Class: Psych::Coder

Relationships & Source Files
Inherits: Object
Defined in: ext/psych/lib/psych/coder.rb

Overview

If an object defines encode_with, then an instance of Coder will be passed to the method when the object is being serialized. The Coder automatically assumes a Nodes::Mapping is being emitted. Other objects like Sequence and Scalar may be emitted if #seq= or #scalar= are called, respectively.

    #map(tag = @tag, style = @style) {|_self| ... } 
  



  

    

Emit a map.  The coder will be yielded to the block.


  





  
Yields:


    
  
  • 
    (_self)
  
    •
