Class mxCodecRegistry

1. Define a default codec with a new instance of the object to be handled.

   var codec = new mxObjectCodec(new mxGraphModel());
   

2. Define the functions required for encoding and decoding objects.

   codec.encode = function(enc, obj) { ... }
   codec.decode = function(dec, node, into) { ... }
   

3. Register the codec in the .

   mxCodecRegistry.register(codec);
   

mxObjectCodec.decode may be used to either create a new instance of an object or to configure an existing instance, in which case the into argument points to the existing object. In this case, we say the codec "configures" the object.
