/**
 * GraphQL Authentication Decorators
 *
 * These decorators provide GraphQL-specific authentication and authorization
 * functionality by extending the base decorators with GraphQL context options.
 * They maintain the same API as the base decorators but automatically configure
 * for GraphQL execution context.
 *
 * @packageDocumentation
 */
/**
 * GraphQL-specific CurrentUser decorator
 *
 * Injects the currently authenticated user into GraphQL resolver parameters.
 * Uses GraphQL context to extract the user object populated by authentication guards.
 *
 * @param property - Optional property path to extract from the user object (e.g., 'id', 'profile.name')
 * @returns Parameter decorator that injects the current user from GraphQL context
 *
 * @example
 * ```ts
 * @Query(() => IUser, { name: 'GetCurrentUser' })
 * async getCurrentUser(@GraphQLCurrentUser() user: IUser): Promise<IUser> {
 *   return user;
 * }
 * ```
 *
 * @example With property access
 * ```ts
 * @Query(() => String, { name: 'GetUserId' })
 * async getUserId(@GraphQLCurrentUser('id') userId: string): Promise<string> {
 *   return userId;
 * }
 * ```
 */

/**
 * GraphQL-specific AuthToken decorator.
 *
 * Injects the authorization token from GraphQL request context headers.
 * Useful for custom token validation in GraphQL resolvers.
 *
 * @returns ParameterDecorator that injects the raw authorization token string
 *
 * @example
 * ```ts
 * @Query(() => Boolean, { name: 'ValidateToken' })
 * async validateToken(@GraphQLAuthToken() token: string): Promise<boolean> {
 *   return this.authService.validateToken(token);
 * }
 * ```
 */

/**
 * GraphQL Context Parameter decorator
 *
 * Injects the entire GraphQL context object into resolver parameters.
 * Provides access to request, response, and other context data in GraphQL resolvers.
 *
 * @returns Parameter decorator that injects the GraphQL context
 *
 * @example
 * ```ts
 * @Query(() => String, { name: 'GetRequestId' })
 * async getRequestId(@GraphQLContextParam() context: Record<string, unknown>): Promise<string> {
 *   const req = context.req as Record<string, unknown>;
 *   return String(req.headers?.['x-request-id'] ?? '');
 * }
 * ```

/**
 * GraphQL IUser alias for GraphQLCurrentUser
 *
 * Alternative name for GraphQLCurrentUser decorator specifically for GraphQL contexts.
 * Provides the same functionality with a more explicit name.
 *
 * @param property - Optional property path to extract from the user object
 * @returns Parameter decorator that injects the current user
 *
 * @example
 * ```ts
 * @Query(() => IUser, { name: 'GetCurrentUser' })
 * async getCurrentUser(@GraphQLUser() user: IUser): Promise<IUser> {
 *   return user;
 * }
 * ```
 */

/**
 * GraphQL-specific KeycloakClaims decorator
 *
 * Injects the raw Keycloak token claims into GraphQL resolver parameters.
 * Uses GraphQL context to extract the claims object populated by authentication guards.
 * Useful for accessing fine-grained claim information in GraphQL resolvers.
 *
 * @returns Parameter decorator that injects the Keycloak token claims from GraphQL context
 *
 * @example
 * ```ts
 * @Query(() => Object, { name: 'GetTokenInfo' })
 * async getTokenInfo(@GraphQLKeycloakClaims() claims: IKeycloakTokenClaims): Promise<Record<string, unknown>> {
 *   return { issuer: claims.iss, audience: claims.aud };
 * }
 * ```
