jsons
public List<com.fasterxml.jackson.databind.node.ObjectNode> jsons(graphql.schema.DataFetchingEnvironment dataFetchingEnvironment, STP_TypeWithJson_STS origin) Description copied from interface:DataFetchersDelegateTypeWithJson
This method loads the data for TypeWithJson.jsons. It may return whatever is accepted by the Spring Controller, that is:- A resolved value of any type (typically, a List<com.fasterxml.jackson.databind.node.ObjectNode>)
- Mono and Flux for asynchronous value(s). Supported for controller methods and for any DataFetcher as described in Reactive DataFetcher. This would typically be a Mono<List<com.fasterxml.jackson.databind.node.ObjectNode>> or a Flux<List<com.fasterxml.jackson.databind.node.ObjectNode>>
- Kotlin coroutine and Flow are adapted to Mono and Flux
- java.util.concurrent.Callable to have the value(s) produced asynchronously. For this to work, AnnotatedControllerConfigurer must be configured with an Executor. This would typically by a Callable<List<com.fasterxml.jackson.databind.node.ObjectNode>>
- A CompletableFuture<?>, for instance CompletableFuture<List<com.fasterxml.jackson.databind.node.ObjectNode>>. This allows to use graphql-java java-dataloader to highly optimize the number of requests to the server. The principle is this one: The data loader collects all the data to load, avoid to load several times the same data, and allows parallel execution of the queries, if multiple queries are to be run.
- A Publisher (instead of a Flux), for Subscription for instance
- Specified by:
jsons
in interfaceDataFetchersDelegateTypeWithJson
- Parameters:
dataFetchingEnvironment
- The GraphQLDataFetchingEnvironment
. It gives you access to the full GraphQL context for this DataFetcherorigin
- The object from which the field is fetch. In other word: the aim of this data fetcher is to fetch the jsons attribute of the origin, which is an instance of {ObjectType {name:TypeWithJson, fields:{Field{name:test, type:String, params:[]},Field{name:withArguments, type:String, params:[test:String,date:MyCustomScalarForADate!,long:Long!,boolean:Boolean!,enum:Episode!,json:JSON!,jsons:[JSON!]!]},Field{name:date, type:MyCustomScalarForADate!, params:[]},Field{name:long, type:Long!, params:[]},Field{name:boolean, type:Boolean!, params:[]},Field{name:enum, type:Episode!, params:[]},Field{name:json, type:JSON!, params:[]},Field{name:jsons, type:[JSON!]!, params:[]}}, comments ""}. It depends on your data modle, but it typically contains the id to use in the query.

withArguments
public String withArguments(graphql.schema.DataFetchingEnvironment dataFetchingEnvironment, STP_TypeWithJson_STS origin, String test, Date date, Long _long, Boolean _boolean, SEP_Episode_SES _enum, com.fasterxml.jackson.databind.node.ObjectNode json, List<com.fasterxml.jackson.databind.node.ObjectNode> jsons) Custom field data fetchers are available since release 2.5- Specified by:
withArguments
in interfaceDataFetchersDelegateTypeWithJson
- Parameters:
dataFetchingEnvironment
- The GraphQLDataFetchingEnvironment
. It gives you access to the full GraphQL context for this DataFetcherorigin
- The object from which the field is fetch. In other word: the aim of this data fetcher is to fetch the withArguments attribute of the origin, which is an instance of {ObjectType {name:TypeWithJson, fields:{Field{name:test, type:String, params:[]},Field{name:withArguments, type:String, params:[test:String,date:MyCustomScalarForADate!,long:Long!,boolean:Boolean!,enum:Episode!,json:JSON!,jsons:[JSON!]!]},Field{name:date, type:MyCustomScalarForADate!, params:[]},Field{name:long, type:Long!, params:[]},Field{name:boolean, type:Boolean!, params:[]},Field{name:enum, type:Episode!, params:[]},Field{name:json, type:JSON!, params:[]},Field{name:jsons, type:[JSON!]!, params:[]}}, comments ""}. It depends on your data modle, but it typically contains the id to use in the query.test
