GraphQL\Executor\Executor

"Definitions" are the generic name for top-level statements in the document. Examples of this include: 1) Operations (such as a query) 2) Fragments "Operations" are a generic name for requests in the document. Examples of this include: 1) query, 2) mutation "Selections" are the statements that can appear legally and at single level of the query. These include: 1) field references e.g "a" 2) fragment "spreads" e.g. "...c" 3) inline fragment "spreads" e.g. "...on Type { a }" Exibir arquivo Open project: webonyx/graphql-php Class Usage Examples

Public Methods

Method	Description
completeValueWithLocatedError ( ExecutionContext $exeContext, Type $returnType, $fieldNodes, ResolveInfo $info, $path, $result ) : array | null | GraphQL\Executor\Promise\Promise	This is a small wrapper around completeValue which annotates errors with location information.
defaultFieldResolver ( $source, $args, $context, ResolveInfo $info ) : mixed | null	If a resolve function is not given, then a default resolve behavior is used which takes the property of the source object of the same name as the field and returns it as the result, or if it's a function, returns the result of calling that function while passing along args and context.
defaultResolveFn ( $source, $args, $context, ResolveInfo $info ) : mixed | null
execute ( Schema $schema, DocumentNode $ast, $rootValue = null, $contextValue = null, array | ArrayAccess $variableValues = null, null $operationName = null ) : ExecutionResult | GraphQL\Executor\Promise\Promise
setDefaultFieldResolver ( callable $fn )	Custom default resolve function
setDefaultResolveFn ( callable $fn )
setPromiseAdapter ( GraphQL\Executor\Promise\PromiseAdapter $promiseAdapter = null )

Private Methods

Method	Description
buildExecutionContext ( Schema $schema, DocumentNode $documentNode, $rootValue, $contextValue, $rawVariableValues, string $operationName = null ) : ExecutionContext	Constructs a ExecutionContext object from the arguments passed to execute, which we will pass throughout the other execution methods.
collectFields ( ExecutionContext $exeContext, ObjectType $runtimeType, SelectionSetNode $selectionSet, $fields, $visitedFragmentNames ) : ArrayObject	Given a selectionSet, adds all of the fields in that selection to the passed in map of fields, and returns it at the end.
completeAbstractValue ( ExecutionContext $exeContext, GraphQL\Type\Definition\AbstractType $returnType, $fieldNodes, ResolveInfo $info, array $path, &$result ) : mixed	Complete a value of an abstract type by determining the runtime object type of that value, then complete the value for that type.
completeLeafValue ( GraphQL\Type\Definition\LeafType $returnType, &$result ) : mixed	Complete a Scalar or Enum by serializing to a valid value, returning null if serialization is not possible.
completeListValue ( ExecutionContext $exeContext, ListOfType $returnType, $fieldNodes, ResolveInfo $info, array $path, &$result ) : array | GraphQL\Executor\Promise\Promise	Complete a list value by completing each item in the list with the inner type
completeObjectValue ( ExecutionContext $exeContext, ObjectType $returnType, $fieldNodes, ResolveInfo $info, array $path, &$result ) : array | GraphQL\Executor\Promise\Promise | stdClass	Complete an Object value by executing all sub-selections.
completeValue ( ExecutionContext $exeContext, Type $returnType, FieldNode[] $fieldNodes, ResolveInfo $info, array $path, &$result ) : array | null | GraphQL\Executor\Promise\Promise	Implements the instructions for completeValue as defined in the "Field entries" section of the spec.
completeValueCatchingError ( ExecutionContext $exeContext, Type $returnType, $fieldNodes, ResolveInfo $info, $path, $result ) : array | null | GraphQL\Executor\Promise\Promise	This is a small wrapper around completeValue which detects and logs errors in the execution context.
doesFragmentConditionMatch ( ExecutionContext $exeContext, $fragment, ObjectType $type ) : boolean	Determines if a fragment is applicable to the given type.
executeFields ( ExecutionContext $exeContext, ObjectType $parentType, $source, $path, $fields ) : GraphQL\Executor\Promise\Promise | stdClass | array	Implements the "Evaluating selection sets" section of the spec for "read" mode.
executeFieldsSerially ( ExecutionContext $exeContext, ObjectType $parentType, $sourceValue, $path, $fields ) : GraphQL\Executor\Promise\Promise | stdClass | array	Implements the "Evaluating selection sets" section of the spec for "write" mode.
executeOperation ( ExecutionContext $exeContext, OperationDefinitionNode $operation, $rootValue ) : GraphQL\Executor\Promise\Promise | stdClass | array	Implements the "Evaluating operations" section of the spec.
fixResultsIfEmptyArray ( $results ) : stdClass | array
getFieldDef ( Schema $schema, ObjectType $parentType, $fieldName ) : FieldDefinition	This method looks up the field on the given type defintion.
getFieldEntryKey ( FieldNode $node ) : string	Implements the logic to compute the key of a given fields entry
getOperationRootType ( Schema $schema, OperationDefinitionNode $operation ) : ObjectType	Extracts the root type of the operation from the schema.
inferTypeOf ( $value, $context, ResolveInfo $info, GraphQL\Type\Definition\AbstractType $abstractType ) : ObjectType | null	Infer type of the value using isTypeOf of corresponding AbstractType
resolveField ( ExecutionContext $exeContext, ObjectType $parentType, $source, $fieldNodes, $path ) : array | Exception | mixed | null	Resolves the field on the given source object. In particular, this figures out the value that the field returns by calling its resolve function, then calls completeValue to complete promises, serialize scalars, or execute the sub-selection-set for objects.
resolveOrError ( ExecutionContext $exeContext, FieldDefinition $fieldDef, FieldNode $fieldNode, callable $resolveFn, mixed $source, mixed $context, ResolveInfo $info ) : Exception | mixed	Isolates the "ReturnOrAbrupt" behavior to not de-opt the resolveField function. Returns the result of resolveFn or the abrupt-return Error object.
shouldIncludeNode ( ExecutionContext $exeContext, $directives ) : boolean	Determines if a field should be included based on the @include and @skip directives, where @skip has higher precedence than @include.
