Class GraphQLObjectMapper

  • public class GraphQLObjectMapper
extends java.lang.Object
    This class is a wrapper around an ObjectMapper. It allows the GraphQL plugin generated code to use its own ObjectMapper, without interfering with the containing app. This insures that the containing app can configure and use "its" ObjectMapper as it wants, and that the GraphQL plugin can use its own ObjectMapper with its own configuration.
    This class is not Spring bean, as it is configured for each request, with the list of alias for this GraphQL request.

        It may be null, in which case enumeration values won't be properly deserialized.
        value - The value to parse
        Returns:
        The parsed value. That is, according to the above sample: a String, a List or a List>
