#deserialize(buffer, options = {}) ⇒ Array<Symbol>

Deserializes vector by decoding the symbol according to its mask

Parameters:

  • buffer (String) —

    Buffer containing the vector to be deserialized.

  • options (Hash) (defaults to: {}) —

    This method does not currently accept any options.

Returns:

  • (Array<Symbol>) —

    Flags contained in the vector

def deserialize(buffer, options = {})
  vector = buffer.get_int32
  flags = []
  @masks.each do |flag, mask|
    flags << flag if mask & vector != 0
  end
  flags
end


  








  

    #serialize(buffer, value, validating_keys = nil)  ⇒ String 
  



  

    

Serializes vector by encoding each symbol according to its mask


  





  
Parameters:


    
  
  • 
    buffer
    (String)
—    
    

    Buffer to receive the serialized vector
    

    
  
    • 
  
  • 
    value
    (Array<Symbol>)
—    
    

    Array of flags to encode
    

    
  
    • 
  
  • 
    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.
