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>>

As a complement to the spring-graphql documentation, you may also return:

• 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 interface DataFetchersDelegateTypeWithJson

Parameters:

dataFetchingEnvironment - The GraphQL DataFetchingEnvironment. It gives you access to the full GraphQL context for this DataFetcher

origin - 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 interface DataFetchersDelegateTypeWithJson

Parameters:

dataFetchingEnvironment - The GraphQL DataFetchingEnvironment. It gives you access to the full GraphQL context for this DataFetcher

origin - 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 - The input parameter sent in the query by the GraphQL consumer, as defined in the GraphQL schema.

date - The input parameter sent in the query by the GraphQL consumer, as defined in the GraphQL schema.

json - The input parameter sent in the query by the GraphQL consumer, as defined in the GraphQL schema.

jsons - The input parameter sent in the query by the GraphQL consumer, as defined in the GraphQL schema.
