Scala Macros: Checking for a certain annotation -

Thanks for the reply, I was able to create a function macro as it maps Each field name can be used for the map of a square, such as

  ... attribute model case class user (name: string, age: IT, post: list [string]) extension of the model {Val num.posts: int = posts.length ... def foo = "bar" ...}   
 then this command  
  Val myUser = User ("Foo", 25, list ("Laramum", "Epsom") myUser.asMap   
 Ritter Map   - " , "Number Post" -> 2)   
 This is where  Tupal  s is prepared for the  map  (Travis See brown):  
  ... val pairs = weakTypeOf [T] Declarations.collect {case m: MethodSymbol if m.isAccessor = & gt; Val name = c.literal (m.name.decoded) val value = c.Expr (select (model, m.name)) (name.splice -> value.splice) .tree} ...   
 Now I want to ignore areas that have  @transient  annotations. How do I check that there is a method  @transient  annotation?  
 I am thinking of modifying the snippet above  
  val pairs = weak typing [t] .declarations.collect {Case I: Method Symbol, M. Assessor & amp; ! M.annotations.exists (???) = & gt; Val name = c.literal (m.name.decoded) val value = c.Expr (select (model, m.name)) (name.splice -> value.splice) .tree}   
 But I can not find that I need to write in the  existing  section  @transient  in a  annotation  How will I get it, so can I pass it there?  
 Thanks in advance!   
 
 
 On annotation  val , not on the accelerator. The easiest way to access  val  is to  accessed  method  on MethodSymbol   
  def isTransient ( M: MethodSymbol) = m.accessed.annotations.exists (_.tpe =: = typeOf [scala.transient])   
 Now you can write the following in your  archive < / Code>:  
  Case I: Method Symbol, if M. Associate & amp; amp; ! Haitian (M) = & gt;   
 Note that the version of the  isTransient  that you provided must be defined in your macro, as it needs to be imported from  c.universe < / Code>, but if you are talking about this type in several macros, you can factor it by adding  universe  logic
