public class CommonExtension
extends java.lang.Object
implements com.graphql_java_generator.plugin.conf.CommonConfiguration

This class contain the parameters that are common to all Gradle Extensions for this plugin, that is the parameters that are common to all the tasks of this plugin.

This avoids to redeclare each common parameter in each Extension, including its comment. When a comment is updated, only one update is necessary, instead of updating it in each Extension.

    • addRelayConnections

      public boolean addRelayConnections

      True if the plugin is configured to add the relay connection capabilities, as described here and specified in the relay connection specification.

      The plugin reads the GraphQL schema file(s), and enrich them with the interface and types needed to respect the Relay Connection specification. The entry point for that is the @RelayConnection directive. It is specific to this plugin. It can be added to any field, that is, typically: queries, mutations, interface's fields, type's field. It must be declared in the given GraphQL schema file(s) like this: 

       directive @RelayConnection on FIELD_DEFINITION

      When addRelayConnections is set to true, here is what's done for each field that is marked with the @RelayConnection directive:

      • The field type, whether it's a list or not, is replaced by the relevant XxxConnection type. For instance the query allHumans(criteria: String): [Human] @RelayConnection is replaced by allHumans(criteria: String): HumanConnection, and the human's field friends: Character @RelayConnection is replaced by friends: CharacterConnection. Please note that :
        • The @RelayConnection directive is removed in the target schema
        • If the @RelayConnection is set on a field of an interface, it should be set also in the same field, for each type that implements this interface. If not, a warning is generated. The directive is applied on the interface and its implementations's field, whether or not the directive is actually set in the implementing classes.
        • If the @RelayConnection is not set on a field of an interface, but is set in the same field, for one type that implements this interface, then an error is generated. The directive is applied on the interface and its implementations's field, whether or not the directive is actually set in the implementing classes.
        • Input type's fields may not have the @RelayConnection directive
      • For each type marked at least once, with the @RelayConnection directive (the Human type, and the Character interface, here above), the relevant XxxConnection and XxxEdge type are added to the in-memory schema.
      • The Node interface is added to each type marked at least once, with the @RelayConnection directive (the Human type, and the Character interface, here above). Of course, these types must have a mandatory field id of type ID that is not a list. If not, then an error is thrown.

      As a sum-up, if addRelayConnections is set to true, the plugin will add into the in-memory GraphQL schema:

      • Check that the @@RelayConnexion directive definition exist in the GraphQL schema, and is compliant with the above definition.
      • Add the Node interface in the GraphQL schema (if not already defined). If this interface is already defined in the given schema, but is not compliant with the relay specification, then an error is thrown.
      • Add the PageInfo type in the GraphQL schema (if not already defined). If this type is already defined in the given schema, but is not compliant with the relay specification, then an error is thrown.
      • All the Edge and Connection type in the GraphQL schema, for each type that is marked by the @@RelayConnexion directive.
