  Hash::BSON_TYPE

    #to_bson(buffer = BSON::ByteBuffer.new, validating_keys = nil)  ⇒ BSON::ByteBuffer 
  



  

    

Caches the result of to_bson and writes it to the given buffer on subsequent calls to this method. If this method is originally called without validation, and then is subsequently called with validation, we will want to recalculate the to_bson to trigger the validations.


  





  
Parameters:


    
  
  • 
    buffer
    (BSON::ByteBuffer)
    (defaults to: BSON::ByteBuffer.new)
—    
    

    The encoded BSON buffer to append to.
    

    
  
    • 
  
  • 
    validating_keys
    (true, false)
    (defaults to: nil)
—    
    

    Whether keys should be validated when serializing. This option is deprecated and will not be used. It will removed in version 3.0.
    

    
  
    • 



Returns:


    
  
  • 
    (BSON::ByteBuffer)
—    
    

    The buffer with the encoded object.
