@Retention(CLASS) @Target({METHOD})

public @interface Mutation

Declares a GraphQLClient method as a GraphQL mutation. Identical in shape to Query – the value() is the operation document and Var-annotated parameters supply its $variables – but sent as a mutation. The method ends with an OnComplete<GraphQLResponse<T>> callback.

Methods

`public abstract` `String value()`	The GraphQL operation document, e.g. `mutation AddReview($ep: Episode!, $review: ReviewInput!) { createReview(episode: $ep, review: $review) { stars } }`.
`public abstract` `String operationName() default ""`	The operation name to send in the request’s `operationName` field.
