Method Details
- sub
  
  SubScope sub()
  
  Open a child scope of this scope, usually for temporary declarations/allocations
  The variables declared in this scope (see decl(BNonVoid, String)) are reserved only with the scope of the try-with-resources block that ought to be used to managed this resource. Local variables meant to be in scope for the method's full scope should just be declared in the root scope.
  
  Returns:
  
  the child scope
- decl
  
  <T extends Types.BNonVoid> Local<T> decl(T type, String name)
  
  Declare a local variable in this scope
  This assigns the local the next available index, being careful to increment the index according to the category of the given type. When this scope is closed, that index is reset to what is was at the start of this scope.
  
  Type Parameters:
  
  T - the type of the variable
  
  Parameters:
  
  type - the type of the variable
  
  name - the name of the variable
  
  Returns:
  
  the handle to the variable
- close
  
  void close()
  
  Close this scope
  This resets the index to what it was at the start of this scope. In general, there is no need for the user to call this on the root scope. This is automatically done by Misc.finish(Emitter).
