jersey - Map JAX-RS @PathParam to POJO Constructor With Annotations -


i want create endpoint has pathparam automatically calls constructor of object injected, has constructor of string argument. spell out in code:

here resource

@get @path("/{apiversion}" + "/item") public response version(@pathparam("apiversion") apiversion apiversion) {     return response.ok().build(); }

i want string automatically used in call apiversion constructor. in apiversion class

public apiversion(string apiversion) {    this.versionstring = apiversion; }

is possible access annotations? not have access resourceconfig.

yes, possible, without annotations other @pathparam, example you've given should work as-is. see https://jersey.github.io/documentation/latest/jaxrs-resources.html#d0e2271 (emphasis mine) :

in general java type of method parameter may:

  1. be primitive type;

  2. have constructor accepts single string argument;

  3. have static method named valueof or fromstring accepts single string argument (see, example, integer.valueof(string) , java.util.uuid.fromstring(string));

  4. have registered implementation of javax.ws.rs.ext.paramconverterprovider jax-rs extension spi returns javax.ws.rs.ext.paramconverter instance capable of "from string" conversion type. or

  5. be list, set or sortedset, t satisfies 2 or 3 above. resulting collection read-only.

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj...

What is happening when Matlab is starting a "parallel pool"? -

running parallel cpu processes in matlab starts command parpool() according documentation , function: [creates] special job on pool of workers, , [connects] matlab client parallel pool. this function takes bit of time execute, on order of 30 seconds. in other multi-cpu paradigms openmp, parallel execution seems totally transparent -- i've never noticed behavior analogous matlab (granted i'm not experienced parallel programming). so, happening between time parpool() called , when finishes executing? takes long? parallel computing toolbox enables run matlab code in parallel using several different paradigms (e.g. jobs , tasks, parfor , spmd , parfeval , batch processing), , run either locally (parallelised across cores in local machine) or remotely (parallelised across machines in cluster - either 1 own, or 1 in cloud). in of these cases, code run on matlab workers , copies of matlab without interactive desktop. if you're intending run on remo...
