Methods

    

  
      

        
 Determines whether a converion from one flavor to another is supported

 @param  aFromFormatConverter flavor to convert from
 @param  aFromFormatConverter flavor to convert to


        


  
  boolean
  canConvert(in string aFromDataFlavor, in string aToDataFlavor)


      

  

  
      

        
 Converts from one flavor to another.

 @param  aFromFormatConverter flavor to convert from
 @param  aFromFormatConverter flavor to convert to (destination own the memory)
 @returns returns NS_OK if it was converted


        


  
  void
  convert(in string aFromDataFlavor, in nsISupports aFromData, in unsigned long aDataLen, in string aToDataFlavor, out nsISupports aToData, out unsigned long aDataToLen)


      

  

  
      

        
 Get the list of the "input" data flavors (mime types as nsISupportsCString),
 in otherwords, the flavors that this converter can convert "from" (the 
 incoming data to the converter).


        


  
  nsISupportsArray
  getInputDataFlavors()


      

  

  
      

        
 Get the list of the "output" data flavors (mime types as nsISupportsCString),
 in otherwords, the flavors that this converter can convert "to" (the 
 outgoing data to the converter).

 @param  aDataFlavorList fills list with supported flavors
