Greetapp – Specification Pattern Example

https://github.com/JonnyD/greetapp-api-java

Small example of the Specification pattern:

/**
     * GET  /greets-by-user/:groupId : get all the greets by group.
     *
     * @return the ResponseEntity with status 200 (OK) and the list of greets in body
     */
    @GetMapping("/greets-by-group/{groupId}")
    @Timed
    public Object getAllGreetsByGroup(@PathVariable Long groupId) {
        log.debug("REST request to get all Greets by user");
        List<Greet> greets = greetService.getByGang(groupId);

        Optional<Gang> optionalGang = this.gangService.getById(groupId);
        Gang gang = optionalGang.get();

        CanViewGang canViewGang = new CanViewGang(this.userService);
        if (!canViewGang.isSatisfiedBy(gang)) {
            return new ResponseEntity<>(HttpStatus.FORBIDDEN);
        }

            }
        }

Results

// get result
$result = $peggy->result()->get($crawlName);
$urls = $result->getUrls(); // Returns the results of the crawl specified by CRAWL_NAME. This will return a 404 if no results have been posted. Example Url: "http://s3.amazonaws.com/results1"

Apps

// upload app
$request = $peggy->app()->createAppRequest($name, $filePath);
$peggy->app()->upload($request);
